Machine discovery for ProtoPM's public HTTP surface — health checks, free construction PDF widgets, and feature-request intake. Use this page with the OpenAPI document and the RFC 9727 API catalog.

Discovery

API catalog (RFC 9727): https://www.protopm.app/.well-known/api-catalog
OpenAPI: https://www.protopm.app/openapi.json
Health: https://www.protopm.app/api/health

Public endpoints

These routes do not require a signed-in session. PDF widgets are rate-limited and quota-gated. Prefer the HTML forms for people; use the JSON APIs for automation.

GET /api/health — liveness and database probe
GET /api/tools/quota — remaining free-widget PDF quota
POST /api/tools/invoice-pdf — construction invoice PDF (/tools/invoice)
POST /api/tools/status-report-pdf — status report PDF (/tools/status-report)
POST /api/support/feature-request — email a feature request (/support)

Authenticated app APIs
