Company Enrichment by Domain: No API Key

What does Company Profile by Domain do?

Company Profile by Domain turns a list of company domains into firmographic rows. Paste monzo.com, https://www.hubspot.com/pricing or sales@apify.com and get one row per company: company name, legal name, description, industry, founding year, HQ city and country, LinkedIn company page, social accounts, tech stack, mail provider, SPF/DMARC and, for UK companies, the Companies House number, status, SIC codes and registered office.

It works as a company enrichment API for CRMs, lead lists and AI agents: no API key, no login and no monthly plan. It reads the company's own homepage, public DNS, the public UK register and Wikidata over plain HTTP, so a domain takes about a second and a 1,000-domain batch costs $5.

It returns company data only. Founders, employees and contact people are never collected.

Use cases for this company enrichment API

• CRM and lead-list enrichment. Turn the domain column of a CRM export or a CSV into industry, HQ country, LinkedIn page and tech stack.
• Lead scoring and routing. Route accounts by country or industry, or score them by tech stack and mail provider.
• Sales prospecting by technology. Find which prospects run a given CMS, analytics tool or chat widget.
• KYB and supplier checks for UK companies. Confirm the company behind a website is Active in Companies House before onboarding.
• Email deliverability and security audits. See the mail provider, SPF and DMARC policy for every domain in a list.
• AI agents. One call with a domain returns a compact, self-describing company profile.

Result status (tri-state output)

Every domain gives exactly one row. ok rows are billed. A domain that does not exist in DNS is not_found; a domain whose website cannot be read and that no source can name is error, still with its mail provider and DMARC columns filled. Parked and for-sale domains (redirects to HugeDomains, Sedo, Dan, Afternic, GoDaddy and similar, "this domain is for sale" pages, placeholder pages whose only name is the domain itself) are also error rows, so a lead list full of dead domains costs nothing. All of these are free.

How much does it cost to enrich a company domain?

Pay per result: $5 per 1,000 company profiles. Rows with status not_found or error are free. Compute, DNS and register lookups are included; no proxy is needed.

Event	Price	Charged when
apify-actor-start	$0.00005	Once per run, when it starts.
result	$0.005	Each company profile saved with status ok.

Domains	Cost
100	$0.50
1,000	$5.00
10,000	$50.00

The Actor stops gracefully when your run's maximum charge is reached.

Integrations, exports and API access

Run it from the Apify API, the JavaScript or Python client, the Apify CLI or on a Schedule. Send the dataset to Google Sheets, Airtable, HubSpot, Make, n8n, Zapier or a webhook. AI agents can call it through the Apify MCP server.

Limitations

• Big consumer brands sometimes block datacenter visitors (HTTP 403). The Actor then fills name, HQ and industry from Wikidata when the domain has a Wikidata item; otherwise the row is a free error row with the DNS and mail columns.
• HQ city is only as good as what the company publishes: schema.org markup on its site, the UK registered office, or Wikidata. A tld source means the country comes from a country-code domain only.
• Industry is a sector guess (about 20 labels), not a NAICS code. uk-sic is the most reliable source, keywords the least.
• Companies House matching uses the company number printed on the site, or an exact name match in the register search. It never guesses fuzzy matches, so some UK companies stay unmatched.
• No headcount ranges from LinkedIn, no revenue, no funding and no contact people.
• Results reflect the website and registers at the time of the run.

FAQ

Do I need an API key or an account with a data vendor? No. The Actor reads the company's public homepage, public DNS, the public Companies House register and Wikidata.

How fast is it? About one second per domain, ten domains in parallel.

Why did a domain come back as error? The website blocked the request or names no organisation, and no other source knew the company. You are not billed for it. The warnings column says what happened.

Does it return employees or contact e-mails? No, by design. It returns company-level data only; e-mail addresses and phone numbers in descriptions are redacted.

Can I enrich 10,000 domains? Yes. Paste them (or send them through the API) and set Maximum results to at least that number.

Can I use it from an AI agent or MCP client? Yes. It runs with no input, accepts plain domain strings and every row explains itself with status and error.

What if a site changes? Rows degrade to fewer filled columns or a free error row, never to made-up values. Report problems in the Issues tab with the run ID.

Legal and data-protection notice

This Actor extracts company-level information that companies publish about themselves on their own websites and in public DNS, plus public records from the UK Companies House register (Open Government Licence v3.0) and Wikidata (CC0). It does not collect founders, employees, officers, persons with significant control or contact people, it redacts e-mail addresses and phone numbers found in descriptions, and it does not log in or work around access controls. A small business's address can still be a home address, so your results could contain personal data. Personal data is protected by the UK GDPR, the EU GDPR and other regulations around the world. You should not process personal data unless you have a legitimate reason to do so. If you are unsure whether your reason is legitimate, consult your lawyers. You are responsible for complying with the terms of the websites you look up and with applicable law when using the extracted data.
