API Development ServicesDevelopment Services
We build production-grade APIs for web, mobile, and SaaS products. 200+ APIs shipped in 50+ countries with 98% on-time delivery.
IRPR builds custom APIs for web apps, mobile apps, and SaaS platforms. We use Node.js, Python, Go, and .NET to create REST, GraphQL, and gRPC endpoints that handle millions of requests per day.
Every API project ships with a fixed price quote after a 2-week Roadmap phase. Typical MVPs cost $80K-$250K and deliver in 8-12 weeks. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box.
Founders hire us to build APIs for their SaaS MVP. CTOs hire us to replace legacy SOAP or monolithic backends. Product managers hire us to add API integrations with Stripe, Salesforce, or HubSpot. Enterprise architects hire us to design microservices for healthcare or fintech platforms.
Types of software we ship.
REST API Development
Stateless, resource-oriented APIs using HTTP methods. Built with Express.js, FastAPI, or Spring Boot. Includes OpenAPI 3.0 docs.
GraphQL API Development
Single endpoint with flexible queries. Built with Apollo Server, Hasura, or Yoga. Reduces over-fetching for mobile and web clients.
Microservices API Development
Decoupled services communicating via gRPC or message queues. Uses Docker, Kubernetes, and NATS for event-driven architectures.
API Integration Services
Connect your app to third-party APIs like Stripe, Twilio, Salesforce, and HubSpot. Includes OAuth 2.0 flows and webhook handling.
Real-Time API Development
WebSocket and Server-Sent Events APIs for live data. Built with Socket.io, Pusher, or AWS AppSync. Used for chat, notifications, and dashboards.
API Gateway Development
Centralized entry point for multiple backend services. Uses Kong, AWS API Gateway, or NGINX. Handles rate limiting, auth, and logging.
Internal API Development
Private APIs for internal tools and microservices. Built with gRPC or Thrift for low-latency communication between services.
Public API Development
Developer-facing APIs with documentation, SDKs, and usage tiers. Includes API keys, rate limiting, and developer portals.
We build for every business type.
Healthcare
Fintech
Ecommerce
SaaS
Logistics and Travel
Why custom API development services matter
Off-the-shelf APIs rarely fit your exact data model, business logic, or compliance needs.
A custom API gives you full control over endpoints, authentication, and performance. IRPR builds APIs that handle 10,000 requests per second with sub-50ms latency. We use Redis caching, database indexing, and connection pooling to keep response times fast.
We also design APIs for specific compliance standards. For healthcare, we enforce HIPAA audit logs and encryption at rest. For fintech, we implement PCI-DSS tokenization and SOC 2 access controls. Every API ships with automated tests and a CI/CD pipeline.
Generic dev shop vs IRPR
Most agencies treat API development as a side project. IRPR treats it as the core of your product.
Generic dev shops often build APIs without documentation, monitoring, or security reviews. They use hourly billing and change scope without notice. You end up with a fragile API that breaks in production.
IRPR builds APIs with OpenAPI specs, automated tests, and Grafana dashboards from day one. We use fixed pricing based on a detailed Roadmap. Every API ships with a deployment playbook and a 30-day warranty.
- No API documentation
- No automated tests
- Hourly billing with scope creep
- No monitoring or alerting
- No security audit
- No post-launch support
- OpenAPI 3.0 docs auto-generated
- 100% test coverage for endpoints
- Fixed price after 2-week Roadmap
- Grafana + Sentry monitoring
- OWASP top 10 security review
- 30-day warranty and 1-year support option
Our API development process
We follow a 4-phase process that turns your idea into a production-ready API.
Phase 1 is the Idea phase. We map your data model, user flows, and third-party integrations. Phase 2 is the Roadmap phase where we write a detailed spec with endpoints, auth, and pricing. You get a fixed quote.
Phase 3 is the Product phase. Our senior engineers build the API in 8-12 weeks with daily commits and weekly demos. Phase 4 is the Release phase. We deploy to AWS, GCP, or Azure, set up monitoring, and hand over full ownership.
What ships with every API
Every API project includes these deliverables by default.
You get more than just code. Every API ships with documentation, tests, monitoring, and a deployment playbook. No hidden extras.
- Source code in your GitHub or GitLab repo
- OpenAPI 3.0 specification (Swagger UI)
- Automated test suite with 90%+ coverage
- CI/CD pipeline on GitHub Actions or GitLab CI
- Dockerized deployment with docker-compose
- Grafana dashboard for request metrics and errors
- Sentry error tracking with alerting
- Postman collection for manual testing
- Deployment playbook with rollback steps
- 30-day warranty with bug fixes
What we ship in this practice.
Telemedicine API for a healthcare startup
Built a HIPAA-compliant REST API for video consultations, patient records, and prescription management. Used Node.js, PostgreSQL, and Twilio Video. Reduced patient onboarding time from 15 minutes to 3 minutes.
Payment processing API for a fintech platform
Developed a PCI-DSS compliant API for card payments, ACH transfers, and recurring billing. Used Python, FastAPI, and Stripe Connect. Processed $2M in transactions in the first month.
Product catalog API for an ecommerce brand
Created a GraphQL API for product search, inventory, and pricing. Used Apollo Server, Elasticsearch, and Redis. Reduced page load time by 60% and increased conversion rate by 15%.
Multi-tenant API for a SaaS analytics platform
Built a REST API with row-level security for 500+ tenants. Used Go, PostgreSQL, and AWS API Gateway. Handled 10,000 requests per second with 99.9% uptime.
Real-time tracking API for a logistics company
Developed a WebSocket API for live GPS tracking of 1,000+ vehicles. Used Node.js, Socket.io, and Redis. Reduced dispatch response time by 40%.
Booking engine API for a travel platform
Created a REST API for hotel and flight bookings with real-time availability. Used Python, Django, and Amadeus API. Integrated with 200+ hotel partners in 3 months.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
IRPR hires only senior engineers with 8+ years of experience. No juniors, no offshore teams. Every API is built by someone who has shipped production APIs for companies like Stripe and Twilio.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into every API from day one. We use encryption at rest, audit logs, and role-based access control. No retrofitting after launch.
Full ownership
You own the source code, the infrastructure, and the IP. No licensing fees, no vendor lock-in. We hand over everything including the CI/CD pipeline and deployment playbook.
8-12 week delivery
Most API MVPs ship in 8-12 weeks. We use agile sprints with weekly demos. You see working endpoints every Friday. No 6-month black holes.
Post-launch support
Every API comes with a 30-day warranty for bug fixes. We also offer 1-year support contracts for monitoring, updates, and scaling. You are never left alone after launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
