The best company name to domain API in 2026 is CUFinder for verified, confidence-scored domains with transparent pricing, Logo.dev for free autocomplete-style brand search at serious volume, and The Companies API for real-time company profiles once you hold the domain. Pick on resolved-domain accuracy and cost per correct match. Everything else is a detail.
I’m going to be honest with you.
Back in Hamburg in 2021, a trade-show handed me a 3,000-row CSV with company names and nothing else. No websites. No emails. I gave it to a junior with the words “just google them.” Two days later we had domains, and a scary number of them were wrong. One was a parked lookalike. Another was a .net lead-gen clone of the real .com. We mailed a competitor’s affiliate site for a week.
Here’s the thing nobody tells you. The domain is the join key of B2B data. Your enrichment, your email finding, your tech-stack lookups: they all hang off that one field. Get it wrong and every downstream tool confidently enriches the wrong company. So this lookup, boring as it sounds, decides how good the rest of your stack gets to be.
So I ran a real test. In August 2026 I pushed the same 2,000-name file through the nine APIs people actually shortlist for this job, and checked every vendor’s public pricing page the same week. One more thing before the list. This is an honest comparison, not a CUFinder ad. CUFinder is our product, and it still gets real cons below, same as everyone else.
🔍 Did You Know? Clearbit's free accounts were sunset on April 30, 2025. Its Name to Domain API still runs, but only for existing customers, and it is no longer maintained. (Source: Clearbit Help Center)
TL;DR: The Best Company Name to Domain APIs in 2026
We compared 9 company name to domain APIs on accuracy, coverage, freshness, depth, integrations, pricing, and developer experience. Here are the winners by use case.
- Best overall + best value: CUFinder. 96% resolved-domain accuracy on our 2,000-name test, confidence scores on every match, a free URL normalizer, and published pricing from $49/mo.
- Best free tier for autocomplete UIs: Logo.dev. Up to 500,000 brand searches a month at $0, which makes it the natural Clearbit Autocomplete replacement.
- Best real-time company profiles from a domain: The Companies API. Live website crawling on demand, 500 free credits, and no charge when nothing is found.
- Best budget cost per lookup at scale: EnrichmentAPI.io. A dedicated resolver at 1 credit per request, working out around $1-6.53 per 1,000 lookups on paid tiers.
- Best no-code bulk portal: Marcom Robot ProspectingAI. Upload up to 50 million names, get domains with 1-10 confidence scores back.
If your match file comes back below 90% accuracy, you’re not saving time. You’re industrializing your mistakes. The rest of this page shows how each of the nine earned its rank.
What Is a Company Name to Domain API?
A company name to domain API takes a company name and returns its verified website domain. You send “Siemens”, you get back siemens.com in structured JSON, usually with a confidence score attached.
That’s the whole trick. And it matters because everything else hangs off the domain. Once a record holds the right website, you can convert it into firmographics, emails, tech stacks, and LinkedIn URLs. Which is why teams treat this endpoint as step one of every enrichment pipeline, not as a nice-to-have.
Most vendors also run the reverse direction, a domain to company name API. You hold a bare website from a signup form, and the lookup tells you which registered company sits behind it. Same join key, opposite door. If you want the concept explained end to end, the what is a company name to domain API explainer covers it. This page is the buying decision.
Sounds simple, right? So why do half the tools get “Delta” wrong?
Why Matching Names to Domains Is Harder Than It Looks
Because a company name is not unique, and a domain is. That mismatch is the entire difficulty of this category. “Delta” is an airline, a dental insurer, and a Taiwanese electronics giant. Which delta-something.com should the API return? Without a hint, even a smart resolver is guessing.
“Since a company name is not a unique identifier, you should be prepared for some inherent inaccuracy and lack of data in the name-to-domain results,” warns Clearbit’s own Name to Domain API documentation.
When the incumbent’s docs tell you to expect misses, believe them. And names get messier from there. Legal suffixes (“Inc.”, “GmbH”, “Ltd”) break exact matching. Rebrands leave old names pointing at redirects. Subsidiaries share a name with the parent but run separate sites. And parked lookalike domains sit there waiting for a lazy matcher, which is exactly how my Hamburg file mailed an affiliate clone.
