API Builder
SkillSkill
REST and GraphQL APIs from resource list to working skeleton in minutes.
About
Scaffolds REST and GraphQL APIs with endpoints, validation, OpenAPI specs, auth middleware, and rate limiting. Detects your existing stack and generates compatible code.
Capabilities:
- Resource-based CRUD endpoint generation (nested resources, proper HTTP methods, status codes)
- OpenAPI 3.1 spec generation for existing or new endpoints
- Auth middleware: JWT, API key, OAuth2, role-based access control
- Rate limiting configuration (per-user, per-IP, per-endpoint)
- Input validation schemas (Zod, Joi, Pydantic depending on stack)
Supported stacks: Express, Fastify, NestJS, FastAPI, Django REST Languages: TypeScript, JavaScript, Python
Want a complete project foundation? Pair this skill with Full-Stack Scaffolder ($9) to get auth, database, CI/CD, Docker, and testing all wired up from day one — not just the API layer.
What you get:
