API development

REST + GraphQL, OpenAPI, versioning, rate limiting

APIs for external clients, mobile apps, B2B partners. Properly documented, versioned, with multi-strategy authentication and rate limiting from day one.

What we ship
  1. 01

    REST + GraphQL API design

    REST where simplicity matters, GraphQL for complex queries with n+1 avoided. Pydantic / Zod models as the source of the contract.

  2. 02

    Auto-generated OpenAPI documentation

    Swagger UI / Redoc / Scalar generated from code. Error codes, examples and schema stay current, not out of sync.

  3. 03

    Proper versioning (v1, v2)

    Deprecation policy with sunset headers, migration guides, overlap period. Clients know before anything breaks.

  4. 04

    Rate limiting + caching

    Sliding window per API key or per IP. Redis cache for hot read endpoints. CDN-level caching where possible.

  5. 05

    Multi-strategy auth

    JWT RS256 for SPAs, API keys for B2B integrations, OAuth2 for third-party apps. Refresh tokens with rotation.