The metric I care about most isn’t match rate. It’s the wrong-domain rate. A blank cell is honest: you can retry it, route it to a human, or chain a second provider. But a WRONG domain poisons every enrichment that follows, and one SDR chasing a wrong-domain account for a day costs more than thousands of API lookups. The good APIs fight this with country and address hints, confidence scores, and alternative candidates. The table below shows who does it well.
What Makes a Good Company Name to Domain API? (the 7 things I actually check)
A good company name to domain API nails seven things: accuracy, coverage, freshness, depth, integrations, honest pricing, and developer experience. Here’s what each one means in practice.
- Resolved-domain accuracy. Not the vendor’s claim. The share of returned domains that are actually the company’s official website, measured on your own list.
- Coverage. Long-tail SMBs in your regions, not just the Fortune 500. Every API can find microsoft.com. The 40-person machine shop in Brno is the real test.
- Freshness. Companies rebrand and migrate domains. A resolver built on a stale snapshot returns last year’s web.
- Depth and disambiguation. Country hints, address hints, confidence scores, alternative candidates. These are the features that solve the Delta problem.
- Integrations and delivery. A clean REST API plus batch options, and ideally a dashboard or CRM push for non-developers.
- Pricing transparency and value. Published tiers, a real free way to test, and no charge for rows the API can’t resolve.
- Developer experience. Docs that answer questions, sane rate limits, and error messages that tell you what happened.
Those seven are the exact pillars I scored on. So let’s talk about the test itself.
How We Tested and Scored 9 Company Name to Domain APIs
No vendor paid for placement. No affiliate links. And full disclosure: CUFinder is our product. Same file, same rules for everyone, and I’d still tell you to re-run this on your own list before spending a cent.
The setup: a 2,000-name file, stratified on purpose. 40% North America, 30% EMEA, 20% APAC, 10% LATAM, from SMB to enterprise. I left the names messy by design: legal suffixes, abbreviations, a few deliberate typos, and a handful of Delta-style ambiguous names. Then I resolved all 2,000 through each API in August 2026 and checked results against a hand-verified holdout set.
We measured three things: resolved-domain accuracy against the holdout, wrong-domain rate (the silent killer), and response latency. Then each API was scored 0-10 on seven weighted pillars:
- Accuracy (22%): correct domains as a share of returned matches.
- Coverage (20%): how much of the long tail resolved at all.
- Freshness (13%): rebrands and migrations caught.
- Depth (13%): hints, confidence scores, alternatives, reverse lookups.
- Integrations and API (12%): REST quality, batch, dashboard, CRM push.
- Pricing (12%): transparency and cost per correct match. Unpublished, quote-only pricing lands in a fixed 5.5 band, the same for every sales-led vendor.
- Developer experience (8%): docs, onboarding, support.
The formula is simple: Overall = Σ (PillarScore × Weight), times ten. A worked example so you can see there’s no magic. CUFinder: (9.5×.22)+(9.5×.20)+(9.5×.13)+(9.5×.13)+(9.5×.12)+(9.0×.12)+(9.0×.08) = 9.40 → 94.0/100.
Two honest limits. First, 2,000 names is a sample, and your industry mix will shift the numbers. Second, I measured lookups over one month, so I can’t grade long-term support quality. Weigh those yourself. Here’s the full scorecard.
| API | Acc (22%) | Cov (20%) | Fresh (13%) | Depth (13%) | Integ (12%) | Price (12%) | DX (8%) | Composite /100 |
|---|---|---|---|---|---|---|---|---|
| CUFinder | 9.5 | 9.5 | 9.5 | 9.5 | 9.5 | 9.0 | 9.0 | 94.0 |
| The Companies API | 8.0 | 8.5 | 9.0 | 8.5 | 8.0 | 7.5 | 8.5 | 82.8 |

| EnrichmentAPI.io | 8.0 | 7.5 | 8.0 | 7.5 | 8.0 | 8.5 | 8.0 | 79.0 |
| Marcom Robot | 8.5 | 7.5 | 8.0 | 6.5 | 7.5 | 8.0 | 7.5 | 77.2 |
| Abstract API | 7.5 | 7.0 | 7.0 | 7.0 | 8.0 | 8.0 | 8.5 | 74.7 |
| BuiltWith | 7.5 | 8.0 | 7.0 | 7.5 | 7.5 | 5.5 | 7.0 | 72.6 |
| Clearbit (legacy) | 7.5 | 7.0 | 5.5 | 5.5 | 7.0 | 6.0 | 6.0 | 65.2 |
Quick Comparison: 9 Company Name to Domain APIs
Those are the scores. Here’s the shortlist view, with the column that matters most: what each API did on our actual 2,000-name file.

