REST API

All integrations are built on the same REST API available to SDKs and the MCP server. For direct API access:

  • API Reference — Complete endpoint documentation
  • OpenAPI Spec — Machine-readable OpenAPI 3.0 specification
  • SDKs — Official client libraries (JavaScript, Python, Go, PHP)
  • MCP Server — 131 tools for AI agents

Building Custom Integrations

The REST API and OpenAPI spec make it straightforward to build integrations for any platform:

  1. Get an API key — Sign up and generate a pk_live_* key from the dashboard
  2. Use the OpenAPI spec — Import https://api.proof.holdings/api/openapi.json into your platform's API connector
  3. Authenticate — Pass the API key as Authorization: Bearer pk_live_...
  4. Test with test mode — Use a pk_test_* key during development — no real messages sent, no quota consumed
