Its AgentSource API is a single external-data and enrichment platform - one API plus a native MCP server - that resolves, fetches, enriches, and monitors a business dataset of 150M+ companies and a prospect dataset of 800M+ people aggregated from 100+ external sources. Capabilities include entity matching, filtered fetch and market-sizing stats, autocomplete, 30+ firmographic / technographic / financial / prospect-contact enrichment endpoints (single and bulk up to 50 records), real-time business and prospect event tracking with webhooks, and a shared credit pool that meters all usage. The API is hosted at https://api.explorium.ai, authenticated with an API_KEY header, and gated behind an Explorium account with a free 100-credit developer tier. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Data Enrichment - Web Intelligence - Reference Data - B2B Data - Company Data - AI Agents - Prospect Enrichment - Firmographics - MCP created: '2026-07-11' modified: '2026-07-11' specificationVersion: '0.19' apis: - aid: explorium:explorium-business-enrichment-api name: Explorium Business Enrichment API tags: - Data Enrichment - Web Intelligence - Company Data - Firmographics - Technographics - B2B Data image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://developers.explorium.ai/reference/businesses_api baseURL: https://api.explorium.ai properties: - url: https://developers.explorium.ai/reference/businesses_api type: Documentation - url: https://developers.explorium.ai/reference/fetch_businesses type: APIReference - url: openapi/explorium-openapi.yml type: OpenAPI description: >- Fetch, market-size (stats), and enrich company records across 150M+ businesses.
