Expert REST API Development ServicesREST API
Build secure, scalable REST APIs that connect your systems. 200+ APIs delivered in 12 weeks or less.
We build expert REST API development services for companies that need reliable, secure, and fast data exchange between systems. Our APIs are built with Node.js, FastAPI, or Django REST Framework, backed by PostgreSQL and Redis.
Every project ships with an OpenAPI specification, automated tests, and CI/CD pipelines. Delivery in 8-12 weeks. Fixed pricing from $80K to $250K. Compliance options include HIPAA, PCI-DSS, and SOC 2.
Founders building SaaS products that need a public API from day one. CTOs migrating from monolithic to microservices with REST interfaces. Product managers integrating third-party APIs like Stripe or Salesforce. Enterprise teams requiring custom APIs for internal tooling.

Why expert REST API development matters for your business
A well-designed REST API is the foundation for modern software integration.
A poorly built API slows down development, creates security holes, and frustrates users. IRPR builds APIs that are fast, secure, and documented from day one. Our team of senior engineers has shipped 200+ REST APIs across 50 countries.
Each API is designed with OpenAPI 3.0, tested automatically, and deployed with CI/CD. We ensure 99.9% uptime through monitoring and load testing. Your team gets a reliable, scalable API that integrates with any system.
Generic dev shop vs IRPR for REST API projects
Not all development teams deliver the same quality. Here is how IRPR stands out.
Many development shops promise a REST API but deliver half-baked code with no documentation and missing security. They often bill hourly, leaving you with uncertain costs and timelines.
IRPR works differently. We fix the price, the spec, and the deadline in the Roadmap phase. You get a production-ready API with full documentation, automated tests, and compliance baked in.
- No fixed price - hourly billing with budget overruns
- Unclear specification - vague requirements lead to rework
- Little compliance experience - HIPAA/PCI rarely handled
- Slow iterations - no structured sprints or CI/CD
- Poor documentation - no OpenAPI spec or Postman collection
- No post-launch support - you are on your own after delivery
- Fixed price from Roadmap - no surprises, no scope creep
- OpenAPI spec from day one - clear, documented interface
- HIPAA/PCI experience - 50+ compliance projects delivered
- 2-week sprints with CI/CD - visible progress every sprint
- Automated documentation - always up-to-date Swagger UI
- 1 year post-launch support - bug fixes and monitoring included
Our process for building your REST API
We follow a proven 4-phase process to deliver your API on time and on budget.
Every project starts with a 2-week Roadmap phase where we define the API specification, endpoints, and data models. You get a fixed price and timeline before we write code.
Development runs in 2-week sprints with automated tests and continuous deployment. We audit security and compliance before the final release.
What you get when you ship a REST API with IRPR
Every delivery includes these essential assets, with no hidden surprises.
When we hand over your API, you receive everything needed to maintain and evolve it. All assets are in your repository from day one.
- Source code in your GitHub/GitLab repository
- OpenAPI 3.0 specification file
- Postman collection with example requests
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Automated test suite (unit, integration, load tests)
- Monitoring dashboard (Datadog or CloudWatch)
- Error tracking (Sentry)
- Deployment guide and runbook
- 1 year of bug fixes included
- 3 months free post-launch support