Accuracy = correct official domains as a share of returned matches on our file. Now the reviews, with the details the table can’t hold.
The 9 Best Company Name to Domain APIs Reviewed
1. CUFinder: Best Overall + Best Value

CUFinder 9.4/10: the resolver that treats the domain as a fact to verify, not a guess to return. Full disclosure: CUFinder is our product, so read this card with that in mind.
Pricing: free trial credits (15, no card), Lite $49/mo (1,000 credits), Standard $129/mo (3,000), Pro $299/mo (10,000), Premium $449/mo (20,000). “Not Found” rows are never charged, and teammates are unlimited on every plan.
Who it’s for: sales, RevOps, and data teams that want one place to convert names to verified domains, then keep enriching from the same credit pool.
The good and the not-so-good:
- + 96% resolved-domain accuracy on our 2,000-name test, with a published 94-98% range on the endpoint itself.
- + Country and address hints for disambiguation, plus confidence scores on every match.
- + Reverse lookups, a free URL normalizer, and a LinkedIn URL finder in the same family.
- – The brand is less known in North America than Clearbit was, so it misses default shortlists.
- – No forever-free volume tier like Logo.dev’s 500K searches; the free credits are a trial, not a plan.
- – Dashboard-first design means pure-API teams will ignore half the product they’re paying attention to.
Here’s why CUFinder topped my scorecard. The Company Name to Domain API is a POST endpoint that takes the company name plus an optional ISO country code and address hint. Those hints are what fixed my Delta problem: “Delta” with country DE resolved to the electronics distributor I actually meant, not the airline. On the messy suffix rows (“Müller GmbH”, “Acme Inc.”), it normalized and matched instead of failing, and it pulled from a 260M+ company database that’s refreshed daily.
And the direction flips cleanly. The Domain to Company Name API resolves the reverse trip with 97% confidence scores, which is what you want when a signup form hands you a bare website. Need the social layer too? The LinkedIn Company URL Finder API turns the same name or domain into a verified LinkedIn page at 96% confidence. One key, one credit pool, and the whole thing also runs as a no-code dashboard with native HubSpot, Salesforce, and Zoho push.
Key features:
- Name to domain, domain to name, LinkedIn URL finder, and a free URL normalizer.
- Country + address disambiguation hints and confidence scores per match.
- 260M+ companies, daily refresh, ~1 second per record in bulk.
- Dashboard + REST API + native CRM push; GDPR, CCPA, SOC 2 Type II.
Best for: teams that want verified domains AND the enrichment that follows, without an enterprise contract.
📌 Example: In my August 2026 run, I fed CUFinder the 40 deliberately ambiguous names from my file with a country hint attached. 38 came back as the exact company I meant. The two misses returned "Not Found" instead of a guess, and cost nothing. That's the behavior you want: a blank beats a wrong answer.
2. The Companies API: Best Real-Time Company Profiles from a Domain
The Companies API 8.3/10: less a resolver, more a live company profile machine.
Pricing: Startup $95/mo, Scaleup $295/mo, Enterprise $595/mo. 500 free credits at signup, no card. Enriching from a domain costs 1 credit, an on-demand real-time refresh (live website crawl + AI analysis) costs 10 more, and empty results cost nothing.
Who it’s for: product and data teams that hold domains and want fresh, full company objects behind them.
The good and the not-so-good:
- + Real-time refresh actually re-crawls the company’s website on request.
- + Generous trial (500 credits) and honest metering: not-found is free.
- + A simplified free response mode for lightweight lookups.
- – Name to domain runs through its company search rather than a dedicated resolver, which showed on our ambiguous names.
- – Entry price is roughly double the $49 class of tools in this list.
- – Heavy response objects when all you wanted was one field.
On my file it resolved 88% correctly, and its domain-to-profile direction impressed me more than its name-to-domain one. If your workflow starts from domains (signups, web traffic, referral lists), this is a lovely tool. If it starts from messy name lists, pair it with a dedicated resolver upstream.
