Harbilo API

Full API. Bring your own AI agent: connect ChatGPT, Claude, Gemini, Cursor, LangChain, n8n or any agent to Harbilo's data and tools. Versioned at /v1 and documented with OpenAPI.

Updated

What it covers

  • Companies, people and business events, with the same filters as the app
  • Hot leads ranked for a workspace, with the reasons and evidence behind each score
  • Domain search, email finder, email verifier and phone finder, with evidence labels
  • Lists, saved searches, alerts, webhooks and bulk jobs
  • Self-serve account, plan, credits and API keys

Use it from any AI agent

Connect ChatGPT, Claude, Gemini, Cursor, Copilot, LangChain, n8n, Zapier or your own agent: MCP clients get every capability as a tool, and code calls the REST endpoints directly. Setup for each client is on the docs page.

Authentication

Create a key in the app under API keys, then send it as a bearer token. Paid calls take an Idempotency-Key header so a retry never charges twice.

curl -H "Authorization: Bearer hb_live_…" \
