The API Development Process

APIs built for scale + developer joy.

An API is a public product. Bad APIs cost you partner integrations, developer mindshare, and support hours. We design APIs that developers want to integrate.

1

API design + contracts

Week 1

OpenAPI 3 spec, resource modeling, versioning strategy, auth + rate-limiting policy, error-code taxonomy, response-envelope conventions.

2

Build + test

Week 2-4

Implementation in Node.js / Python / Go, type-safe with Zod / Pydantic validation, pgsql + Redis, contract tests via Pact, unit + integration coverage.

3

Docs + SDKs

Week 5

Auto-generated docs from OpenAPI (Mintlify / Readme), SDK generation for JS / Python / Ruby, Postman collection, interactive API explorer.

4

Launch + observe

Week 6+

Datadog + Sentry + OpenTelemetry, per-endpoint SLOs, alerting, on-call rotation, error budgets tracked weekly.

What&apos;s Included

Everything to ship + operate an API.

Design, docs, SDKs, observability, security, and versioning — one team handles all of it.

01

OpenAPI 3 spec + design

Complete API contract in OpenAPI format, versioned in Git, used to generate docs + SDKs + mocks. Spec-first development — no “docs coming soon” nonsense.

02

Auto-generated docs + SDKs

Mintlify or Readme docs regenerated on spec changes. SDKs in JavaScript / Python / Ruby auto-generated and published to npm / PyPI / RubyGems.

03

Auth + security

OAuth 2.0, API keys, JWT, or mTLS — depending on your product. Rate limiting, quota management, threat detection, OWASP API Security Top 10 compliance.

04

Observability + SLOs

Datadog / Honeycomb distributed tracing, per-endpoint latency + error-rate dashboards, SLO + error budget tracking, on-call rotation.

Who Needs Custom APIs

Built for companies treating their API as a product.

Internal-only CRUD APIs can be boilerplate. Public APIs are a brand — and a support surface. We build the second kind right.

Platform + SaaS

Customer-facing APIs, partner integrations, marketplace plugins. Your API is your platform's product surface — treat it like one.

Fintech + Banking

Open banking, payment APIs, KYC verification, BaaS. Heavy compliance: PCI DSS, SOC 2, ISO 27001. We ship audit-ready.

Commerce + Retail

Inventory APIs, order-management integrations, dropship + 3PL sync. B2B ecommerce is API-first by default; your partners expect clean endpoints.

Healthcare + EHR

FHIR + HL7 integrations, HIPAA-compliant patient data, insurance verification. Regulatory-grade security + data-residency requirements.

Our API Stack

Best-in-class tools for API design + ops.

Spec-first, automation-heavy, observability-rich API infrastructure.

API development, answered honestly.

REST vs. GraphQL vs. gRPC?

REST for public APIs + simple CRUD — easiest to learn, most tooling. GraphQL for frontend-owned APIs with rich query needs. gRPC for internal microservice communication at scale. We pick per endpoint, not per platform.

How do you version APIs?

URL-based versioning (`/v1/`, `/v2/`) for breaking changes, header-based for minor variations. Backward-compatibility guarantees for 12 months minimum. Deprecation notices 6 months in advance.

What about rate limiting?

Per-key + per-IP + per-endpoint. Redis-backed counters, X-RateLimit-* headers, 429 responses with Retry-After. Quota tiers configurable per API key for freemium + paid plans.

How do you handle auth?

OAuth 2.0 (Authorization Code + PKCE) for user-facing APIs. API keys + HMAC signing for machine-to-machine. JWT for session-like 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 with zero breaking changes. Typical timeline: 3-6 months depending on endpoint count.

Fair pricing for serious APIs.
