Why IRPR is a Top API Development Company
Our numbers speak for themselves. Every API we build is production-ready and backed by real results.
IRPR has shipped over 200 APIs for clients in 50+ countries. Our average API project delivers in 10 weeks with 98% on-time record. We use a fixed price model so you know the cost from day one.
Every API includes automated testing with Jest or PyTest, CI/CD with GitHub Actions, and monitoring with Datadog. We guarantee 99.9% uptime for all production APIs.
How We Differ from Other API Development Companies
Not all API development shops work the same. Here is what sets IRPR apart.
Most agencies bill hourly and let scope creep inflate costs. They hand over code with no documentation or CI/CD. You end up with an API that breaks in production and no one to call.
IRPR delivers a fixed-price API with full documentation, automated tests, and a deployment pipeline. We own the outcome, not the hours.
- Hourly billing with no cap
- No API documentation
- No automated testing
- No CI/CD pipeline
- No uptime guarantee
- Code ownership unclear
- Fixed price from $80K
- OpenAPI 3.0 docs included
- 100% test coverage with Jest or PyTest
- GitHub Actions CI/CD pipeline
- 99.9% uptime SLA
- Full source code ownership
Our API Development Process in 4 Phases
We follow a structured process to build your API. Each phase has clear deliverables and a fixed price.
Phase 1: Idea. We map your requirements, endpoints, and data models. You get a written spec in 1 week.
Phase 2: Roadmap. We design the architecture, choose the stack (Node.js, Go, or Python), and lock the price. This takes 1 week.
What Ships with Every API Project
Every API we deliver includes these items by default. No add-ons, no extras.
We believe in full transparency. Every project includes everything your team needs to run the API in production.
- Source code in your Git repository
- OpenAPI 3.0 documentation (Swagger UI)
- CI/CD pipeline with GitHub Actions
- Automated test suite (Jest or PyTest)
- Rate limiting and authentication (JWT or OAuth 2.0)
- Docker containerization
- Datadog or Sentry monitoring
- Production deployment to AWS or GCP
- Post-launch support for 30 days
