# Captain Data

> AI Data for AI Products. Captain Data provides a REST API for fresh B2B people and company data — enrichment, search, and discovery — built for product teams, GTM platforms, and AI agents. Base URL `https://api.captaindata.com/v1`, authenticated with an `X-API-KEY` header. Free trial: 100 credits (one-shot), no credit card.

Captain Data helps you understand people and companies with real-time, structured profiles. Pass a LinkedIn URL, a name, a company, or a Sales Navigator–compatible search query; get JSON you can ship in products, workflows, and agents.
