Professional Rest API Development VendorRest API
We build production-grade REST APIs on fixed price. Ship your MVP in 8-12 weeks with full code ownership.
IRPR is a professional REST API development vendor. We build RESTful APIs with Node.js, Python, Go, and Java on AWS, Azure, or GCP. Our APIs use JSON, OAuth 2.0, and OpenAPI 3.0 for clear documentation.
We deliver a working API in 12-14 weeks for $80K-$200K. Every project includes a Roadmap phase where we lock scope, architecture, and price. We handle compliance: HIPAA, PCI-DSS, SOC 2, and FERPA.
CTOs upgrading from monolithic apps hire us for a scalable REST API. Product teams shipping a SaaS MVP use our APIs for user management and billing. Healthcare platforms need HIPAA compliant REST APIs for patient data exchange. Fintech startups need PCI-DSS APIs for payment processing.

What A Professional REST API Development Vendor Delivers
We ship a complete, secure, and documented REST API that your frontend or third-party apps can call immediately.
A professional REST API from IRPR includes versioned endpoints, rate limiting, and authentication via OAuth 2.0 or JWT. We generate interactive API docs with Swagger UI so your team can test endpoints before we hand over the repo. Every API is deployed on AWS Lambda or EC2 with auto-scaling and CloudWatch monitoring.
Our REST APIs handle 10,000+ requests per second through load balancers and Redis caching. We write unit and integration tests with Jest and Postman. Your codebase is 100% yours from day one, stored in a private GitHub repo with CI/CD and Sentry error tracking.
Why Hire IRPR As Your REST API Vendor
Generic dev shops deliver half-broken APIs with no docs and no tests. IRPR gives you a production-ready API with full ownership.
When you hire a professional REST API development vendor, you expect a secure, documented, and scalable API. Most agencies hand over a set of endpoints with no versioning and no error handling. You end up spending weeks fixing basic issues before you can launch.
IRPR treats your API as a product. We design endpoints that match your business domain, write OpenAPI specs before writing code, and deploy with automated CI/CD. We ship the source code, tests, deployment scripts, and monitoring dashboards in a single handoff.
- No API schema before coding
- Authentication is an afterthought
- No rate limiting or throttling
- Manual deployment to a single server
- No error handling or status codes
- No documentation or postman collection
- OpenAPI 3.0 spec written in week 1
- OAuth 2.0 or JWT from day one
- Rate limiting with Redis and Cloudflare
- CI/CD to AWS or GCP with auto-scaling
- Consistent error responses with RFC 7231 codes
- Auto-generated Swagger docs and Postman collection
How IRPR Builds Your REST API In 5 Phases
We follow a structured process from idea to deployment so you never get surprised by scope or cost.
Every project starts with a Roadmap phase (week 1-2). We map every endpoint, define the data model, choose the tech stack, and set the fixed price. No open-ended discovery, no time and materials trap. You approve the Roadmap and we start building.
From week 3 to week 12, we build the API in two-week sprints. You see working endpoints every Friday with automated tests and documentation. We deploy to a staging environment for your team to test. The last week is production deployment and handoff training.
