Affordable Custom API Development StudioAPI Development
We build custom APIs for your business. Fixed pricing from $80K, delivered in 8-12 weeks.
IRPR builds custom APIs using Node.js, Python, Go, and cloud-native services like AWS Lambda, API Gateway, and Kubernetes. We design REST, GraphQL, and gRPC endpoints that scale to millions of requests per day.
We ship production-ready APIs with OpenAPI documentation, CI/CD pipelines on GitHub Actions, Sentry error tracking, and Datadog monitoring. Timeline is 8-12 weeks with fixed pricing from $80K to $250K. Compliance includes HIPAA, PCI-DSS, and SOC 2.
Who hires us: SaaS founders who need an API-first product to launch quickly, healthcare companies requiring HIPAA-compliant patient data APIs, fintech startups needing PCI-DSS certified payment APIs, and ecommerce brands integrating third-party systems like Shopify or Salesforce.
Types of software we ship.
REST API
Stateless, resource-based APIs using JSON. Built with Express.js or FastAPI. Ideal for CRUD operations and public endpoints.
GraphQL API
Query language for flexible data fetching. Uses Apollo Server or Yoga. Reduces over-fetching by 40% on average.
gRPC API
High-performance RPC framework using Protocol Buffers. Built with Go or Node.js. 5x faster than REST for internal services.
WebSocket API
Real-time bidirectional communication. Built with Socket.IO or AWS API Gateway WebSockets. Used for chat, live updates, streaming.
SOAP API
XML-based protocol for enterprise systems. Supports WS-Security and XSD validation. Common in banking and government.
API Gateway
Centralized entry point for microservices. Uses Kong or AWS API Gateway. Handles rate limiting, auth, and routing.
API Integration
Connect third-party APIs like Stripe, Salesforce, or Twilio. We build middleware with Node.js or Python. Average integration takes 2-3 weeks.
API Management Platform
Full lifecycle management with developer portal, analytics, and monetization. Built on Kong or Apigee. Includes API key management and usage tracking.
We build for every business type.

Why IRPR for affordable custom API development
We deliver production-ready APIs with fixed pricing and predictable timelines.
Every API project at IRPR starts with a Roadmap phase (week 2) where we define endpoints, data models, and compliance requirements. You get a fixed quote before any code is written. No hourly billing, no scope creep.
Our team of senior engineers has shipped over 200 products across 50 countries. We use proven frameworks like Express.js, FastAPI, and Go Fiber. Each API includes automated testing, CI/CD, and monitoring out of the box.
The difference between IRPR and generic dev shops
Most agencies bill hourly and deliver late. We do the opposite.
Generic dev shops often start coding without a clear plan. They underbid, then add change orders. You end up paying 2x the estimate and waiting months for a half-baked API.
IRPR uses a fixed-price model with a detailed Roadmap. Every endpoint, every integration, every compliance requirement is scoped upfront. We deliver on time because we have done it 200 times before.
- Hourly billing with no cap
- Junior or mid-level developers
- No documentation or tests
- Scope creep without change orders
- No compliance knowledge
- Code ownership unclear
- Fixed price from $80K
- Senior engineers only (10+ years)
- OpenAPI docs + automated tests
- Scope frozen in Roadmap phase
- HIPAA, PCI-DSS, SOC 2 built in
- Full code ownership transferred
How we build your custom API in 8-12 weeks
Our four-phase process ensures your API ships on time and on budget.
We start with a 2-week Roadmap phase where we define every endpoint, data model, and integration. You approve the plan before any development begins.
Then we build, test, and deploy in 6-8 weeks. Each sprint ends with a working demo. The final week is for load testing, documentation, and handover.
What ships with every affordable custom API
Every API project includes these deliverables by default.
You get more than just code. We ship a complete production system with monitoring, documentation, and ownership.
No hidden fees, no missing pieces. Everything listed here is included in the fixed price.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests
- Sentry error tracking
- Datadog monitoring dashboards
- Rate limiting and auth (JWT or API keys)
- Deployment scripts for AWS/GCP/Azure
- Postman collection for testing
- 30-day post-launch support
What we ship in this practice.
Payment processing API for a fintech startup
Built a PCI-DSS compliant payment API using Node.js, Stripe Connect, and AWS Lambda. Processed $2M in transactions in the first month. Reduced manual reconciliation by 20 hours/week.
Patient data API for a telemedicine platform

Product catalog API for an ecommerce brand
Created a GraphQL API using Apollo Server and MongoDB. Served 10,000 products with sub-100ms response times. Integrated with Shopify and Stripe for order sync.
Real-time chat API for a SaaS collaboration tool
Built a WebSocket API using Socket.IO and Redis. Supported 10,000 concurrent connections with <50ms latency. Reduced message delivery time from 2 seconds to 200ms.
Booking API for a travel marketplace
Developed a REST API with Go and PostgreSQL. Integrated with 15 hotel booking aggregators. Handled 1 million API calls per day with 99.9% uptime. Reduced booking errors by 80%.
Property data API for a real estate platform
Built a gRPC API with Go and Elasticsearch. Served 500,000 property listings with real-time MLS data. Reduced data sync time from 4 hours to 15 minutes.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of experience. Every developer has built production APIs for companies like Stripe, Uber, and Salesforce. No juniors, no offshore outsourcing.
8-12 week delivery
We ship working APIs in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects finish on time.
Full code ownership
You own all the source code from day one. No licensing fees, no vendor lock-in. We transfer everything to your GitHub repo at the end of each sprint.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliance into the API architecture from the start. No expensive retrofits. We have delivered compliant APIs for healthcare and fintech since 2016.
Post-launch support included
Every project includes 30 days of post-launch support. We monitor uptime, fix bugs, and help with scaling. After that, we offer maintenance retainer at $4K/month.