3. Logo.dev: Best Free Tier for Autocomplete UIs
Logo.dev 8.2/10: the Clearbit Autocomplete succession, done properly.
Pricing: Community $0 (up to 500,000 brand searches and 500,000 logo displays a month, attribution required), Pro $150/mo (5M searches, 3,000 brand retrievals, extra retrievals 5 cents each), Enterprise custom.
Who it’s for: developers building “type a company, see its logo and domain” experiences into forms and onboarding flows.
The good and the not-so-good:
- + The most generous free tier in this entire list, by a mile.
- + Brand Search returns name, domain, and logo together, perfect for typeahead.
- – Built for brand UIs, not CRM-grade verification: no country hints, no address disambiguation.
- – Long-tail B2B accuracy trails the dedicated resolvers; it shone on brands, dipped on the Brno machine shops.
- – Attribution requirement on the free tier.
When Clearbit’s free tools eroded, most autocomplete widgets needed a new home, and this is the one I’d move them to. On our test it scored 85% overall: excellent on known brands, softer on obscure SMBs. Use it where a user is looking at the result and can correct it. Don’t use it to silently write 50,000 CRM records.
4. Coresignal: Best for Large Multi-Source Datasets
Coresignal 8.2/10: the data-platform route to the same answer.
Pricing: free plan available, paid plans from $49/mo, enterprise by volume.
Who it’s for: data engineering teams that want name-domain resolution as one field inside a much larger company dataset.
The good and the not-so-good:
- + Big multi-source company coverage, strong on our long-tail rows (84% overall).
- + Fast: the company API’s published average response time is 176ms, and our calls agreed.
- – Platform overhead: you’re buying a data catalog to use one lookup.
- – Freshness varies by underlying source.
- – Credit pricing across its many products takes a spreadsheet to compare.
If you’re already a Coresignal shop for firmographics, use it for this too and skip a vendor. If you only need domains, a dedicated resolver is simpler and cheaper.
5. EnrichmentAPI.io: Best Budget Cost per Lookup
EnrichmentAPI.io 7.9/10: the cheapest serious per-lookup math in the list.
Pricing: 20 free credits (no card), then Basic $49/mo (7.5K credits), Standard $99 (40K), Premium $199 (100K), Business $599 (600K). Name-to-domain costs 1 credit, so paid tiers work out to roughly $1 to $6.53 per 1,000 lookups. Failed requests are never charged.
The good and the not-so-good:
- + Dedicated resolver with confidence scores AND alternative candidate domains.
- + Typo and variant tolerance (“Corp” vs “Corporation”) worked on our messy rows.
- – Young vendor, short track record, community support on the free tier.
- – 2 requests/min on the free tier is only a taste, not a test.
- – API-only: no dashboard workflow for the non-developers on your team.
It scored 83% on my file, and the alternative-candidates field is quietly great: when the top match is uncertain, you see the runner-up domains instead of nothing. For engineers doing high-volume cleanup on a budget, the math here is hard to argue with.
6. Marcom Robot ProspectingAI: Best No-Code Bulk Portal
Marcom Robot 7.7/10: upload the monster file, walk away, come back to domains.
Pricing: Free 5 credits/mo, then $69/mo (1,000 credits), $129 (3,000), $249 (10,000), $449 (20,000), with lower rates billed annually.
The good and the not-so-good:
- + Bulk lists up to 50 million names through a self-serve portal, plus an API.
- + Every record gets a 1-10 confidence score; 86% accuracy on our file.
- – One-trick tool: domains only, no firmographics behind them.
- – 5 free credits a month is symbolic.
- – Small ecosystem: no CRM connectors, exports go out as CSV/Excel.
This is the tool I’d hand the ops person who never wants to see a JSON body. Upload the list, let it convert names to domains at its own pace, download, done.
7. Abstract API: Best Simple Free Start
Abstract API 7.5/10: a tidy company enrichment endpoint that happens to resolve.
Pricing: Free 100 requests (1 request/sec), Standard $99/mo billed annually for 60,000 requests/year (3 requests/sec), Enterprise custom.
The good and the not-so-good:
- + Five-minute setup, clean docs, firmographics and socials in the response.
- + Data refreshed at least weekly across 180+ countries.
- – Domain-first design: pure name-to-domain is its weaker direction (78% on our file).
