What problem does it solve?
It helps you avoid inconsistent endpoints, ambiguous schemas, and brittle error handling by providing a practical, standards-based approach to API design.
Core Features & Use Cases
- REST endpoint design: Apply resource naming, nesting rules, and HTTP method semantics to keep APIs predictable.
- API behavior contracts: Define pagination, filtering, sorting, and versioning strategies that scale as usage grows.
- Production-ready reliability: Standardize authentication, status codes, and error response structure (including request traceability).
- Documentation requirements: Produce an OpenAPI 3.x spec and validate it in CI for consistent, discoverable interfaces.
- Use Case: Design a public API for an e-commerce service where clients need stable versioning, cursor pagination, and clear error codes for storefront and admin apps.
Quick Start
Ask: Design a REST v1 API for managing orders with cursor pagination, filtering by status and date, JWT auth, and a consistent error schema with request_id.
