Affordable API Development AgencyAPI Development
Flat-rate pricing from $80K. Production-ready REST and GraphQL APIs in 12 weeks.
IRPR builds affordable APIs for startups and scale-ups. We use Node.js, Python, Go, and Postgres for data, with Redis caching and Docker containerization.
Every API ships in 8-12 weeks with a fixed price starting at $80K. We include HIPAA and PCI-DSS compliance where needed, with auto-scaling on AWS.
Typical buyers are CTOs needing a new product backend, founders launching an MVP, VPs of engineering outsourcing integration work, and product managers moving off legacy systems.

Why choose an affordable API development agency?
IRPR ships APIs at a fixed price with measurable results.
You get a production-ready API with load testing, monitoring, and documentation. Our APIs handle 1000+ requests per second on standard hardware.
We have built API backends for 200+ products across 50 countries. Every API includes Sentry error tracking and CloudWatch alerts out of the box.
The real cost of cheap API development
What you get with freelance or offshore teams vs IRPR.
A freelancer might quote $5K but deliver a fragile API with no tests. Offshore shops charge hourly and drag scope over 6 months.
IRPR gives you a fixed price, a clear spec, and a shipping API in 12 weeks. We own the architecture and hand over full code.
- Hourly billing with no cap
- No documentation unless you pay extra
- Single developer, no backup
- API fails under load
- No monitoring or alerting
- You own nothing until final payment
- Fixed price from $80K
- OpenAPI spec included
- Team of senior engineers
- Load tested to 1000 req/s
- Sentry + CloudWatch monitoring
- Full code ownership from day one
How we build your API in 12 weeks
A fixed four-phase process with clear milestones.
We start with a 2-week Roadmap phase where we spec the entire API: endpoints, data model, and deployment plan. You get a fixed price and timeline.
Then we build the MVP in 8-10 weeks, followed by a Release phase with load testing, security audit, and deployment.
What ships with your API
Every delivery includes production-ready infrastructure code.
You don't just get endpoints. You get the full stack from CI/CD to alerting.
Everything is versioned, documented, and tested before handoff.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions or CircleCI
- OpenAPI 3.0 specification
- Postman collection for testing
- Load test results with k6 reports
- Sentry error tracking
- CloudWatch or DataDog monitoring dashboards
- Deployment playbook (Docker + Terraform)
- API rate limiting and token management
- Database migration scripts
