  title: Explorium AgentSource 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.
