API Development CompanyDevelopment Company
We build production-ready APIs in 8-12 weeks. Fixed price, full ownership, no surprises.
IRPR is an API development company that builds custom APIs for web, mobile, and SaaS products. We use Node.js, Python, Go, and Java, with frameworks like Express, FastAPI, and Spring Boot. Our APIs are designed for scale, security, and performance.
Every API ships in 8-12 weeks with a fixed price between $80K and $250K. We handle all compliance requirements: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS. You get full ownership of the code and infrastructure.
Our clients are CTOs who need to integrate with third-party services, product managers launching a new platform, and founders building an MVP that needs a reliable backend. We also work with enterprise teams modernizing legacy systems.
Types of software we ship.
REST API Development
Stateless, resource-oriented APIs using HTTP methods. We use Express, Django REST, or Spring Boot. Ideal for CRUD apps and mobile backends.
GraphQL API Development
Single endpoint with flexible queries. We build with Apollo Server or Hasura. Reduces over-fetching and speeds up frontend development.
WebSocket API Development
Real-time, bidirectional communication. We use Socket.IO, ws, or ActionCable. Perfect for chat apps, live dashboards, and gaming backends.
Microservices API Gateway
Centralized entry point for multiple services. We implement with Kong, NGINX, or AWS API Gateway. Handles auth, rate limiting, and routing.
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, or Twilio. We handle OAuth, webhooks, and data sync. Average integration takes 2-3 weeks.
Internal API (B2B) Development
Private APIs for partner integrations and internal systems. We build with OpenAPI specs, automated docs, and API key management.
Event-Driven API (Async) Development
APIs powered by message queues like Kafka, RabbitMQ, or SQS. Used for order processing, notifications, and data pipelines.
API Security & Rate Limiting
Add authentication (JWT, OAuth2), rate limiting (Redis), and input validation. We also implement API key rotation and audit logging.
We build for every business type.
SaaS companies
Healthcare
Fintech
Ecommerce
Logistics & Manufacturing
Why choose IRPR as your API development company
We have shipped over 200 APIs for clients in 50+ countries.
Every API we build is designed for production from day one. We use automated CI/CD pipelines, containerization with Docker, and orchestration with Kubernetes. Our APIs average 99.9% uptime and handle thousands of requests per second.
We also provide comprehensive documentation using OpenAPI/Swagger, Postman collections, and integration tests. Your team can start using the API immediately after delivery.
The IRPR difference vs generic development shops
Most agencies bill by the hour and deliver late. IRPR does the opposite.
Generic shops often start coding without a clear specification. They use hourly billing, which leads to scope creep and budget overruns. Their APIs lack proper documentation, testing, and security hardening.
IRPR starts with a fixed-price Roadmap phase (week 2) that defines every endpoint, data model, and integration point. We write automated tests, generate OpenAPI docs, and deploy with CI/CD. Your API is production-ready from day one.
- Hourly billing with no cap
- No written specification before coding
- APIs often lack rate limiting and auth
- Documentation is an afterthought
- No automated testing or CI/CD
- You don't own the full codebase
- Fixed price, no surprises
- Detailed Roadmap with every endpoint defined
- JWT/OAuth2, rate limiting, input validation built-in
- OpenAPI docs and Postman collections included
- CI/CD pipeline with automated tests and deploys
- Full source code ownership from day one
Our API development process in 4 phases
From idea to production in 8-12 weeks.
Phase 1: Discovery (week 1) - We map your business logic, data sources, and integration needs. You get a system architecture diagram and a tech stack recommendation.
Phase 2: Roadmap (week 2) - We produce a detailed specification with every API endpoint, request/response format, authentication method, and third-party integration. Fixed price confirmed.
What ships with every API
You get more than just code.
Every API project includes a complete delivery package. We don't just hand over a repository; we give you everything needed to maintain, scale, and monitor your API independently.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline (GitHub Actions, GitLab CI, or CircleCI)
- Automated unit tests (coverage > 80%)
- Integration tests for every endpoint
- OpenAPI 3.0 specification (Swagger)
- Postman collection with example requests
- Dockerfile and docker-compose for local development
- Health check endpoints and Sentry error tracking
- Rate limiting and authentication (JWT or OAuth2)
- Deployment guide and runbook
What we ship in this practice.
Payment processing API for a fintech startup
Built a REST API that handles $2M in monthly transactions. Integrated with Stripe and Plaid. Reduced manual reconciliation by 15 hours per week. Tech stack: Node.js, Express, PostgreSQL, Redis.

Real-time inventory API for an ecommerce brand
Built a WebSocket API that syncs inventory across 3 warehouses and 2 Shopify stores. Eliminated overselling and reduced returns by 12%. Tech stack: Go, WebSocket, Redis, Kafka.
Multi-tenant SaaS API for a CRM platform
Designed a GraphQL API serving 500+ tenants with data isolation. Implemented role-based access control and usage metering. Tech stack: Node.js, Apollo Server, PostgreSQL, Kubernetes.
Logistics tracking API for a freight company
Created a REST API that processes 10,000+ tracking updates per day from GPS devices. Integrated with Elasticsearch for real-time search. Reduced support tickets by 40%. Tech stack: Java Spring Boot, Elasticsearch, RabbitMQ.
Learning management API for an edtech platform
Built a RESTful API for course enrollment, progress tracking, and assessment scoring. Handled 50,000 concurrent users during peak hours. Tech stack: Python, Django REST, PostgreSQL, AWS Lambda.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Production-ready from day one
We ship with CI/CD, automated tests, monitoring, and documentation. Your API is ready for production immediately. We don't hand over a prototype.
Compliance built-in, not bolted on
We have built APIs for HIPAA, PCI-DSS, SOC 2, and FERPA. Compliance is part of the architecture, not an afterthought. We use encryption, audit logs, and access controls by default.
Senior engineers only
Our team consists of engineers with 10+ years of experience. No junior developers. Every PR is reviewed by a senior architect. We ship quality code.
Full ownership of code and infrastructure
You own everything we build: source code, Docker images, infrastructure as code, and documentation. No licensing fees, no vendor lock-in. You can take it anywhere.
We work with your existing stack
We integrate with your current systems: AWS, GCP, Azure, or on-prem. We use the tools you already know: Stripe, Salesforce, HubSpot, Twilio, and more. No forced technology choices.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
