Top API Development ServicesAPI Development
We build production-ready APIs in 8-12 weeks. Fixed pricing, senior engineers, full ownership.
IRPR builds top API development services using Node.js, Python, Go, and Postgres. We design REST, GraphQL, and gRPC endpoints that handle 10,000+ requests per second.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance from day one. You get full source code ownership.
CTOs hire us to build API layers for their SaaS platforms. Startup founders use us to launch MVPs with integrated APIs. Enterprise teams bring us in to replace legacy SOAP services with modern REST APIs.
Types of software we ship.
REST API Development
Stateless JSON APIs with OpenAPI specs. Built with Express.js or FastAPI for high throughput.
GraphQL API Development
Single endpoint with flexible queries using Apollo Server or Hasura. Reduces over-fetching by 40%.
gRPC API Development
High-performance binary APIs using Protocol Buffers. Ideal for microservices and real-time streams.
Third-Party API Integration
Connect Stripe, Salesforce, HubSpot, Twilio, or custom endpoints. OAuth 2.0 and API key management included.
API Gateway Development
Rate limiting, authentication, and routing using Kong or AWS API Gateway. Handles 50,000 concurrent users.
Microservices API Development
Decoupled service architecture with message queues (RabbitMQ, Kafka). Each service scales independently.
Real-Time API Development
WebSocket and Server-Sent Events (SSE) APIs for live dashboards, chat, and notifications. Built with Socket.io.
API Documentation & Testing
Auto-generated docs with Swagger/OpenAPI. Postman collections and automated integration tests for every endpoint.
We build for every business type.
SaaS and startups
Healthcare
Fintech

Why Top API Development Services Matter
A well-designed API is the backbone of modern software. It connects your frontend to your business logic.
Poorly built APIs cause slow page loads, broken integrations, and security holes. IRPR builds APIs with rate limiting, input validation, and encryption by default. Every endpoint is tested against 99.9% uptime targets.
We use OpenAPI 3.0 specs to document every route. Your team gets a living document that stays in sync with the code. Postman collections ship with every project so your developers can test immediately.
Generic Dev Shops vs IRPR
Not all API development services are the same. Here is the difference between a generic shop and IRPR.
Generic shops often deliver undocumented, untested APIs that break in production. They charge by the hour and scope creep is common.
IRPR delivers a documented, tested, and deployed API in 8-12 weeks. Every project has a fixed price and a clear roadmap.
- Hourly billing with no cap
- No OpenAPI documentation
- No automated tests
- No CI/CD pipeline
- No security audit
- No post-launch support
- Fixed price from day one
- OpenAPI 3.0 docs included
- 100% test coverage on endpoints
- CI/CD with GitHub Actions
- Penetration testing report
- 2 weeks free support after launch
Our API Development Process
We follow a 4-phase process that ensures your API ships on time and on budget.
Phase 1 is the Idea phase where we clarify your requirements and map out endpoints. Phase 2 is the Roadmap where we deliver a fixed quote and timeline.
Phase 3 is Product where we build and test every endpoint. Phase 4 is Release where we deploy to production and hand over full ownership.
What Ships With Every API
Every API project from IRPR includes these deliverables by default.
- Source code in your GitHub repo
- OpenAPI 3.0 documentation
- Postman collection with examples
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Unit and integration tests (100% coverage)
- Penetration test report
- Deployment scripts for AWS/GCP/Azure
- 2 weeks free post-launch support
What we ship in this practice.
SaaS Payment API
Built a REST API for a subscription billing platform using Node.js, Express, and Stripe. Reduced payment failures by 15% with idempotency keys and retry logic. Handles 5,000 requests per minute.
Healthcare FHIR API
Developed a HIPAA-compliant FHIR API for a telemedicine startup. Uses Python FastAPI and Postgres with column-level encryption. Passed HIPAA audit with zero findings.
Ecommerce Product API
Created a GraphQL API for a multi-brand ecommerce platform using Apollo Server and Redis caching. Cut page load time from 3 seconds to 400ms. Integrates with Shopify and Magento.
Fintech KYC API
Built a gRPC API for a fintech company to verify customer identities. Uses Protocol Buffers and gRPC for high throughput. Processes 10,000 KYC checks per hour with 99.9% accuracy.
Real Estate MLS API
Designed a REST API for a real estate platform to sync MLS listings. Uses Node.js and Postgres with full-text search. Reduced data sync time from 4 hours to 15 minutes.
Logistics Tracking API
Developed a real-time WebSocket API for a logistics company to track shipments. Built with Socket.io and Redis pub/sub. Provides live location updates every 5 seconds to 500 concurrent users.
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. You know the cost before we write a line of code.
Senior engineers only
We hire senior engineers with 8+ years of experience. No junior developers, no offshore teams. Every API is built by someone who has shipped production code for 50+ clients.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects finish on time.
Full code ownership
You own every line of code we write. No license fees, no vendor lock-in. Source code is in your GitHub repo from day one.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into every API from the start. No costly retrofits. We have passed 30+ compliance audits for clients.
Post-launch support
Every project includes 2 weeks of free post-launch support. We monitor your API with Sentry and Datadog. If something breaks, we fix it within 4 hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
