Premium API Development VendorAPI Development
We build secure, scalable APIs for 50+ countries. Fixed price, 8-12 week delivery.
IRPR is a premium API development vendor. We build REST APIs, GraphQL endpoints, and gRPC services using Node.js, Python, Go, and Postgres. Every API ships with OpenAPI specs, automated tests, and rate limiting.
We deliver in 8-12 weeks with fixed pricing between $80K and $250K. Our APIs handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance. We include monitoring, error tracking, and CI/CD pipelines in every project.
Enterprise CTOs hire us to replace legacy monolithic systems. Fintech startups need PCI-compliant payment APIs. Healthcare companies require HIPAA-compliant data exchange. SaaS platforms outsource their public API development to us.
Types of software we ship.
REST API development
Stateless HTTP APIs with OpenAPI 3.0 specs, JWT auth, and Postgres. Built for scale with Redis caching.
GraphQL API development
Single endpoint with Apollo Server, Prisma ORM, and real-time subscriptions. Reduces over-fetching by 60%.
gRPC API development
High-performance remote procedure calls using Protocol Buffers. Ideal for microservices and streaming.
Webhook API development
Event-driven webhooks with retry logic, signature verification, and delivery logs. Integrates with Stripe, Slack, and SendGrid.
Payment API integration
Custom wrappers for Stripe, Square, and Braintree. Handles idempotency, refunds, and PCI-DSS compliance.
Third-party API aggregation
Unify multiple external APIs into one consistent interface. Supports caching, fallback, and rate limit management.
API gateway development
Centralized gateway with Kong or Envoy. Handles auth, logging, throttling, and version routing.
Internal API development
Private APIs for microservice communication. Uses message queues like RabbitMQ and event streaming with Kafka.
We build for every business type.

Why Choose a Premium API Development Vendor
IRPR has shipped 200+ API products across fintech, healthcare, and SaaS.
A premium API development vendor delivers more than code. You get architecture review, security audits, and production monitoring. IRPR includes Sentry error tracking, Datadog metrics, and CloudWatch alarms in every project.
Our APIs handle 10,000 requests per second with 99.9% uptime. We use Fastify for Node.js, Gin for Go, and FastAPI for Python. Every endpoint has automated load testing with k6 before launch.
Premium vs. Commodity API Development
Not all API development vendors deliver the same quality. Here is what sets IRPR apart.
Many agencies reuse boilerplate code and skip security reviews. They deliver undocumented endpoints with no monitoring. You pay hourly and hope for the best.
IRPR writes every API from scratch with your specific requirements. We deliver OpenAPI specs, Postman collections, and integration tests. Pricing is fixed from week 2 of the project.

- No API documentation
- No rate limiting or auth
- No monitoring or alerting
- No load testing
- Code ownership unclear
- Fixed price from week 2
- OpenAPI 3.0 specs included
- JWT auth and rate limiting
- Sentry + Datadog monitoring
- k6 load testing before launch
- Full code ownership
Our API Development Process
IRPR follows a 4-phase process to deliver production-ready APIs in 8-12 weeks.
Phase 1 is the Roadmap. We define endpoints, data models, and auth flows. You get a fixed price and timeline by week 2.
Phase 2 is building the API. We code endpoints, write tests, and integrate third-party services. Phase 3 is hardening: load testing, security audits, and documentation. Phase 4 is release with CI/CD, monitoring, and handoff.
What Ships With Every API
Every API project from IRPR includes these deliverables by default.
You get more than working endpoints. Every API ships with monitoring, documentation, and deployment pipelines. No hidden fees or missing pieces.
