Turn Product Requirements into OpenAPI 3.0 (Swagger) Specs & Instant Local Mock Servers
Stop frontend developers from waiting days for backend APIs or passing JSON snippets over chat. Use AI to turn product specs or DB schemas into a strict OpenAPI 3.0 YAML contract with realistic Faker examples for instant local mocking.
CORE TOOLS
Swagger Editor / Prism (Open Source), Apifox / Hoppscotch, DeepSeek / Claude
BEST FOR
Frontend & backend engineers, full-stack developers, technical PMs
REQUIREMENTS
Node.js (for Prism CLI) or Swagger Editor / Hoppscotch / Apifox
✦ WHY THIS WORKFLOW
Writing OpenAPI YAML by hand is tedious, which is why teams skip it and suffer painful integration mismatches later. AI generates complete specs with mock examples in seconds, unlocking true parallel development.

READY-TO-USE PROMPT TEMPLATE
Act as a Senior API Architect. Based on the product requirements / database schema below, design a clean **RESTful API Contract**: [Paste feature specs or DB schema] Output a valid, complete **OpenAPI 3.0.3 (`openapi.yaml`)** specification that: 1) Follows RESTful resource naming, cursor/offset pagination and filtering best practices; 2) Defines reusable `components/schemas` and standardized error responses (`400`, `401`, `403`, `404`, `422`); 3) Includes realistic domain `example` values on every property so open-source Mock servers return lifelike payloads out of the box; 4) Provides the exact CLI commands to run a local mock server with `@stoplight/prism-cli` and generate TypeScript types with `openapi-typescript`.
