API Surface and Contract Management

Epic: REST API Design and Implementation

Plan: Build a versioned REST API (/v1) that exposes Members, Quotes, and Bookings endpoints with cursor-based pagination. The API is the external contract for all consumers.

Architectural Context: The REST API sits behind the Gateway Foundation and uses the same connector abstraction. All endpoints follow consistent patterns: versioned paths, cursor-based pagination, and uniform error responses. The API is the primary interface for external systems integrating with the platform.

Tasks

• Implement versioned REST API with /v1 prefix
• Build Members endpoint (GET /v1/members/:externalId)
• Build Quotes CRUD (POST/GET/PATCH/DELETE /v1/quotes)
• Build Bookings CRUD (POST/GET/PATCH/DELETE /v1/bookings)
• Implement health endpoint (GET /v1/healthz)
• Implement cursor-based pagination for list endpoints

Epic: API Documentation

Plan: Generate and serve an OpenAPI 3.x specification for all endpoints, with JSON Schema validation for all inputs. Documentation is served at /v1/docs.

Architectural Context: OpenAPI spec is generated from code annotations, ensuring docs stay in sync with implementation. JSON Schema validation rejects unknown fields and oversized payloads at the gateway layer, before they reach connectors.

Tasks

• Generate OpenAPI 3.x spec for all endpoints
• Serve documentation at /v1/docs
• Implement JSON Schema validation for all inputs
