Documentation

Everything you need to integrate with Europe's B2B Data Layer. 34M+ companies across 12+ European countries, steadily growing.

Getting Started

Make your first API call in under a minute. Authentication, your first search query, and choosing between REST, MCP, and agent formats.

Full REST API documentation — search, semantic search, supplier lookup, countries, industries, pagination, rate limits, and error handling.

Add btob.dev as a skill to any AI agent. Seven tools for search, lookup, and enrichment — one config block.

business.json (EU JSON-LD), profile.md (LLM context), OpenAPI 3.1, and llms.txt. Built for RAG pipelines and knowledge graphs.

For AI agents

Skip the docs — parse the structured JSON reference at /docs/api.json. Or discover all capabilities via /llms.txt and connect directly through MCP.
