Company Intelligence API API
The Company Enrichment API resolves a domain to a company as clean JSON.
🤖 Using an AI assistant? Copy this link into ChatGPT / Claude / Cursor — it reads every endpoint and parameter instantly and tells you if this API fits your use case.
The primary company_domain endpoint returns the final domain, match type, confidence and canonical company name, with a rich variant and batch. It is built for sales intelligence and CRM enrichment that need to turn a domain into a clean company record. One ReefAPI key, one shared credit pool, the standard envelope.

Questions developers ask before integrating
What is the Company Intelligence API API?
Company Intelligence API API is a ReefAPI endpoint group for company intelligence api It returns live JSON through POST requests under /enrich-company/v1.
Is the Company Intelligence API API free to try?
Yes. ReefAPI starts with 1,000 free credits, no card required. Company Intelligence API calls use the same shared credit balance as every other ReefAPI engine.
Do I need a Company Intelligence API login or account?
No login to Company Intelligence API is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.
How fresh is the Company Intelligence API data?
The page example is captured from a live company_domain call, and production requests fetch live data through ReefAPI rather than a static sample.
How many credits does the Company Intelligence API API use?
Company Intelligence API actions currently cost 6-24 credits per successful call. Failed or blocked calls are free, and all APIs draw from one credit pool.
Can I call Company Intelligence API from an AI assistant or MCP client?
Yes. Connect ReefAPI once through MCP and your assistant can call enrich-company actions with the same key, credit pool and JSON envelope used by normal REST requests.
Is the Company Intelligence API API a Company Intelligence API scraper?
It is the managed alternative to a DIY Company Intelligence API scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same company intelligence api back as clean JSON.
Why does my Company Intelligence API scraper keep getting blocked?
Most Company Intelligence API scrapers break on anti-bot defenses, rate limits and IP bans that need rotating residential proxies and browser fingerprinting to clear. ReefAPI handles all of that for you — no proxies, no captchas, no maintenance — and returns live JSON. Blocked or failed calls are free.
