API overview

ErrorDX exposes one REST API (/api/v1) plus three surface flavors of it:

• Sentry-compatible ingestion at /api/:projectId/store/ and /api/:projectId/envelope/ (also /api/0/ for sentry-cli).
• MCP at POST /mcp (streamable HTTP, 21 tools) for agent clients.
• OpenAPI 3.1 at /openapi.json (public) and /api/v1/openapi.json (authenticated) for generated clients.

The errordx CLI wraps the same REST API — see Agents & CLI.
