Your Affordable REST API Development PartnerREST API
We build production-grade REST APIs in 8-12 weeks. Fixed pricing from $80K with full code ownership.
IRPR builds affordable REST APIs using Node.js, Python (FastAPI), Go, and Next.js. We design endpoints, handle authentication with JWT or OAuth 2.0, and connect to databases like PostgreSQL, MySQL, and MongoDB.
Every API ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. You get source code, CI/CD pipelines, and Postman collections on day one.
Startups hire us to build their core product API without burning runway. Enterprise teams use us to replace legacy SOAP or GraphQL services. Agencies partner with us to deliver white-label APIs for their clients.

Why an Affordable REST API Development Partner Matters
A well-designed REST API is the backbone of modern software. Here is what IRPR delivers.
IRPR has shipped over 200 REST APIs for clients in 50+ countries. Each API includes auto-generated OpenAPI 3.0 documentation, rate limiting, and health check endpoints. We use FastAPI for Python projects and Express.js for Node.js projects.
Our 8-12 week builds include load testing with k6 to handle 10,000+ requests per second. We deploy to AWS ECS or Google Cloud Run with auto-scaling. Every API gets Sentry error monitoring and Datadog metrics from day one.
The Difference Between IRPR and a Generic Dev Shop
Most agencies bill hourly and deliver late. IRPR gives you a fixed price and a firm timeline.
Generic dev shops often start with a vague estimate and bill by the hour. They use junior developers, skip documentation, and leave you with unmaintainable code. We have seen clients waste $50K on APIs that never ship.
IRPR assigns senior engineers only. Every project has a fixed quote after a 2-week Roadmap phase. Our APIs ship with OpenAPI docs, integration tests, and CI/CD pipelines. You own the code and can deploy anywhere.
- Hourly billing with no cap
- Junior or offshore developers
- No OpenAPI documentation
- No load testing or benchmarks
- No CI/CD from day one
- Code license unclear
- Fixed price after Roadmap phase
- Senior engineers only (10+ years)
- Auto-generated OpenAPI 3.0 docs
- k6 load testing at 10K+ RPS
- GitHub Actions CI/CD pipeline
- Full code ownership, no license fees
Our 4-Phase Process for Building Your REST API
From idea to production in 8-12 weeks. Here is exactly how IRPR works.
Every project starts with a 2-week Roadmap phase. We map out every endpoint, data model, and integration. You get a fixed price and a Gantt chart before we write a single line of code.
After Roadmap approval, we build the API in 6-10 weeks. We deploy to staging, run integration tests, and deliver Postman collections. Final release includes production deployment and a 30-day warranty.
What Ships with Every REST API from IRPR
Every deliverable is concrete and production-ready. No fluff.
You are not buying just endpoints. You are buying a complete system that your team can maintain and scale. IRPR includes everything listed below on every project.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (auto-generated)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Docker container with docker-compose
- Sentry error tracking and alerts
- Datadog or CloudWatch monitoring dashboard
- Load test results from k6 (10K+ RPS)
- Deployment runbook with rollback steps
- 30-day post-launch support and bug fixes

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we start building.
Senior engineers only
IRPR does not use junior or offshore developers. Every engineer on your project has 10+ years of experience building production APIs. We have shipped over 200 APIs for clients in 50+ countries.
OpenAPI docs by default
Every REST API ships with auto-generated OpenAPI 3.0 documentation. Your frontend team and third-party integrators get a working spec from day one. No manual docs that go stale.
Load tested to 10K+ RPS
We run k6 load tests on every API before staging. We fix bottlenecks and tune database queries until the API handles 10,000+ requests per second. Your API will not crash on launch day.
Full code ownership
You own every line of code. No licenses, no royalties, no vendor lock-in. We push source code to your GitHub repo from the first commit. You can deploy anywhere with any team.
30-day post-launch warranty
After production release, we provide 30 days of free bug fixes and support. We monitor Sentry errors and Datadog metrics to catch issues before you do. Your team gets a smooth handoff.