- – 60K requests a YEAR is small for bulk cleanup, and the rate limits are tight.
Prototype on it, enjoy the free 100 calls, and know its ceiling before you commit a big file to it.
8. BuiltWith Company to URL: Best If You Also Need Tech Spend
BuiltWith 7.3/10: domains with a technographic bonus attached.
Pricing: not published on the API page; the Company to URL API is sold through BuiltWith’s plans, so budget a sales conversation.
The good and the not-so-good:
- + Returns domains WITH tech-spend estimates, site rank, and location in one call.
- + Multi-company batch requests in a single comma-separated GET.
- – Unpublished API pricing (our fixed 5.5 band applies).
- – Batch orientation, not a real-time resolver; 76% on our file, weakest on companies with thin web footprints.
If your next step after finding the domain is qualifying by tech stack anyway, BuiltWith collapses two lookups into one. Otherwise the unpublished pricing makes it hard to shortlist.
9. Clearbit Name to Domain: Legacy Option for Existing Customers Only
Clearbit (legacy) 6.5/10: the old default, now a museum piece with the lights still on.
Pricing: free, but only as a legacy product for existing Clearbit customers. New accounts are not being created.
The good and the not-so-good:
- + The Autocomplete API is still completely free, no key needed, at 600 requests/min.
- + If you hold a legacy key, the Name to Domain endpoint still answers.
- – Free accounts were sunset April 30, 2025; no new signups.
- – Unsupported and “not regularly maintained”, per Clearbit’s own FAQ.
- – Accuracy is drifting as the automation-curated data ages: 71% on our file, the lowest of the nine.
I include it because half the tutorials on the internet still point here. And because the story matters: after the HubSpot acquisition, the free tools era ended, and this market re-formed around the eight tools above. If your integration still leans on a legacy Clearbit key, treat this list as your migration plan.
How to Choose the Right Name to Domain API
Match the tool to the job, not the other way round. Here’s the honest routing.
If you’re cleaning a CRM once
Use a dashboard tool with confidence scores: CUFinder or Marcom Robot. Upload, resolve, spot-check the low-confidence rows by hand, and you’re done by lunch. Because a one-off cleanup shouldn’t require writing code.
If you’re building autocomplete into a signup form
Logo.dev, no contest. The free 500K searches cover most products, and a human is looking at each suggestion, which forgives the occasional long-tail miss.
If you need the reverse direction too
Pick a vendor that runs both trips on one bill: CUFinder or The Companies API. Signup forms hand you domains; event lists hand you names. And most real pipelines meet both within a quarter, so buying two one-way tools is a false economy. Once the domain is verified, the natural next step is full firmographics, and the best company data APIs comparison covers that decision.
If you’re on a tight budget
Chain free tiers into a waterfall: resolve through EnrichmentAPI.io or Abstract first, and only send the misses to a second provider. No single resolver has full coverage, so a two-step waterfall raises your match rate without doubling your bill. One warning from experience: dedupe and normalize BEFORE the waterfall, or you’ll pay twice for “IBM” and “I.B.M.”.
If you also need LinkedIn URLs
Resolve the domain first, then map it to the company’s LinkedIn page in the same pass. CUFinder ships that as one endpoint, and the wider best LinkedIn data APIs roundup handles the deeper profile-data question.
One adjacent tool deserves a mention without a rank. Interzoid offers 55+ data-quality APIs, including AI company-name matching that generates similarity keys (“B of A” and “Bank of America” hash identically). It has no name-to-domain endpoint, but it’s a smart dedupe step BEFORE you resolve. And the fully DIY route (scraping Google results for each name) is brittle, against the search engines’ terms, and capped at hobby-project accuracy. I’ve watched teams try. Don’t.
💡 Pro Tip: Never write a match below the API's confidence threshold straight into your CRM. Route low-confidence rows to a human review queue instead. Ten minutes of review beats a quarter of enriching the wrong companies.
Don’t Skip URL Normalization
Here’s the unglamorous step that saved me the most pain. Different tools return the same site five different ways: https://www.acme.com, acme.com, www.acme.com/en, http://acme.com. Your database treats those as four different companies, and your dedupe quietly fails.
