Premium API Development PartnerAPI Partner
We build production-grade APIs that scale to millions of requests. Fixed price, 8-12 week delivery, full code ownership.
IRPR is a premium API development partner for companies that need APIs built right the first time. We use Node.js, Go, Python, and TypeScript with frameworks like Express, Fastify, Apollo, and tRPC to design REST, GraphQL, and gRPC APIs.
Every engagement ships a fully documented, tested, and deployed API in 8-12 weeks. Pricing is fixed from the Roadmap phase starting at $80K for a single API service and up to $250K for a multi-service architecture. We deliver under HIPAA, PCI-DSS, and SOC 2 compliance.
We work with CTOs who need to launch a product on a tight deadline, VP of Engineering who want to offload API design to experts, and founders who need a scalable backend without hiring a full team. These buyers value speed, quality, and fixed costs.

Why You Need a Premium API Development Partner
A poorly designed API costs you time, money, and developer trust.
APIs are the backbone of modern software. If your API has inconsistent endpoints, poor error handling, or no documentation, your internal teams and external partners will struggle. IRPR has shipped over 200 API-based products across 50 countries, and we have seen these problems first-hand.
A premium API development partner like IRPR ensures your API is designed with clear contracts, versioning strategy, and automated testing from day one. We use tools like Postman, Newman, and Pact for contract testing. Our APIs average 99.9% uptime on AWS and GCP.
The Difference Between a Generic Shop and a Premium API Partner
Not all API development teams are equal. Here is what sets IRPR apart.
Generic development shops often treat APIs as an afterthought. They skip documentation, use inconsistent naming, and deliver endpoints that break under load. This leads to costly rewrites and delayed launches.
IRPR treats API design as a first-class discipline. Every project starts with a Roadmap phase where we define the API contract, choose the protocol (REST, GraphQL, or gRPC), and set up CI/CD pipelines. We use OpenAPI 3.0, Apollo Studio, and Sentry for monitoring.
- No API contract before coding
- Inconsistent endpoint naming
- No automated tests for APIs
- No rate limiting or throttling
- No API documentation
- No monitoring or alerting
- OpenAPI 3.0 contract defined in week 1
- Consistent RESTful or GraphQL conventions
- Unit + integration + contract tests with Newman
- Rate limiting with token bucket algorithm
- Auto-generated interactive docs with Swagger
- Sentry + Datadog monitoring from day 1
Our 4-Phase API Development Process
We follow a repeatable process that eliminates guesswork and delivers a production-ready API in 8-12 weeks.
Every API project at IRPR goes through four distinct phases. This structure ensures no scope creep, no missed requirements, and a clear timeline from start to finish.
Each phase ends with a deliverable that you review and approve. You always know where we are and what comes next.
What Ships With Every API Project
Every API we build includes these deliverables by default. No hidden costs, no missing pieces.
When you hire IRPR as your premium API development partner, you get more than just code. We ship a complete, production-ready API system that your team can own and extend immediately.
All deliverables are reviewed by a senior engineer and tested before handoff.
- OpenAPI 3.0 or GraphQL schema documentation
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Unit tests with Jest or Mocha (90%+ coverage)
- Integration tests with Newman or Supertest
- Load test script with k6 or Artillery
- Postman collection for manual testing
- Sentry error tracking and Datadog monitoring dashboard
- Deployment to your cloud (AWS, GCP, or Azure)
- One hour of post-release support per week for 4 weeks

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Every IRPR engineer has 10+ years of experience. We do not outsource to junior devs or offshore teams. Your API is built by a senior engineer who has shipped 20+ production APIs.
Production-ready from day 1
We ship with CI/CD, monitoring, error tracking, and load testing built in. Your API goes to production with Sentry and Datadog running from the first deployment.
Full code ownership
You own every line of code we write. No licensing fees, no vendor lock-in, no proprietary frameworks. The source code goes into your GitHub repo immediately.
8-12 week delivery
We deliver a working, tested, deployed API in 8-12 weeks. This timeline is fixed in the Roadmap phase. We have shipped over 200 products on this schedule.
Compliance-ready APIs
We build APIs that pass HIPAA, PCI-DSS, and SOC 2 audits. We handle encryption, access control, and audit logging by default. No extra cost for compliance.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
