Why IRPR is the top REST API development partner
We have shipped over 200 REST APIs for clients in 50 countries.
Every API we build follows the same process: spec-first design with OpenAPI 3.0, automated testing with 90%+ coverage, and deployment on AWS or GCP with auto-scaling. Our APIs handle millions of requests per day with 99.9% uptime.
We use a fixed-price model. After a 2-week Roadmap phase, you get a fixed quote. No hourly billing, no scope creep. Average delivery is 12 weeks from kickoff to production. We also provide 30 days of post-launch support.
Generic dev shop vs IRPR as your REST API partner
Not all development partners deliver the same quality.
Many agencies start coding without a spec. They use hourly billing and change requirements mid-project. You end up with undocumented endpoints, no tests, and a fragile API that breaks in production.
IRPR starts with a detailed OpenAPI spec in week 2. You review and approve every endpoint before we write a line of code. We deliver a documented, tested, and deployed API on a fixed budget.
- No API spec before coding
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No documentation
- No post-launch support
- OpenAPI 3.0 spec approved before coding
- Fixed price from $80K
- 90%+ test coverage with Jest
- CI/CD on GitHub Actions
- Auto-generated docs with Swagger UI
- 30 days free post-launch support
How we build your REST API in 4 phases
Our process is designed for speed and clarity.
We break every project into four phases. Each phase ends with a deliverable you can review and approve. This keeps the project on track and on budget.
You are never in the dark. We use weekly demos, a shared Slack channel, and a project management board. You see progress every week.
What ships with every REST API
You get more than just code.
Every project includes everything you need to run, maintain, and scale your API. No hidden extras, no surprise costs.
You own all the code and infrastructure. We hand over the repo, the CI/CD pipeline, and the deployment scripts.
- Source code in your private GitHub repo
- OpenAPI 3.0 spec in YAML format
- CI/CD pipeline on GitHub Actions
- Automated test suite with 90%+ coverage
- Sentry error tracking and performance monitoring
- Swagger UI documentation hosted on your domain
- Deployment scripts for AWS or GCP
- Postman collection for manual testing
- 30 days of post-launch support
- Full ownership of all intellectual property

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after 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
We hire senior engineers with 8+ years of experience. No juniors, no offshore teams. Every API is built by someone who has shipped production APIs before.
Spec-first development
We write the OpenAPI 3.0 spec before any code. You review and approve every endpoint. This eliminates rework and ensures the API matches your requirements.
Full ownership
You own all the code, documentation, and infrastructure. We hand over the GitHub repo, CI/CD pipeline, and deployment scripts. No lock-in, no recurring fees.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. We use encryption at rest and in transit, audit logging, and role-based access control. Compliance is not an afterthought.
12-week delivery guarantee
Average delivery is 12 weeks from kickoff to production. We use 2-week sprints with weekly demos. If we are late, you do not pay for the extra time.