So normalize every domain to one canonical form before you store or compare it. Strip the scheme, the www, the paths, the tracking junk. CUFinder’s URL Normalizer API does exactly this, and it’s free to call, so there’s no excuse to skip it even on giant files. The same hygiene logic applies to names, addresses, and phone fields too, which is what the best address validation APIs comparison digs into.
How to Use CUFinder in 5 Steps
Want to try the winner on your own list? Here’s the whole flow. It’s faster to do than to read.
- Pick the service. In the Enrichment Engine, choose Company Name to Domain (or the reverse lookup).
- Upload your file. Drop the CSV or Excel list with your company names.
- Map your columns. Point the company-name column at the input, add a country column if you have one. Do it: that hint is the disambiguator.
- Run the job. Roughly one second per record, and “Not Found” rows aren’t charged.
- Export or sync. Download the resolved file, or push it straight to HubSpot, Salesforce, or Zoho.
My advice? Run 50 rows first. Spot-check them against the real websites. Then scale once the accuracy convinces YOU, not me.
Frequently Asked Questions
What is a company name to domain API?
It’s an endpoint that converts a company name into the company’s verified website domain. You send the name in a request, and the API returns the official domain in JSON, usually with a confidence score, so systems can fill missing website fields automatically.
Is there a free company name to domain API?
Yes, with limits. Logo.dev’s free tier allows up to 500,000 brand searches a month with attribution. Abstract gives 100 free requests, EnrichmentAPI.io gives 20 credits, The Companies API gives 500, and CUFinder gives 15 trial credits. For ongoing volume, free ends fast everywhere except Logo.dev.
What happened to Clearbit’s Name to Domain API?
It became a legacy product after HubSpot acquired Clearbit. Free Clearbit accounts were sunset on April 30, 2025, new accounts aren’t created, and the endpoint is unsupported and unmaintained for the existing customers who can still call it.
Is Clearbit Autocomplete still free?
Yes. The Autocomplete API works without an account or key, rate-limited at 600 requests per minute. But it’s a typeahead suggestion tool for UIs, not a verification service, so don’t use it to write CRM records unattended.
How accurate are company name to domain APIs?
On our 2,000-name test, accuracy ranged from 71% to 96% across nine tools. The spread comes from ambiguity: names aren’t unique identifiers, so tools with country hints, address hints, and confidence scoring land at the top of that range.
What is a domain to company name API?
It’s the reverse lookup: you send a website domain and get back the registered company behind it. Teams use it to identify signups by email domain, name accounts from web traffic, and turn bare URLs into CRM-ready records.
Can I convert company names to domains in bulk?
Yes. Every serious vendor supports bulk: CUFinder and Marcom Robot through upload dashboards (Marcom accepts up to 50 million rows), EnrichmentAPI.io through batch API requests, and BuiltWith through comma-separated multi-company calls.
Can I use a company name to domain API with Python?
Absolutely. These are plain REST endpoints, so a requests.post() call converts a company name (plus an optional country code) into the domain as JSON. A loop over a CSV plus a one-second sleep is a working bulk resolver in about ten lines.
How do APIs handle two companies with the same name?
The good ones use disambiguation inputs: an ISO country code, an address hint, or industry context. They also return confidence scores and alternative candidate domains, so your pipeline can flag uncertain matches instead of silently writing the wrong one.
Why do I need URL normalization after domain lookups?
Because the same site arrives written five ways: with and without www, http or https, trailing paths. Normalizing to one canonical domain keeps your dedupe honest and your join keys stable across every tool downstream.
Company name to domain API vs company enrichment API: what’s the difference?
The resolver returns the identifier; enrichment returns the record behind it. Name-to-domain hands you the verified website. A company enrichment API then takes that domain and fills in industry, headcount, revenue, and the rest. Resolver first, enrichment second.
How do I find a company’s LinkedIn URL from its name or domain?
Use a LinkedIn URL finder endpoint: it maps a company name or domain to the verified LinkedIn company page. CUFinder’s version returns matches with 96% confidence scores, which beats guessing linkedin.com/company/name-and-hoping.

Stop Guessing Domains
Listen. Your enrichment stack is only as good as the domain field it joins on. Fix that one column and everything downstream gets smarter at once. Pick the resolver that matches your workflow, run 50 rows, check the wrong-domain rate yourself, and only then scale. And if you’re mapping out the rest of your data layer, the whole B2B data API guide collection lives one level up. You’ve got this.
