Premium REST API Development FirmAPI Development
We build production-grade REST APIs in 8-12 weeks. Fixed pricing, full ownership, and compliance built in.
IRPR is a premium rest api development firm that builds APIs for apps that demand speed, security, and scale. We use Node.js, Express, PostgreSQL, Redis, Docker, and OpenAPI 3.0 to design endpoints that just work.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance out of the box. No hidden fees, no scope creep.
We work with CTOs scaling their backend, product managers launching new API products, startups building MVPs with a clean REST layer, and enterprises replacing legacy SOAP APIs. If you need a production-ready API on a predictable timeline, we are the partner.

Why you need a premium REST API development firm
A badly built REST API breaks your app. We build APIs that handle traffic spikes, keep data secure, and scale with you.
Most internal dev teams struggle with API design. They skip rate limiting, neglect error handling, and write no documentation. That works for a prototype. It fails when you have 10,000 users.
IRPR treats your API as a product. We define endpoints with OpenAPI before writing code. We add monitoring with Sentry and Datadog. We stress test to 10x your expected load. The result: an API that stays up and stays fast.
The difference between generic dev shops and IRPR
Not all REST API development firms deliver the same quality. Here is what sets us apart.
Many dev shops quote hourly rates, skip load testing, and hand over undocumented code. You end up with an API that breaks under pressure and costs 2x more to maintain.
IRPR works differently. We price every project upfront during the Roadmap phase. We write OpenAPI specs first. We test endpoints for performance and security. You get a production-ready API with documentation, monitoring, and a full test suite.
- Hourly billing with no cap
- No OpenAPI documentation
- No load testing
- No compliance guidance
- Code ownership unclear
- Post-launch support costs extra
- Fixed price from the Roadmap phase
- OpenAPI 3.0 spec delivered before code
- Load test to 10x expected traffic
- HIPAA, PCI, SOC 2 built in
- Full code ownership in your repo
- 24/7 monitoring and maintenance plans
Our process for building your premium REST API
We follow a four-phase process to go from idea to production in 8-12 weeks.
What ships with every API project
Every project delivers a complete production system, not just code.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- OpenAPI 3.0 documentation (Swagger UI)
- Sentry error tracking and Datadog monitoring
- Load test report with 10x target traffic
- Unit and integration tests (80%+ coverage)
- Dockerized development and production environments
- Database migrations and seed scripts
- Admin dashboard for API key management
- Post-launch support guide and runbook
What we ship in this practice.
Patient Scheduling API for a Telehealth Startup
We built a HIPAA compliant REST API that handles appointment booking, provider availability, and video call initiation. The client reduced manual scheduling time by 8 hours per week. Tech stack: Node.js, PostgreSQL, Twilio, Docker.
Payment Processing API for a Fintech Platform
Developed a PCI-DSS Level 1 API that processes 50,000 transactions per day with 99.99% uptime. Integrated with Plaid for bank account verification. Tech stack: Express, Redis, Stripe, Kafka.
Order Management API for an Ecommerce Brand
Created a REST API to connect Shopify, a custom warehouse system, and a Last-mile delivery service. Order processing time dropped from 3 minutes to 12 seconds. Tech stack: Node.js, PostgreSQL, Sidekiq, ShipStation.
Multi-Tenant SaaS API for a CRM Platform
Built a REST API with tenant isolation, rate limiting, and usage-based billing via Stripe. The client onboarded 200 new tenants in the first month. Tech stack: NestJS, PostgreSQL, Redis, AWS ECS.
Real Estate Listings API for a Property Portal
Designed a REST API that aggregates MLS data, enriches with geocoding, and serves search results in under 200ms. The client saw a 40% increase in user engagement. Tech stack: Python FastAPI, Elasticsearch, Redis, Google Maps API.
IoT Telemetry API for a Logistics Company
Built a REST API that ingests GPS and temperature data from 10,000 devices, processes alerts, and feeds a dashboard. Reduced cold chain violations by 60%. Tech stack: Node.js, Kafka, TimescaleDB, Grafana.
Why teams hire us.
Fixed price from day one
We quote a fixed price after the Roadmap phase (week 2). No hourly billing. No surprise invoices. If scope changes, we talk before billing extra.
Senior engineers only
Every developer has 8+ years of experience. No juniors. No outsourcing. You talk directly to the person writing your API.
Full code ownership
You own everything. Source code, database schemas, Docker files. We deliver to your GitHub or GitLab repo from the first commit.
Compliance built in
We have built HIPAA, PCI-DSS, and SOC 2 compliant APIs. We bake encryption, audit logs, and access controls into the architecture.
12-week delivery guarantee
98% of our projects ship on time. If we are late, you decide the remedy. We have a clear escalation process.
Post-launch support
We offer maintenance contracts with 24/7 monitoring, on-call rotation, and feature updates. Your API stays healthy after launch.
