See the full documentation →Ways to integrate
Zapier & no-code
Point any OpenAPI-aware tool at /openapi.json. For "something new" triggers use the /api/v1/*/changes endpoints.
Webhooks
Subscribe an HTTPS URL to receive push events: a new matching tender, a new anomaly, a new award. HMAC-signed.
MCP server
Connect the API to Claude or other MCP clients with the official package, authenticated with your API key.
