Leading REST API Development TeamREST API
We build production-grade REST APIs that serve millions of requests per day. Fixed price, 8-12 week delivery, senior engineers only.
IRPR is a leading REST API development team that builds scalable, secure, and well-documented APIs using Node.js, Python, Go, and .NET Core. We design RESTful endpoints with OpenAPI 3.0 specs, JWT authentication, rate limiting, and automated testing from day one.
Every REST API ships with a CI/CD pipeline, Postman collections, Swagger docs, and a fixed price quote in the Roadmap phase. Typical projects run 8-12 weeks and cost between $80K and $250K depending on complexity. We support HIPAA, PCI-DSS, and SOC 2 compliance out of the box.
CTOs at Series A startups hire us to replace legacy SOAP APIs with modern REST backends. Product managers at healthcare platforms need HIPAA-compliant patient data APIs. Engineering leads at fintech companies require PCI-DSS certified payment APIs. We serve all of them with the same senior-only team.

Why Choose a Leading REST API Development Team
A well-designed REST API is the backbone of every modern application. Here is what IRPR delivers.
IRPR has shipped over 200 products across 50+ countries, each with a custom REST API built by senior engineers. Our APIs handle authentication, rate limiting, caching, and error handling by default. We use OpenAPI 3.0 for documentation and Postman collections for testing.
Every API we build includes automated CI/CD pipelines on GitHub Actions, monitoring with Datadog or Sentry, and a 99.9% uptime SLA. We support compliance standards like HIPAA, PCI-DSS, and SOC 2. You get the source code, the docs, and the infrastructure scripts.
The IRPR Difference vs Generic API Shops
Not all REST API teams are equal. Here is how IRPR stands out from generic development shops.
Generic shops often assign junior developers to API projects. They skip documentation, ignore rate limiting, and deliver unsecured endpoints. You end up with technical debt and rework costs.
IRPR assigns senior engineers only. Every API includes OpenAPI specs, automated tests, security audits, and deployment scripts. We give you a fixed price in week 2, not an hourly estimate that changes every month.
- Junior or offshore developers
- No OpenAPI documentation
- No rate limiting or caching
- No security audit
- Hourly billing with scope creep
- No post-launch monitoring
- Senior engineers with 10+ years experience
- OpenAPI 3.0 docs generated automatically
- Rate limiting, caching with Redis, and pagination
- OWASP security audit in every sprint
- Fixed price quoted in Roadmap phase (week 2)
- Datadog monitoring and 99.9% uptime SLA
How We Build Your REST API
Our process from idea to production API takes 8-12 weeks. Here are the four phases.
Every project starts with a Roadmap phase where we define endpoints, data models, and integration points. You get a fixed price and timeline before any code is written.
During the Product phase, we build the API in 2-week sprints. You see working endpoints every sprint. We deploy to staging, run load tests, and hand over the source code at the end.
What Ships With Every REST API
Every REST API from IRPR includes these deliverables by default. No hidden extras.
You get more than just endpoints. Every project ships with documentation, infrastructure, and monitoring tools. You can deploy and maintain the API yourself or let us handle it.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (Swagger UI)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Docker containers for local development
- Redis caching layer for high-traffic endpoints
- Rate limiting and authentication (JWT or OAuth2)
- Error logging with Sentry
- Uptime monitoring with Datadog
- Deployment playbook for AWS, GCP, or Azure
