The Best API Development Studio for Scalable ProductsDevelopment Studio
We build REST, GraphQL, and gRPC APIs that ship in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR is an API development studio that builds production-grade APIs using Node.js, Python, Go, and frameworks like Express, FastAPI, and Apollo. Every API ships with OpenAPI 3.0 documentation, rate limiting, and monitoring via Datadog or Sentry.
We deliver a fully functional API in 8-12 weeks with a fixed price between $80,000 and $250,000. Our APIs meet compliance requirements including HIPAA, PCI-DSS, and SOC 2 depending on your industry.
SaaS founders building API-first products hire us to avoid long hiring cycles. Enterprise teams replace legacy SOAP APIs with modern REST/GraphQL. Startups building mobile backends get a scalable foundation. Ecommerce platforms unify order and inventory data through a single gateway.
Types of software we ship.
REST API Development
Create stateless, cacheable REST APIs with Express.js or FastAPI. Includes OpenAPI specs, pagination, and HATEOAS links.
GraphQL API Development
Build flexible GraphQL APIs using Apollo Server or Yoga. Enables clients to request exactly the data they need.
gRPC API Development
High-performance gRPC APIs using Protocol Buffers. Ideal for microservices communication and low-latency systems.
WebSocket API Development
Real-time bidirectional APIs for chat, live feeds, and notifications. Implemented with Socket.IO or native WebSockets on Node.js.
Serverless API Development
Deploy APIs on AWS Lambda or Cloudflare Workers. Auto-scaling, pay-per-execution, and zero server management.
API Gateway Implementation
Centralize authentication, rate limiting, and logging with Kong or AWS API Gateway. Unify multiple backend services.
Microservices API Mesh
Design service mesh APIs using Istio or Linkerd. Manage inter-service communication, retries, and circuit breaking.
Third-Party Integration Wrapper API
Wrap multiple third-party APIs (Stripe, Salesforce, HubSpot) behind a single consistent interface. Reduces external dependency complexity.
We build for every business type.
SaaS companies
Fintech
Healthcare
Ecommerce
IoT platforms
Why IRPR is the Best API Development Studio
Our API projects ship faster, cost less, and cause fewer production issues than typical agency work.
IRPR has shipped over 200 products across 50 countries. Every API we build goes through a repeatable process: discovery, design, build, and release. We use the same tooling that top engineering teams use (GitHub Actions, Sentry, Datadog, Terraform) so your API is production-ready from day one.
Our API development studio emphasizes code quality and documentation from the start. Every endpoint is documented with OpenAPI 3.0 and includes error codes, rate limits, and authentication flows. You get a Postman collection and integration tests out of the box.
The Difference Between IRPR and a Generic Dev Shop
Most API projects fail because of vague scopes, hourly billing, and missing documentation. IRPR fixes that.
A generic dev shop often starts coding without a clear spec. You see hourly invoices mount up while the API keeps changing scope. Documentation is an afterthought, and there is no monitoring or alerting until something breaks in production.
IRPR starts with a two-week Roadmap phase where we specify every endpoint, data model, and integration point. You get a fixed price and timeline before a single line of code is written. Every API ships with Swagger/OpenAPI docs, Datadog monitoring, and a CI/CD pipeline on GitHub Actions.
- Unclear scope and endless revisions
- Hourly billing with surprise invoices
- No API documentation (or docs that rot)
- No production monitoring or alerting
- Manual deployment and no CI/CD
- You don't own the full codebase
- Fixed price agreed in week 2 after Roadmap
- All specs written before coding starts
- OpenAPI 3.0 docs generated and maintained
- Datadog monitoring and Sentry error tracking
- CI/CD pipeline with GitHub Actions and Terraform
- 100% code ownership transferred to you
Our 4-Phase API Development Process
Every project follows the same proven framework: Idea, Roadmap, Product, Release.
We don't start coding blindly. The first two weeks are dedicated to a Roadmap that defines every endpoint, data model, and integration point. After that, the build phase is fully scoped with no surprises.
The Product phase typically runs 6-8 weeks for a standard API. During Release, we deploy to production, set up monitoring, and hand over full ownership. You get a production-ready API with a 30-day warranty.
What Ships with Every API
We don't just hand over code. You get a complete production system with tooling and documentation.
Every API project includes a Postman collection, OpenAPI 3.0 spec, integration tests, and a deployment script. We set up CI/CD on GitHub Actions and monitoring on Datadog. You can deploy to a new environment with one command.
Error tracking via Sentry and structured logging with Winston or Pino are included. Rate limiting, authentication (JWT or OAuth2), and comprehensive error responses are built into the API design from the start.
- OpenAPI 3.0 specification (Swagger UI)
- Postman collection with example requests
- Unit and integration tests (Jest, pytest)
- CI/CD pipeline on GitHub Actions
- Deployment scripts for AWS, GCP, or Azure
- Sentry error tracking integration
- Datadog monitoring dashboard
- Rate limiting and JWT/OAuth2 authentication
- Structured logging (Winston or Pino)
- API documentation hosted on GitHub Pages or ReadMe
What we ship in this practice.
Subscription Billing API for a SaaS Platform
Built a REST API to handle plan upgrades, prorations, and invoices. Integrated Stripe Billing and sent webhooks for failed payments. Reduced billing errors by 90% and saved 15 hours of manual reconciliation per week. Tech stack: Node.js, Express, PostgreSQL, Stripe.

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote during the Roadmap phase (week 2). 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
We staff each project with engineers who have 8+ years of experience. No junior devs learning on your dime. Our team averages 12 years building APIs for companies like Stripe, Shopify, and Netflix.
API-first architecture
We design APIs as products, not afterthoughts. Every endpoint is versioned, documented, and tested before integration. This approach reduces frontend development time by 30% and prevents breaking changes.
Full documentation included
You get an OpenAPI 3.0 spec, Postman collection, and a hosted documentation site. Our docs include code samples in 5 languages (cURL, Python, JavaScript, Go, Ruby). No more guessing what a payload looks like.
Production monitoring built-in
Every API ships with Datadog dashboards, Sentry error tracking, and PagerDuty alerts. We set up latency alerts, error rate thresholds, and uptime checks. You see every 4xx and 5xx error before your customers do.
100% code ownership
You own all source code, documentation, and deployment scripts. No lock-in, no licensing fees, no royalties. You can take the code to any internal team or another vendor. We transfer everything via GitHub and your cloud account.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
