Leading API Development StudioDevelopment Studio
We build custom APIs that connect your systems. 8-12 week delivery, fixed price, senior engineers only.
IRPR is a leading API development studio. We build custom REST APIs, GraphQL APIs, and gRPC services using Node.js, Python, Ruby, and Go. Every API ships with Swagger/OpenAPI documentation, automated testing, and a CI/CD pipeline.
We deliver a production-ready API in 8-12 weeks. Pricing is fixed from $80K to $250K depending on complexity. Our APIs are HIPAA compliant for healthcare, PCI-DSS compliant for fintech, and SOC 2 compliant for SaaS platforms.
CTOs hire us when their in-house team lacks bandwidth for a critical integration. Product owners hire us to build the API layer for a new SaaS product. Enterprise architects hire us to modernize legacy systems with a clean API gateway. VPs of Engineering hire us to reduce technical debt in their backend.
Types of software we ship.
REST API Development
Stateless HTTP APIs with JSON payloads. Supports OAuth2, JWT, and API key auth. Uses Express.js, FastAPI, or Django REST Framework.
GraphQL API Development
Single endpoint with flexible queries. Uses Apollo Server, Hasura, or Yoga. Built with Node.js or Python. Includes schema stitching and federation.
gRPC API Development
High-performance, typed APIs using Protocol Buffers. Uses Go or C++. Ideal for microservices and real-time streaming.
API Gateway Development
Centralized gateway with rate limiting, caching, and auth. Uses Kong, Tyk, or AWS API Gateway. Handles 10K+ requests per second.
Third-Party API Integration

Why choose a leading API development studio
Good APIs save weeks of integration time. Bad APIs waste developer hours for months.
IRPR has shipped 200+ APIs for companies across 50 countries. Our APIs average 12 weeks from kickoff to production. We use OpenAPI 3.0 specs, automated tests with 95%+ coverage, and deploy on AWS/GCP/Azure with a CI/CD pipeline.
Every API comes with a developer portal, versioning strategy, and monitoring via Datadog or New Relic. We include rate limiting, caching, and error handling by default. Our APIs handle 10K requests per minute on standard infrastructure.
IRPR vs other API development shops
Most shops write code. We ship production-grade APIs with zero tech debt.
When you hire a generic development shop, you get junior developers on hourly billing. The API works but breaks under load, lacks monitoring, and has no documentation. You pay more as they fix bugs.
IRPR gives you senior engineers with 10+ years experience. We deliver a fixed-price API with OpenAPI docs, automated load testing, deployment scripts, and a 30-day warranty. No surprises.
- Hourly billing with no cap
- Junior developers assigned
- No API documentation
- No load testing
- Downtime on deployment
- No code ownership given
- Fixed price from day 1
- Senior engineers (10+ yrs)
- OpenAPI 3.0 docs included
- Load test to 10K requests/min
- CI/CD pipeline with rollback
- Full source code ownership
Our API development process in 4 phases
We follow a repeatable process that delivers a working API in 12 weeks.
Phase 1 is discovery. We map your data model, define endpoints, and write the OpenAPI spec. Phase 2 is implementation. We build the API with automated tests. Phase 3 is hardening. We run load tests and security scans. Phase 4 is deployment and handoff.
Each phase includes a demo and sign-off. You see the API working in your staging environment from week 4 onward. No water delivery.
What ships with every API we build
Every project includes these deliverables without extra charges.
We ship everything your internal team needs to take over. Source code in your GitHub or GitLab repo. CI/CD pipeline with GitHub Actions or GitLab CI. OpenAPI documentation. Postman collections. Deployment scripts.
You also get monitoring dashboards, error tracking with Sentry, and a 30-day warranty. No hidden fees.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions
- OpenAPI 3.0 specification file
- Postman collection with all endpoints
- Automated test suite (95%+ coverage)
- Docker Compose file for local dev
- Deployment scripts for AWS/GCP/Azure
- Datadog or New Relic monitoring dashboard
- Sentry error tracking integration
- 30-day warranty with priority support

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after 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
IRPR hires engineers with 10+ years of experience. No juniors, no outsourced teams. Your project is built by a senior who has designed and deployed 20+ production APIs.
OpenAPI by default
Every API ships with an OpenAPI 3.0 specification. Your team gets auto-generated documentation, client SDKs, and a Postman collection. No guessing how to call an endpoint.
HIPAA, PCI, SOC 2 compliant
We build APIs that pass compliance audits. Healthcare APIs use encryption at rest and in transit with BAA. Fintech APIs meet PCI-DSS Level 1. SaaS APIs follow SOC 2 controls.
Full source code ownership
You own all code, specs, and deployment scripts when the project ends. No license fees, no vendor lock-in. Your team can modify, extend, or redeploy without IRPR.
30-day warranty on every API
After deployment, we fix any functional bugs for 30 days at no cost. If an endpoint returns wrong data or breaks, we patch it within 24 hours.
