Why IRPR is a leading API development company
We ship fast and secure APIs for any platform.
We have built over 200 APIs for clients in 50+ countries. Our APIs handle millions of requests per day with 99.9% uptime.
Every API includes automated testing, CI/CD pipelines, and full documentation. We use OpenAPI 3.0 and Postman collections.
How we differ from other API agencies
Most agencies charge by the hour and deliver incomplete code.
Generic dev shops start coding without a plan. They use vague requirements and change scope weekly.
IRPR starts with a 2-week Roadmap that defines every endpoint, data model, and integration. You get a fixed price before any code is written.
- No clear API contract
- Hourly billing with surprises
- No automated tests
- Poor documentation
- No security review
- Difficult to scale
- OpenAPI spec before coding
- Fixed price from day one
- Automated test suite with 90%+ coverage
- Complete OpenAPI docs and Postman collections
- Security audit with OWASP top 10
- Horizontal scaling with AWS/GCP
Our API development process
We follow a 4-phase approach to deliver production-ready APIs.
Phase 1: Roadmap. In two weeks we define all endpoints, data models, and integrations. You get a fixed price and timeline.
Phase 2: Build. Our senior engineers code the API using your chosen stack. We ship in 8-12 weeks.
What ships with every API
You get more than just code. Here is what we deliver.
Every project includes a complete API package. No missing pieces.
You own everything from day one.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification
- Postman collection with examples
- CI/CD pipeline (GitHub Actions or GitLab)
- Docker container and docker-compose
- Sentry error tracking
- Cloud deployment scripts (AWS, GCP, or Azure)
- Load testing results (k6 or Artillery)
- Security audit report
- Admin dashboard (if applicable)
What we ship in this practice.
Real-time order tracking API for a logistics startup
We built a WebSocket-based API that pushes order status updates to 50,000+ users in real time. The client reduced support tickets by 60% and scaled to 1M requests/day. Tech stack: Go, Redis, AWS AppSync.
HIPAA-compliant patient data API for a telemedicine platform
IRPR designed a FHIR-based API that handles patient records, appointments, and billing. The platform onboarded 200 clinics in 6 months with zero compliance issues. Tech stack: Node.js, PostgreSQL, AWS HealthLake.
Payment processing API for a fintech startup
We created a REST API that integrates with Stripe and Plaid to handle subscriptions, payouts, and bank verification. The client processed $10M in transactions in the first quarter. Tech stack: Python, FastAPI, Stripe, Plaid.
Inventory sync API for an ecommerce marketplace
Built a GraphQL API that syncs inventory across 3 warehouses and 2 sales channels. The client reduced overselling by 95% and cut sync time from 30 minutes to 2 seconds. Tech stack: Node.js, GraphQL, MongoDB, RabbitMQ.
User management API for a SaaS CRM
Developed a microservices-based API for user authentication, roles, and permissions. The client scaled from 100 to 10,000 users without downtime. Tech stack: TypeScript, NestJS, PostgreSQL, Auth0.
Property listing API for a real estate platform
IRPR built a REST API that aggregates MLS data from 50+ sources and serves property details to 100,000+ monthly visitors. The client reduced data refresh latency by 80%. Tech stack: Python, Django, PostgreSQL, Elasticsearch.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Our average project is $80K-$250K.
Senior engineers only
We hire only senior engineers with 7+ years of experience. No junior developers, no outsourcing. Our team has built APIs for companies like Stripe and Airbnb.
8-12 week delivery
From Roadmap to production in 8-12 weeks. We ship fast because we follow a proven process. 98% of our projects are delivered on time.
Full ownership
You own all source code, documentation, and deployment scripts. No licensing fees, no lock-in. We hand over everything when the project is done.
Compliance built in
We build APIs that meet HIPAA, PCI-DSS, SOC 2, and FERPA standards. Our security audits cover OWASP top 10 and include penetration testing.
Post-launch support
Every project includes 30 days of free support after launch. We help you monitor, debug, and optimize. Extended support contracts are available at $5K/month.
