Experienced API Development CompanyAPI Development
We build production-grade APIs in 8-12 weeks. Fixed price, no surprises.
IRPR is an experienced API development company that builds REST, GraphQL, and SOAP APIs for startups and enterprises. We use Node.js, Go, Python, and PostgreSQL to create APIs that handle millions of requests per day.
Every API ships in 8-12 weeks with a fixed price between $80K and $250K. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA standards. Our APIs include rate limiting, authentication (OAuth 2.0, JWT), and automated testing.
CTOs hire us when their internal team lacks API security expertise. Product managers hire us to integrate with Salesforce, Stripe, or Twilio. Founders hire us to build the backend for their SaaS MVP in 10 weeks.
Types of software we ship.
REST API development
Stateless HTTP APIs with JSON responses. Built with Express.js, FastAPI, or Spring Boot. Includes Swagger documentation.
GraphQL API development
Flexible query language APIs using Apollo Server or Yoga. Reduces over-fetching and speeds up mobile app data loading.
Webhook integration
Real-time event-driven APIs that push data to Stripe, Slack, or custom endpoints. Includes retry logic and idempotency.
Microservices API gateway
Centralized gateway using Kong or AWS API Gateway. Handles routing, authentication, and rate limiting for 10+ services.
Third-party API integration
Connect your system to Salesforce, HubSpot, QuickBooks, or Shopify. Includes error handling and data transformation.
Internal API for legacy systems
Wrap legacy databases or COBOL systems with modern REST APIs. Use Docker and CI/CD for easy deployment.
Real-time API with WebSockets
Low-latency APIs for chat, live dashboards, or IoT. Built with Socket.io or AWS AppSync. Scales to 100K concurrent connections.
API security audit and hardening
Penetration testing, OWASP Top 10 checks, and implementation of OAuth 2.0, rate limiting, and encryption. Delivers a security report.
We build for every business type.
SaaS companies
Fintech and banking
Healthcare and life sciences
Ecommerce and retail
Logistics and supply chain
Why choose an experienced API development company
Building a production API requires more than just code. You need security, scalability, and compliance from day one.
IRPR has shipped 200+ APIs for companies in healthcare, fintech, and logistics. Our senior engineers average 12 years of experience. We use automated testing with Jest and Postman to catch errors before they reach production.
Every API includes rate limiting, authentication via OAuth 2.0 or API keys, and monitoring with Datadog. We deploy on AWS ECS or Kubernetes with a 99.9% uptime SLA. Our clients see 40% fewer production incidents compared to their previous vendors.
The difference between a generic dev shop and an experienced API company
Most agencies build APIs that break under load or fail security audits. IRPR builds APIs that scale from day one.
A generic dev shop might deliver a REST API in 6 weeks, but it will lack rate limiting, proper error handling, and documentation. You will spend months fixing security holes and performance bottlenecks.
IRPR delivers a production-ready API with automated tests, CI/CD pipelines, and monitoring. We include 30 days of post-launch support. Our clients report 50% fewer support tickets after launch.
- No rate limiting, API crashes under 100 req/s
- No automated tests, manual testing only
- No Swagger or OpenAPI documentation
- No CI/CD, manual deployment
- No security audit, fails PCI-DSS or HIPAA
- Hourly billing, no fixed price
- Rate limiting and throttling out of the box
- 100% test coverage with Jest and Postman

Our API development process in 4 phases
We follow a structured process that delivers a working API in 8-12 weeks.
Phase 1 defines the API contract using OpenAPI 3.0. Phase 2 builds the core endpoints with authentication. Phase 3 adds monitoring, rate limiting, and documentation. Phase 4 deploys to production with a 30-day support window.
Each phase ends with a demo and a sign-off. You see working code every 2 weeks. No black boxes, no surprises.
What ships with every API project
Every API includes these deliverables by default. No hidden costs.
You get the full source code in your private GitHub repository. We set up automated deployments via GitHub Actions to AWS ECS. Every endpoint is tested and documented.
We include a monitoring dashboard with Datadog that tracks latency, error rates, and request volume. You get alerts for any anomaly. All code is yours. No licensing fees.
