Custom APIs
APIs that integrate, scale and stay documented.
REST and GraphQL services your team and partners can rely on — with proper auth, versioning, observability and SLAs from day one.
The problem
What we're solving
Most internal APIs grow like weeds: undocumented, inconsistent, brittle. Integrations break in production, partners can't onboard, and on-call rotates through bug fixes instead of features. Good API design is a discipline — and it pays back forever.
Our approach
How we deliver
- Design-first: contracts and schemas before code.
- Versioning and deprecation policies you can actually live with.
- Auth, rate-limiting and observability baked in.
- Docs your partners will read — and use.
What you get
Deliverables
- ✓REST or GraphQL service with OpenAPI/SDL spec
- ✓Auth (OAuth, JWT, API keys) and rate-limiting
- ✓Generated client SDKs (TypeScript, Python)
- ✓Hosted developer portal with examples
- ✓Observability: metrics, traces, alerts
- ✓Versioning and deprecation playbook

In practice
Use cases
Partner integrations
Public APIs that third parties can ship against without hand-holding.
Mobile/web backends
Type-safe APIs that frontend teams love working with.
Service decomposition
Carving the right services out of a monolith — without breaking it.
FAQ
Common questions
REST or GraphQL?+
Depends on the consumers. We pick what's right for the team using it, not what's trendy.
Do you handle migrations from existing APIs?+
Yes — including dual-running, version negotiation and partner migration.
What about SDKs?+
We generate them from the spec so they never drift. We can publish them to npm/PyPI under your namespace.
How do you guarantee uptime?+
SLAs are part of the retainer. We define them with you and report against them monthly.
