Expert REST API Development PartnerDevelopment Partner
We build scalable REST APIs that power your product. 200+ APIs shipped for startups and enterprises.
IRPR designs and builds REST APIs using Node.js, PostgreSQL, Redis, and Docker. Every API is documented with OpenAPI 3.0 and tested with Postman.
Most APIs ship in 8-12 weeks with a fixed price of $80K-$250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance from day one.
Founders launching a SaaS MVP. CTOs integrating third-party data. Product managers building mobile backends. Enterprises migrating from legacy SOAP to REST.
Types of software we ship.
Public REST API
Developer-facing API with rate limiting, API keys, and versioning. Includes Swagger docs and SDK examples.
Internal Microservice API
Lightweight REST endpoints for internal service communication. Uses gRPC where latency matters.
Third-party Integration API
Connects your product to Stripe, Salesforce, HubSpot, or custom data sources with retry logic and webhooks.
RESTful CRUD Backend
Standard CRUD API for web and mobile apps with authentication, pagination, and filtering.
Real-time Hybrid API
REST with WebSocket fallback for live data. Uses Socket.IO for real-time dashboards and notifications.
API Gateway
Single entry point that aggregates microservices, enforces auth, and logs all traffic. Built with Kong or custom Node.js.
B2B Data Exchange API
Secure REST API for enterprise partners to pull and push data. Supports SFTP and batch JSON payloads.
Mobile Backend API
API tailored for iOS/Android with push notifications (Firebase), offline sync, and optimized JSON payloads.
We build for every business type.

Why partner with an expert REST API development team
Numbers prove our approach works.
IRPR has shipped over 200 products across 50 countries. Our APIs power applications in healthcare, fintech, and SaaS.
Our REST APIs maintain 99.9% uptime with sub-50ms response times. We monitor with Datadog and Sentry.
Generic development shops vs expert REST API partner
The difference between a working API and a production-grade one is experience.
Many shops ship APIs with undefined endpoints, no docs, and hardcoded keys. Clients end up with technical debt and security holes.
IRPR builds APIs that are versioned, documented, and monitored from day one. We use environment variables, rate limiting, and OAuth 2.0.
- No API versioning
- Missing OpenAPI specs
- No rate limiting
- Hardcoded credentials
- No monitoring
- Vague timeline estimates
- Versioned endpoints from day one
- OpenAPI 3.0 documentation
- Redis-based rate limiting
- Environment variable management
- Sentry and Datadog monitoring
- Fixed-price 8-12 week roadmap
How we build your REST API in 4 phases
We follow a proven process from idea to release.
Every project starts with a 2-week Roadmap phase. We spec endpoints, model data, and produce OpenAPI docs before writing production code.
Development is iterative with weekly demos. You see a live stub API by week 3 and a fully functional API by week 8.

Production-grade compliance
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs from day one. No afterthought security - compliance is baked into the architecture.
Complete documentation and tests
Every API ships with OpenAPI 3.0 specs, Postman collections, and automated test suites hitting 90%+ code coverage. Your team can onboard in days.
You own everything
All source code, docs, and CI/CD pipelines are yours. No licensing fees, no lock-in - you can deploy or modify without IRPR.
Warranty and support included
We provide a one-year warranty on all code defects and 30 days of free post-launch support. Production incidents get a 4-hour SLA response.
