Premium REST API Development CompanyREST API
We ship production-grade REST APIs for web and mobile apps. Get a custom API designed, built, and deployed in 8-12 weeks.
IRPR builds premium REST APIs using Node.js, Express, and PostgreSQL with automated CI/CD pipelines on GitHub Actions. Each API follows OpenAPI 3.0 specs and includes Jest unit tests and Supertest integration tests.
You get a fully documented, deployed REST API in 8-12 weeks with fixed pricing starting at $80K. Every project includes Docker containerization, Prometheus monitoring, and compliance with SOC 2, HIPAA, or PCI DSS as required.
We work with startup CTOs who need a production-ready API for their SaaS MVP. Enterprise architects replacing legacy SOAP services hire us. Product managers at fintech companies require PCI-compliant payment APIs. And growth-stage founders building multi-platform products trust us.

Results that speak for themselves
Our premium REST API development delivers measurable outcomes for every client.
We have shipped 200+ REST APIs across 50 countries, with an average delivery of 12 weeks per project. Our APIs handle millions of requests per day with 99.9% uptime.
Every API comes with automated load testing reports and security scans. Clients report reducing integration time by 60% using our OpenAPI documentation and Postman collections.
The difference between generic API shops and IRPR
Most agencies deliver half-baked APIs. We deliver production-ready systems from day one.
Generic offshore developers often skip documentation, ignore CI/CD, and have no security review. Their APIs break under load and lack monitoring.
IRPR treats each API as a product. We write OpenAPI 3.0 specs, configure Sentry error tracking, and run load tests with k6 before launch.
- Unclear scope leading to scope creep
- No API documentation or outdated
- No CI/CD pipeline
- No load testing or security audits
- Single developer bottleneck
- No monitoring or alerting
- Fixed scope and timeline in week 2
- Full OpenAPI 3.0 documentation
- Automated CI/CD with GitHub Actions
- Load tested with k6, security scanned with OWASP ZAP
- Senior engineers only, no handoffs
- Prometheus + Grafana monitoring out of the box
Our 4-phase API development process
We follow a proven roadmap that turns your idea into a documented, deployed API.
Phase 1: Discovery and Architecture. We define endpoints, data models, error handling, and rate limiting. You get a technical specification document.
Phase 2: Design and Prototyping. We create OpenAPI 3.0 specs and build a minimal prototype. You test endpoints before full development begins.
What ships with every REST API project
All deliverables are included in the fixed price. No hidden extras.
Every project ships with source code in your GitHub repository, full documentation, and a Postman collection. You own everything from day one.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (YAML/JSON)
- Postman collection with example calls
- Docker Compose setup for local development
- CI/CD pipeline using GitHub Actions
- Monitoring dashboard with Grafana
- Error tracking with Sentry integration
- Load test report from k6
- Security vulnerability scan report
- API rate limiting middleware
What we ship in this practice.
Payment Gateway API for Fintech
Built a PCI-DSS compliant payment API using Node.js, Stripe Connect, and PostgreSQL. The client reduced manual reconciliation from 15 hours/week to fully automated.
Patient Data API for Telemedicine
Delivered a HIPAA-compliant FHIR API with Redis caching and AES-256 encryption. The startup integrated with 3 EHR systems and onboarded 500 doctors in 8 weeks.
Order Management API for Ecommerce
Created an order and inventory API using Elasticsearch and RabbitMQ. The brand processed 10,000 orders per hour during Black Friday with zero downtime.
MLS Aggregation API for Real Estate
Built an API that ingests data from 15 MLS providers using Go and AWS Lambda. The real estate platform reduced listing sync time from 4 hours to 3 minutes.
Notification API for Social App
Developed a real-time notification API with WebSockets and Redis Pub/Sub. The app handled 1 million notifications per day with 99.9% delivery rate.
Routing API for Logistics
Designed a route optimization API using Python and Google OR-Tools. The fleet management client cut fuel costs by 18% after deployment.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. All 200+ projects shipped on budget.
Senior engineers only
Your team consists entirely of senior engineers with 8+ years of experience. No juniors, no outsourced code. Every line is reviewed by a principal architect.
Full code ownership
You own all source code, documentation, and deployment scripts from day one. No licenses, no lock-in, no recurring fees for the code itself.
Compliance built in
We design for HIPAA, PCI DSS, and SOC 2 from the start. Our security team audits every endpoint before release. 40% of our projects involve regulated data.
Post-launch support included
Every project includes 30 days of post-launch support with 8-hour response time. We fix bugs and help with deployment issues at no extra cost.
Proven delivery in 8-12 weeks
Our process is designed for speed without cutting corners. 98% of projects are delivered on time. We maintain this record across 50+ countries.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
