Frequently Asked Questions
What data does the Company Enrichment API return?
The API returns 700+ signals per domain including financials (revenue, funding, SEC filings), workforce data (headcount, hiring velocity, department breakdown), website intelligence (site content and technology updates), social activity (LinkedIn posts, engagement), leadership changes, product launches, and market signals.
How fresh is the company enrichment data?
Signal freshness varies by type. Social activity and hiring signals refresh daily. SEC filings update within 24 hours of EDGAR publication. Firmographic data refreshes weekly. All timestamps are included in the response so you know exactly when each signal was last observed.
How much does enrichment cost?
2 credits per signal returned, billed per row. Use the signal_types and limit parameters to control how many signals come back. Responses with zero results are never charged, and credit usage is returned in response headers on every call.
What format does the API use for authentication?
Pass your API key in an X-API-KEY header, or as Authorization: Bearer <key>. You can generate your API key from the developer portal at signalapi.autobound.ai. No OAuth flow required.
