Leading API Development Firm for Scalable SolutionsAPI Development
We build secure REST and GraphQL APIs. You get production-ready endpoints in 12 weeks or less.
IRPR architects custom APIs for web and mobile backends. We use Node.js, Python, Go, and Next.js to build RESTful and GraphQL APIs that handle millions of requests per day.
Every API ships in 8-12 weeks with fixed pricing starting at $80K. Our APIs pass HIPAA, PCI-DSS, and SOC 2 compliance standards before launch.
Startup CTOs hire us to replace outdated monoliths. Enterprise architects engage us for microservices design. SaaS founders commission us to build API-first products. Platform teams bring us in to unify third-party integrations.
Types of software we ship.
REST API Development
Build stateless RESTful endpoints with JSON payloads. We use Express.js, FastAPI, or Spring Boot depending on your stack.
GraphQL API Development
Implement a single endpoint that returns exactly the data clients need. Apollo Server with TypeScript is our standard.
Microservices API Gateway
Design a gateway that routes, throttles, and authenticates across multiple services. Kong or AWS API Gateway with custom plugins.
Internal API Development
Connect your internal tools and databases with private APIs. We use gRPC for high-throughput inter-service communication.
Third-Party API Integration
Integrate with Stripe, Salesforce, HubSpot, and 100+ other providers. We handle rate limiting, retries, and idempotency.
API Wrapper Development
Create a unified SDK that abstracts multiple external APIs. We ship npm, PyPI, and Ruby gem packages.
Real-time API (WebSocket)
Build bidirectional real-time connections using WebSockets or SSE. Socket.IO with Redis pub/sub for horizontal scaling.
API Security & Auth
Add OAuth 2.0, JWT, and API key management to any existing API. We implement Auth0 or Firebase Auth with custom roles.
We build for every business type.
E-commerce
Fintech
Healthcare
SaaS
Logistics and Travel
Why a Leading API Development Firm Delivers
Our API engineering process ships production-ready endpoints in weeks, not months.
200+ products shipped across 50+ countries. Our APIs handle 99.9% uptime with automated monitoring and alerting via Datadog and PagerDuty.
Average API project delivers in 12 weeks at a fixed price starting $80K. We include full documentation (OpenAPI/Swagger), automated tests with >90% coverage, and deployment scripts.
How IRPR Differs from Generic API Shops
Most API development companies start coding before defining the contract.
Generic shops write vague proposals and bill by the hour. They skip API documentation and leave you with a black box you can't maintain.
IRPR starts with the Roadmap phase - a fixed-price contract that defines every endpoint, data model, and integration. You get full source code, OpenAPI docs, and CI/CD pipelines.
- Hourly billing with no cap
- No written API contract
- Ships without documentation
- Code owned by agency
- No automated tests
- No deployment scripts
- Fixed price with scope clarity
- Detailed API spec before code
- OpenAPI/Swagger docs shipped
- Full source code in your repo
- 90%+ test coverage
- CI/CD on GitHub Actions
Our API Development Process in 4 Phases
Each phase has a fixed price and a measurable deliverable.
We designed this process over 15 years of building APIs for startups and enterprises. Every project follows the same four-phase loop.
What Ships with Every API Project
Everything your team needs to own and operate the API.
Every deliverable is designed to be autonomous - your team can edit endpoints, add middleware, and redeploy without IRPR.
- Source code in your GitHub/GitLab repo
- OpenAPI 3.0 specification (JSON/YAML)
- CI/CD pipeline using GitHub Actions
- Automated test suite (Jest/Pytest) with >90% coverage
- Dockerized application with docker-compose
- Environment configuration for dev/staging/prod
- Sentry error tracking and performance monitoring
- Deployment scripts for AWS, GCP, or Azure
- Postman collection with example requests
What we ship in this practice.
Subscription Billing API for Fintech Startup
Built a RESTful billing API with Stripe integration and usage-based pricing. The API handles 500k requests per day and reduced billing errors by 95%. Tech stack: Node.js, PostgreSQL, Stripe, Redis.
Real-time Ride Tracking API for Logistics
Developed a WebSocket-based tracking API for a fleet of 1,000+ vehicles. Drivers and dispatchers saw latency drop to under 200ms. Stack: Go, WebSockets, Redis, AWS IoT.
EHR Integration API for Telehealth Platform
Created a FHIR-compliant API that connects the app to Epic and Cerner systems. Patient data sync cut from 4 hours to 2 minutes. Stack: Python/FastAPI, FHIR, PostgreSQL, Auth0.
Multi-tenant API for SaaS CRM
Designed a GraphQL API with row-level security for a CRM with 5,000+ tenants. Query times improved 40% under load. Stack: GraphQL, Apollo, TypeORM, Aurora RDS.
Payment Gateway Wrapper for E-commerce
Built a unified payment API wrapping Stripe, PayPal, and Square. Checkout conversion increased 12% after integration. Stack: Node.js, Express, Redis, Segment.
ML Model Serving API for Media Recommendation
Developed a gRPC API that serves a recommendation model to 2 million users daily. Response time stayed under 50ms at peak. Stack: Python/TensorFlow, gRPC, Kubernetes, S3.
Why teams hire us.
Fixed-Price API Contracts
Every API project starts with a Roadmap phase (week 2) where we define exact endpoints and data models. The price locks after that - no hourly billing, no scope creep.
Senior Engineers, No Juniors
Our team averages 12 years of experience building APIs for high-traffic applications. You never pay for a junior to learn on your project.
Full Code Ownership
All source code, configurations, and documentation go directly into your repositories. You own everything from day one - no IP transfer headaches.
Security Built In
We ship APIs with OAuth 2.0, JWT, rate limiting, and input validation. Every endpoint passes automated security scans (SonarQube, OWASP ZAP) before deployment.
98% On-Time Delivery
Across 200+ projects, we deliver on schedule 98% of the time. Our four-phase process with weekly demos keeps you in control of timelines.
Post-Launch Support
After deployment, we provide 30 days of warranty to fix any issues. We also offer optional retainer contracts for ongoing maintenance and new endpoints.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
