Premium Custom API Development CompanyAPI Development
We build secure, scalable APIs that connect your systems. 200+ products shipped in 50+ countries with 98% on-time delivery.
IRPR is a premium custom API development company. We build RESTful APIs, GraphQL backends, gRPC services, and WebSocket endpoints for web and mobile apps. Every API is designed with OpenAPI specifications, versioned from day one, and secured with OAuth 2.0 and API keys.
Our typical project ships in 8-12 weeks with fixed pricing between $80,000 and $250,000. We handle compliance for HIPAA, PCI-DSS, and SOC 2. Each API includes automated tests, CI/CD pipelines, and monitoring dashboards in Grafana.
CTOs hire us to replace legacy integration layers. Product managers hire us to launch API-first products. Startups hire us to build their core platform APIs. Enterprise architects hire us to design microservice boundaries.
Types of software we ship.
REST API
Resource-oriented endpoints with JSON responses. Built with Express.js or FastAPI. Includes pagination, filtering, and rate limiting.
GraphQL API
Single endpoint with flexible queries. Uses Apollo Server or Hasura. Supports subscriptions for real-time data.
WebSocket API
Persistent connections for low-latency updates. Built with Socket.IO or AWS API Gateway WebSockets. Ideal for chat and live dashboards.
gRPC API
High-performance binary protocol using Protocol Buffers. Used for inter-service communication in microservices. Supports streaming.
SOAP API
XML-based enterprise APIs. Integrates with legacy systems using WSDL. Supports WS-Security for financial transactions.
OpenAPI-Driven API
Spec-first development with OpenAPI 3.0. Auto-generates SDKs, docs, and mock servers. Reduces integration time by 40%.
API Gateway
Centralized entry point for multiple microservices. Uses Kong or AWS API Gateway. Handles auth, throttling, and routing.
Event-Driven API
Async communication via message brokers like Kafka or RabbitMQ. Decouples producers and consumers. Scales to millions of events per day.
We build for every business type.
SaaS platforms
Ecommerce
Healthcare
Fintech
Media & Entertainment
Why IRPR is the premium custom API development company you need
We ship production-ready APIs in 8-12 weeks with full documentation and monitoring.
Every API we build starts with a detailed specification using OpenAPI 3.0. This spec becomes the contract between frontend and backend teams. We write integration tests against the spec before writing any backend logic.
Our APIs include rate limiting, caching, and error handling from day one. We deploy with Docker and Kubernetes, and set up monitoring with Datadog or New Relic. You get 99.9% uptime guaranteed.
How we differ from other API development companies
Generic dev shops ship broken APIs. We ship production-ready systems with compliance and monitoring built in.
Most agencies write APIs without specs, skip tests, and hand off code with no docs. You end up with a black box that breaks in production.
IRPR treats every API as a product. We write specs first, automate tests, and deliver a full DevSecOps pipeline.
- No API spec until after coding
- No automated tests
- No rate limiting or caching
- No monitoring or alerts
- No documentation
- Code ownership unclear
- OpenAPI spec written before code
- 100% automated test coverage on endpoints
- Rate limiting, caching, and pagination by default
- Grafana dashboards and PagerDuty alerts
- Auto-generated docs with Redoc
- Full source code ownership from day one
Our API development process: from spec to production
We follow a 4-phase process that eliminates surprises and delivers a working API in 8-12 weeks.
Each phase has clear deliverables and a fixed price. You know exactly what you get and when you get it.
Our process works for startups launching an API-first product and for enterprises migrating legacy systems.
What ships with every premium custom API
Every API project includes these deliverables by default. No hidden extras.
We believe in transparent delivery. Everything listed here is included in the fixed price.
You own all code and can run the API independently after launch.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification file
- Auto-generated API documentation (Redoc or Swagger UI)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker Compose and Kubernetes manifests
- Grafana dashboard with request rate, latency, error rate
- PagerDuty or Slack alert integration
- 100% integration test coverage on all endpoints
- Security audit report (OWASP top 10)
What we ship in this practice.
RESTful API for logistics tracking
Built a REST API that processes 10,000 tracking updates per minute. Reduced manual tracking time by 12 hours per week. Tech stack: Node.js, PostgreSQL, Redis, AWS API Gateway.
GraphQL API for ecommerce product catalog
Replaced a REST API with GraphQL. Reduced frontend load time by 60% and eliminated over-fetching. Tech stack: Apollo Server, MongoDB, Elasticsearch, Stripe integration.
WebSocket API for real-time chat
Built a WebSocket API supporting 50,000 concurrent connections. Achieved 200ms message delivery latency. Tech stack: Socket.IO, Redis, AWS ECS, CloudFront.
gRPC API for microservices communication
Designed a gRPC service mesh connecting 12 microservices. Reduced inter-service latency by 80% compared to REST. Tech stack: Go, Protocol Buffers, Envoy, Kubernetes.
API Gateway for multi-tenant SaaS
Created a Kong API Gateway with rate limiting and JWT auth for 200 tenants. Onboarded new tenants in 15 minutes instead of 2 days. Tech stack: Kong, PostgreSQL, Node.js, Docker.
Event-driven API for IoT data ingestion
Built an event pipeline ingesting 1 million sensor readings per day. Reduced data loss to 0.01%. Tech stack: Kafka, Python, TimescaleDB, AWS Lambda.
Why teams hire us.
Fixed pricing from day one
Every API project gets a fixed quote after the Roadmap phase (week 2). No hourly billing. No surprise invoices. You know the total cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of experience in API design and distributed systems. No junior developers. Every line of code is reviewed by a senior architect.
Full code ownership
You own all source code, documentation, and infrastructure configs from day one. No licensing fees. No vendor lock-in. You can take the API to any hosting provider.
Compliance built in
We build APIs that pass HIPAA, PCI-DSS, and SOC 2 audits. Encryption at rest and in transit. Audit logging. Role-based access control. All included in the fixed price.
8-12 week delivery
We ship a production-ready API in 8 to 12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects deliver on time.
Post-launch support
After launch we provide 30 days of warranty support. We also offer ongoing maintenance packages starting at $5,000 per month. Your API stays up to date.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
