Which Company API Should an Agent Use?
Company workflows succeed or fail on identifier quality. Prefer durable identifiers like company domains or company social media URLs, and use this routing table before chaining multiple company endpoints together.
| Goal | Recommended API | Why |
|---|---|---|
| Find companies by market criteria | Company Search | Best when your starting point is industry, location, website keyword, or market filters. |
| Enrich a known company from domain or company social media URL | Company Enrichment | Best when you already have a durable identifier and want firmographics or profile data. |
| Retrieve public employee profiles for a known company | Company Employees | Best when you have a company name, domain, or company social media URL and want a structured list of associated public profiles. |
| Find ranked ICP candidates with demonstrated similar-product interest | Company Intent | Best when you want people who have shown interest in similar products, ranked by fit for an ICP company domain. |
| Find company-level engagement signals | Company Competitor Engagements | Best when you have a company page URL and want related engagement items with content and aggregate engagement details. |
| Summarize challenges from filings | Company Needs | Best for business pain points and challenge framing rather than profile data. |
| Retrieve funding rounds and investors | Company Funding | Best for capital history, investors, and valuation context. |
| Find companies from the open web with source-backed evaluation | Discovery API | Best when you need open-web discovery with requirements, extractions, and citations. |
| Check if the company sells a product or service | CheckSeller | Best for seller verification and qualification workflows. |
| Check website technology or stack signals | Feature Checker | Best for technology qualification and website feature detection. |
| Look up investors or funds directly | Investor Lookup | Best when the target is the investor, not a company they funded. |
