Premium API Development StudioAPI Development
We build production-grade APIs for your product. 200+ shipped, 50+ countries, fixed pricing.
IRPR is a premium API development studio. We build REST, GraphQL, and gRPC APIs using Node.js, Go, Python, and PostgreSQL. Every API ships with OpenAPI 3.0 docs, automated tests, and rate limiting out of the box.
We deliver a production-ready API in 8-12 weeks. Pricing is fixed after a 2-week Roadmap phase, typically $80K-$250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
Founders building a data-intensive SaaS hire us to design their API layer. CTOs at healthcare companies need us for HIPAA-compliant FHIR APIs. Product managers at fintech firms engage us for PCI-DSS compliant payment APIs. Enterprise architects hire us to migrate legacy SOAP to modern REST.
Types of software we ship.
REST API Development

GraphQL API Development
Design a single GraphQL endpoint with Apollo Server, DataLoader batching, and subscription support for real-time data.
gRPC API Development
Implement high-performance gRPC services with Protocol Buffers, bidirectional streaming, and envoy proxy for HTTP/2.
Webhook Integration Service

API Gateway and Proxy
Deploy an API gateway with Kong or AWS API Gateway for rate limiting, caching, and authentication aggregation across microservices.
Internal Microservice API
Design internal REST or gRPC APIs for service-to-service communication with circuit breakers, service discovery, and distributed tracing.
Third-Party API Wrapper
Create a unified API layer that normalizes data from 3-5 external providers (e.g., Salesforce, HubSpot, QuickBooks) into one schema.
Real-Time API with WebSockets

Why a premium API development studio matters
A poorly designed API costs you months in rework and lost customers.
Generic dev shops treat APIs as an afterthought. They skip documentation, ignore rate limiting, and ship endpoints that break under load. IRPR treats your API as the product. We write OpenAPI 3.0 specs before writing a single line of code. Every endpoint gets automated load tests with k6 (up to 10,000 req/s) and error tracking via Sentry.
We have shipped 200+ APIs for clients in 50+ countries. One fintech client saw their payment API handle 500,000 transactions in the first month with zero downtime. Another healthcare client passed HIPAA audit on the first attempt because every API endpoint logged access and encrypted PHI at rest.
The difference between a premium API studio and a generic dev shop
You get a documented, tested, compliant API on a fixed budget.
Most agencies quote hourly and deliver incomplete endpoints. They skip versioning, use no schema validation, and leave you with a Postman collection that breaks after the first change. IRPR builds APIs that last. We enforce semantic versioning, use OpenAPI 3.0 for auto-generated docs, and deploy with CI/CD on GitHub Actions.
Every API we build includes rate limiting (configurable per endpoint), JWT or OAuth2 auth, structured logging with ELK stack, and a health check endpoint. We also provide a Postman collection and a simple client SDK in JavaScript or Python so your team can start integrating immediately.

- Semantic versioning from day one
- HIPAA/PCI-DSS/SOC 2 review included
- Fixed price after 2-week Roadmap
How IRPR builds your premium API in 4 phases
From idea to production in 8-12 weeks with full documentation.
Phase 1 is the Roadmap. In 2 weeks we map every endpoint, data model, auth flow, and integration. You get a fixed price contract and a detailed spec. Phase 2 is the build. Our senior engineers write the API using Node.js, Go, or Python with PostgreSQL or MongoDB. We add automated tests and CI/CD.
Phase 3 is integration testing. We run k6 load tests, validate error handling, and pen-test auth flows. Phase 4 is release. We deploy to AWS, GCP, or Azure with monitoring via Datadog and error tracking via Sentry. You own 100% of the code from day one.
What ships with every premium API from IRPR
Everything you need to go to market and maintain your API.
We do not hand over a zip file and disappear. Every API ships with a complete developer kit. Your team can start integrating within hours of deployment. The code is fully owned by you and stored in your GitHub or GitLab repository.
We also provide a 30-day post-launch support window. During that time we fix any bugs, answer questions, and help your team with the first integration. After 30 days you can extend support via a monthly retainer.
- Source code in your private GitHub repo
- OpenAPI 3.0 spec (YAML/JSON)
- Postman collection with all endpoints
- CI/CD pipeline on GitHub Actions
- Automated unit tests (Jest, pytest, or Go test)
- k6 load test script (10K req/s target)
- Deployment to AWS, GCP, or Azure
- Datadog monitoring dashboard
- Sentry error tracking
- Client SDK in JavaScript and Python
What we ship in this practice.
Payment API for a fintech startup
Built a PCI-DSS compliant payment API using Node.js, Express, and Stripe Connect. The API handles 500,000 transactions per month with 99.99% uptime. Reduced manual reconciliation from 20 hours per week to 2 hours.
FHIR API for a telemedicine platform
Designed a HIPAA-compliant FHIR R4 API using Python, FastAPI, and PostgreSQL. Integrated with Epic and Cerner EHRs. The API processes 10,000 patient records per day with full audit logging.
Inventory API for an ecommerce brand
Built a real-time inventory API using Go, Redis, and gRPC. Connected to Shopify, Amazon, and a warehouse WMS. Reduced stockouts by 40% and cut API response time from 800ms to 50ms.
Booking API for a travel marketplace
Developed a GraphQL API using Apollo Server and MongoDB for a travel booking platform. Handles 50,000 concurrent users during peak season. Integrated with Sabre and Amadeus GDS systems.
Analytics API for a SaaS platform
Built a REST API using Node.js and ClickHouse for real-time analytics. Ingests 1 million events per day with sub-second query times. The API supports tenant isolation for multi-tenant deployments.
Compliance API for a lending platform
Created a REST API for automated KYC/AML checks using Python, Flask, and Plaid. The API integrates with 3 identity verification providers and returns results in under 2 seconds. Reduced manual review time by 80%.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing. No surprise invoices. If we need more endpoints, we tell you before we start, not after.
Senior engineers only
No junior developers. Every engineer has 8+ years of experience building APIs. Our team includes former AWS engineers and contributors to OpenAPI and GraphQL specs.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs from day one. We include audit logging, encryption, and access controls in every endpoint. No retrofitting.
Documentation that ships with code
Every API gets an OpenAPI 3.0 spec, a Postman collection, and a client SDK. Your team can start integrating the day we deploy. No waiting for docs.
Load tested before launch
We run k6 load tests at 10,000 requests per second before every release. We test for latency, error rates, and concurrency. You get a test report with percentiles.
You own everything
All source code, documentation, and configurations belong to you. We put everything in your GitHub repo. There is no proprietary framework or license fee.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
