  title: Explorium AgentSource Business Enrichments Businesses API
  description: The Explorium AgentSource API is a single external-data and enrichment API for AI agents and go-to-market teams. It exposes match, fetch, statistics, autocomplete, enrichment, bulk enrichment, and event/enrollment endpoints over a business dataset (150M+ companies) and a prospect dataset (800M+ people) aggregated from 100+ external sources. All endpoints are hosted at https://api.explorium.ai and authenticated with an API key sent in the API_KEY request header. Access is gated behind an Explorium account and a credit balance (a free developer tier of 100 credits is available), so this document is honestly modeled from Explorium's published OpenAPI index and reference pages - the endpoint paths and HTTP methods are confirmed from Explorium's own documentation, while request and response schemas are represented at a representative level. Not every one of the 30+ enrichment endpoints is enumerated here; a representative subset is included. endpointsModeled - request/response bodies are modeled; paths are confirmed.
