API Development
Reliable REST and GraphQL APIs with auth, docs, and operational baselines.
API design and implementation for product, partner, and internal consumers. We define contracts, authentication, rate limits, and documentation so integrators know what to expect—and we wire enough observability that latency and error budgets are visible after launch.

Who it’s for
- • Platform teams exposing partner or public APIs
- • Product companies splitting client and server contracts
- • B2B teams needing stable integration surfaces
Problems we address
- • Ad-hoc endpoints without versioning or docs
- • Auth and rate limits inconsistent across routes
- • Integrators reverse-engineer behavior from production traffic
Expected outcomes
- • Intentional API surface with versioning strategy
- • Auth, validation, and rate-limit defaults
- • OpenAPI (or GraphQL schema) as the source of truth

FAQ
Depends on client needs and caching model. We recommend REST for many public/partner APIs and GraphQL when clients need flexible graphs over shared domain data.
Docs and examples are included in API Foundation. A full branded developer portal can be scoped as an extension.
