Premium REST API Development VendorDevelopment Vendor
We build production-grade REST APIs that scale to millions of requests. 200+ products shipped, 8-12 week delivery, fixed pricing.
IRPR is a premium REST API development vendor. We build RESTful APIs using Node.js, Python (FastAPI), Go, and .NET Core. Every API ships with OpenAPI 3.0 documentation, automated tests, and a CI/CD pipeline.
A typical REST API project takes 8-12 weeks from kickoff to production. Pricing ranges from $80K to $250K depending on endpoints, integrations, and compliance needs. We support HIPAA, PCI-DSS, SOC 2, and FERPA out of the box.
CTOs hire us when their in-house team lacks API expertise. Product managers hire us to build the backend for a new SaaS MVP. Startup founders hire us to replace a slow, unreliable third-party API with a custom one. Enterprise architects hire us to migrate legacy SOAP services to modern REST.

Why choose a premium REST API development vendor
A premium vendor delivers more than code. You get architecture, security, and long-term maintainability.
IRPR has shipped 200+ REST APIs across 50 countries. Our APIs handle 10,000+ requests per second with 99.9% uptime. We use OpenAPI 3.0 for documentation, Postman collections for testing, and Datadog for monitoring.
Every API includes automated load testing with k6, security scanning with Snyk, and a deployment pipeline on AWS ECS or Kubernetes. We write integration tests that cover every endpoint. Your team gets full ownership of the code and infrastructure.
Generic dev shop vs premium REST API development vendor
Not all API development is equal. Here is what separates a premium vendor from a generic shop.
Generic dev shops build APIs that work today but break tomorrow. They skip documentation, ignore rate limiting, and leave you with no monitoring. You end up with a black box that no one on your team can maintain.
IRPR builds APIs that your team can own from day one. We write OpenAPI specs before writing code. We set up CI/CD, error tracking with Sentry, and uptime monitoring with Datadog. Your engineers get full access to the repo and infrastructure.
- No OpenAPI documentation
- No rate limiting or throttling
- No automated tests
- No CI/CD pipeline
- No monitoring or alerting
- No security scanning
- OpenAPI 3.0 spec before code
- Rate limiting with Redis
- 100% endpoint test coverage
- GitHub Actions CI/CD
- Datadog + Sentry monitoring
- Snyk dependency scanning
Our REST API development process
We follow a 4-phase process that turns your idea into a production-ready API in 8-12 weeks.
Phase 1 is the Idea phase. We map your business logic to API endpoints, define data models, and write the OpenAPI spec. This takes 1-2 weeks and costs $5K-$10K.
Phase 2 is the Roadmap. We finalize the architecture, choose the tech stack, and give you a fixed price. Phase 3 is Product - we build the API in 6-8 weeks. Phase 4 is Release - we deploy to production and hand over the code.
What ships with every REST API project
Every project includes these deliverables. No hidden extras, no surprise fees.
When IRPR builds your REST API, you get more than just endpoints. You get a complete production system that your team can run and maintain. Here is exactly what ships.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (YAML/JSON)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Dockerized development environment
- Sentry error tracking configured
- Datadog monitoring dashboard
- Load test results from k6
- Security scan report from Snyk
- Deployment guide and runbook

Why teams hire us.
Fixed price, not hourly
Every REST API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a single line of code.
Senior engineers only
Every engineer at IRPR has 8+ years of experience building REST APIs. No junior developers, no offshore teams, no code monkeys. Your project is led by a staff engineer who has shipped 20+ production APIs.
OpenAPI-first development
We write the OpenAPI 3.0 specification before writing any code. You review and approve the spec in week 1. This eliminates misunderstandings and ensures the API matches your business logic exactly.
Full code ownership
You own 100% of the source code, documentation, and infrastructure. No proprietary frameworks, no locked-in platforms, no recurring license fees. Your team can take over maintenance on day one.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the API from day one. No bolt-on security, no afterthought audits. Our APIs pass compliance audits on the first attempt.
Production monitoring included
Every API ships with Datadog dashboards, Sentry error tracking, and PagerDuty alerts. We monitor uptime, latency, and error rates for 30 days post-launch. Your team gets a fully observable system.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
