API Development for
Speed, Security, and Scale.
REST, GraphQL, or gRPC — we build APIs that handle 10M+ daily requests at sub-50ms p99 latency. Auto-documented, rate-limited, secured from day one.
Production-ready from day one.
Auth + Security
OAuth 2.0, JWT, mTLS, rate limiting, DDoS protection
Auto Documentation
OpenAPI/Swagger, Postman collections, SDK generation
Caching Layer
Redis caching, CDN for static responses, edge functions
Monitoring
Datadog APM, error tracking, latency alerts, dashboards
Webhooks
Incoming handlers, outgoing with retries, admin UI
Testing
90%+ test coverage, load testing, chaos testing
“Our old API maxed at 500 RPS. Maple54's rebuild handles 12K RPS at 34ms p99. Zero downtime in 14 months. Better than AWS internal APIs.”
APIs developers want to integrate.
An API is a public product. Bad APIs cost you integrations, developer mindshare, and support hours. We design APIs developers love — so your platform wins.
API design + contracts
Week 1OpenAPI 3 spec, resource modeling, versioning strategy, auth + rate-limit policy, error-code taxonomy, response-envelope conventions.
Build + test
Week 2-4Implementation in Node.js / Python / Go, Zod / Pydantic validation, PostgreSQL + Redis, contract tests via Pact, 90%+ coverage.
Docs + SDKs
Week 5Mintlify / Readme docs auto-generated from OpenAPI, SDK generation for JS / Python / Ruby, Postman collection, interactive API explorer.
Launch + observe
Week 6+Datadog + Sentry + OpenTelemetry, per-endpoint SLOs, alerting, on-call rotation, developer-feedback loop.
Everything to ship + operate an API.
Design, docs, SDKs, observability, security, and versioning — one team handles all of it.
OpenAPI 3 spec + design
Complete API contract in OpenAPI, versioned in Git, used to generate docs + SDKs + mocks. Spec-first development — no “docs coming soon.”
Docs + SDKs auto-generated
Mintlify or Readme docs regenerated on spec changes. SDKs in JS / Python / Ruby auto-published to npm / PyPI / RubyGems.
Auth + security
OAuth 2.0, API keys, JWT, or mTLS. Rate limiting, quota management, threat detection, OWASP API Security Top 10 compliance.
Observability + SLOs
Datadog / Honeycomb distributed tracing, per-endpoint latency + error-rate dashboards, SLO + error-budget tracking, on-call rotation.
Built for companies treating APIs as products.
Internal CRUD APIs can be boilerplate. Public APIs are a brand — and a support surface. We build the second kind right.
Platform + SaaS
Customer APIs, partner integrations, marketplace plugins. Your API is your platform's product surface — treat it like one.
Fintech + Payments
Open banking, payment APIs, KYC verification. PCI DSS + SOC 2 compliance baked in.
Commerce + B2B
Inventory APIs, order-management integrations, 3PL sync. B2B commerce is API-first — partners expect clean, stable endpoints.
Healthcare + EHR
FHIR + HL7 integrations, HIPAA-compliant patient data APIs, insurance verification. Regulatory-grade security.
Boring technology. Exciting outcomes.
Deliberately narrow, battle-tested stack — same tooling that powers Shopify, Notion, Linear, and Vercel.
API development, answered honestly.
REST vs. GraphQL vs. gRPC?
REST for public APIs + simple CRUD. GraphQL for frontend-owned APIs with rich queries. gRPC for internal microservices at scale. We pick per endpoint, not per platform.
How do you version APIs?
URL-based (`/v1/`, `/v2/`) for breaking changes. Backward-compatibility guaranteed 12 months. Deprecation notices 6 months ahead.
What about rate limiting?
Per-key + per-IP + per-endpoint. Redis-backed counters, X-RateLimit-* headers, 429 responses. Quota tiers configurable for freemium + paid plans.
How do you handle auth?
OAuth 2.0 (Authorization Code + PKCE) for user APIs. API keys + HMAC signing for M2M. JWT for session flows. mTLS for high-security enterprise partners.
Can you migrate our legacy API?
Yes. Incremental migration via API gateway + strangler-fig pattern. Legacy + new APIs coexist during transition, partners migrate endpoint-by-endpoint without breaks.
