Best REST API Development StudioDevelopment Studio
We build REST APIs that ship in 12 weeks. Fixed price, senior engineers, full ownership.
IRPR is the best REST API development studio for companies that need production-grade APIs fast. We use Node.js, Python, Go, and PostgreSQL to build RESTful APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box. You get full source code ownership and a CI/CD pipeline on GitHub Actions.

Why IRPR is the Best REST API Development Studio
We have shipped over 200 REST APIs for clients in 50 countries. Here is what that experience looks like in numbers.
Every REST API we build goes through a structured process: design, prototype, build, test, deploy. We use OpenAPI 3.0 for specification, Postman for testing, and Datadog for monitoring.
Our APIs average 99.9% uptime and handle 10,000+ requests per second. We document every endpoint with Swagger UI and provide SDK examples in Python, JavaScript, and curl.
Generic Dev Shop vs the Best REST API Development Studio
Not all API development teams are the same. Here is how IRPR compares to a generic dev shop.
Generic dev shops often deliver REST APIs that are slow, undocumented, and hard to maintain. They use hourly billing and change scope mid-project.
IRPR delivers production-grade REST APIs with OpenAPI specs, automated tests, and CI/CD pipelines. We quote a fixed price in week 2 and never change it.
- Hourly billing with no cap
- No API documentation
- No automated tests
- No CI/CD pipeline
- No monitoring or alerts
- No compliance support
- Fixed price from week 2
- OpenAPI 3.0 spec included
- 100% test coverage on endpoints
- GitHub Actions CI/CD
- Datadog monitoring + PagerDuty alerts
- HIPAA, PCI-DSS, SOC 2 ready
How We Build Your REST API in 12 Weeks
Our process is designed to get you a working API fast, with no surprises.
We start with a 2-week Roadmap phase where we define endpoints, data models, and authentication. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints. You see working endpoints every sprint. We deploy to staging in week 6 and production in week 10. Week 12 is for load testing and documentation.
What Ships with Every REST API
Every project includes these deliverables by default. No hidden extras.
You get everything you need to run, maintain, and scale your API. No vendor lock-in, no recurring fees.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Docker containers for local development
- Sentry error tracking
- Datadog monitoring dashboard
- Load test report (10,000+ req/s)
- Deployment runbook
- 1 hour of post-launch support

Our team averages 10+ years of experience. Every engineer has shipped production REST APIs at scale. No junior developers, no offshore outsourcing, no handoffs between teams.
Full code ownership
You own 100% of the source code, documentation, and infrastructure. No proprietary frameworks, no license fees, no vendor lock-in. We hand over everything in your GitHub repo.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant REST APIs by default. Our infrastructure uses encrypted storage, audit logging, and role-based access control. No bolt-on security.
