Why IRPR is the Best REST API Development Partner
We have shipped 200+ products across 50 countries, and our API projects consistently clear audit and performance benchmarks.
Our average REST API project ships in 12 weeks with a fixed price of $80K to $250K. We use OpenAPI 3.0 for specification, Postman for automated testing, and GitHub Actions for CI/CD. Every endpoint is documented and versioned.
For regulated industries, we enforce compliance from the spec phase. Healthcare APIs follow HIPAA with BAA agreements. Fintech APIs use PCI-DSS level 1 tokenization. SaaS APIs meet SOC 2 Type II controls.
Generic Dev Shop vs. IRPR as Your REST API Partner
Not all development shops build APIs that scale and pass compliance audits.
A generic dev shop hands you a JSON file and walks away. They skip rate limiting, ignore database indexing, and leave endpoints untested. Audit season becomes a nightmare.
IRPR delivers a full API package: Postman collections, OpenAPI specs, CI/CD pipelines, and monitoring dashboards on Datadog. We stay on the project until you are live and stable.

- Datadog monitoring with uptime 99.9%
- 4-week post-launch support included
Our REST API Development Process
We follow a four-phase build that keeps your API on schedule and on budget.
Every project starts with a Roadmap phase where we define endpoints, data models, and auth flows. You get a fixed price and timeline before any code is written.
The Product phase builds the API iteratively. Each sprint includes automated testing and security reviews. The Release phase deploys to your infrastructure with full CI/CD.
What Ships with Every REST API
We do not hand over just code. You get a production-ready API package.
Every REST API project includes the same baseline: source code, infrastructure configs, and monitoring setup. You own everything from day one.
- Source code in your GitHub repo
- OpenAPI 3.0 specification file
- Postman collection with environment variables
- CI/CD pipeline with GitHub Actions
- Dockerized API with Docker Compose
- Database migration scripts for PostgreSQL
- Sentry error tracking configured
- Datadog monitoring dashboard
- Readme with setup and deployment instructions
- API documentation hosted on Swagger UI

Built for scale from day one
We design APIs to handle 10,000 requests per second using Redis caching, horizontal scaling with Kubernetes, and database indexing. Your API does not need rewriting at 1 million users.
Post-launch support included
Every project includes 4 weeks of support after launch. We monitor uptime, fix bugs, and help with your first production incidents. No extra retainer needed.
