Why You Need a Leading REST API Development Partner
A well-designed REST API is the backbone of every modern web and mobile application.
IRPR has shipped 200+ REST APIs for clients in 50 countries. Our APIs handle everything from 1,000 to 10 million requests per day. We use OpenAPI 3.0 for documentation, Postman for testing, and Datadog for monitoring.
Every REST API we build includes rate limiting (e.g., 1000 req/min), JWT authentication, and automated CI/CD pipelines. We deploy on AWS ECS, Google Cloud Run, or Azure App Service. Our average API response time is under 50ms.
Generic Dev Shop vs IRPR
Not all REST API development partners deliver the same quality, speed, or security.
Many agencies build REST APIs without proper documentation or testing. They use outdated frameworks and skip security audits. You end up with a slow, buggy API that costs more to fix than to rebuild.
IRPR follows a strict process: OpenAPI spec first, then code, then automated tests. Every API gets a security review, load test, and deployment guide. We deliver on time and on budget.
- No OpenAPI spec before coding
- No automated testing
- No rate limiting or throttling
- No security audit
- No deployment pipeline
- Hourly billing with scope creep
- OpenAPI 3.0 spec approved before coding
- 100% test coverage on critical endpoints
- Rate limiting and DDoS protection built in
- HIPAA/PCI/SOC 2 security review included
- CI/CD pipeline with GitHub Actions
- Fixed price, no surprises
Our REST API Development Process
We follow a four-phase process to deliver your REST API in 8-12 weeks.
Phase 1: We define the API endpoints, data models, and authentication flow in an OpenAPI 3.0 spec. You review and approve the spec before any code is written.
Phase 2: We build the API in weekly sprints. Each sprint ends with a deployable version. You see progress every Friday.
What Ships with Your REST API
Every REST API project includes these deliverables by default.
You get full ownership of the source code, documentation, and deployment scripts. No black boxes, no hidden dependencies.
IRPR provides a complete handoff package so your team can maintain the API from day one.
- OpenAPI 3.0 spec file (YAML/JSON)
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Postman collection with example requests
- Unit tests (100% coverage on critical endpoints)
- Load test results (e.g., 10,000 req/s)
- Security audit report
- Deployment guide for AWS/GCP/Azure
- Sentry error tracking setup
- Datadog monitoring dashboard

Why teams hire us.
Fixed price, not hourly
Every REST API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
Every engineer on your project has 7+ years of experience building REST APIs. No junior developers, no offshore outsourcing. Your API is built by someone who has shipped 20+ production APIs.
OpenAPI spec first
We design the entire API in an OpenAPI 3.0 spec before coding. You review and approve every endpoint, every schema, every error code. No surprises during development.
Security built in
Every REST API includes JWT authentication, rate limiting, input validation, and OWASP Top 10 protections. For regulated industries, we add HIPAA, PCI-DSS, or SOC 2 compliance checks.
8-12 week delivery
Your first production-ready REST API ships in 8-12 weeks. We use weekly sprints and continuous deployment. You see working code every Friday.
Full code ownership
You own 100% of the source code, documentation, and deployment scripts. No licensing fees, no vendor lock-in, no restrictions. Your API is yours forever.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
