Premium API Development AgencyAPI Development
Ship production-grade APIs that integrate with anything. Fixed price, 8-12 weeks, full ownership.
IRPR builds secure, scalable APIs for web apps, mobile backends, and third-party integrations. We use Node.js, Go, Python, and cloud-native tools like AWS API Gateway and Kong for rate limiting and authentication.
Each API project ships in 8-12 weeks with a fixed price between $80K and $250K. All code passes OWASP Top 10 security checks and includes auto-generated OpenAPI documentation.
We work with CTOs who need a PCI-compliant payment gateway, product managers launching a SaaS with a public API, and engineering leads migrating from legacy SOAP to modern RESTful services.
Types of software we ship.
REST API Development
Build RESTful APIs with OpenAPI specs, JWT auth, and PostgreSQL or MongoDB. Used for CRUD backends and mobile apps.
GraphQL API Development
Develop GraphQL APIs with Apollo Server, Prisma, and real-time subscriptions. Ideal for complex data-fetching apps.
gRPC API Development
Create high-performance gRPC microservices using Protocol Buffers and Go. Low latency for internal service-to-service calls.
Microservices API Gateway
Design API gateways with Kong or Envoy to route, throttle, and authenticate traffic across dozens of microservices.
Third-Party API Integration
Integrate with Stripe, Salesforce, HubSpot, or custom APIs. Handle OAuth 2.0 flows, webhooks, and rate limiting.
Real-Time API (WebSocket)
Build real-time APIs with WebSocket or Server-Sent Events using Socket.io or AWS AppSync. For live dashboards and chat.
Data APIs for Analytics
Create data APIs with Presto, ClickHouse, or Elasticsearch to serve aggregated metrics to BI tools and dashboards.
Event-Driven API (Async)
Implement event-driven APIs with Kafka or RabbitMQ. Publish events for decoupled services and eventual consistency.
We build for every business type.

Premium API development agency stats
We have built over 200 API-backed products for clients in 50+ countries.
Every API project starts with a Roadmap phase where we define endpoints, data models, and security requirements. In week 2, you get a fixed price and timeline.
Our APIs average 99.9% uptime because we deploy on auto-scaling Kubernetes clusters with monitoring via Datadog and PagerDuty.
Premium API development vs generic dev shops
IRPR treats your API as a product, not a side task.
Most agencies build APIs without proper documentation, rate limiting, or monitoring. They use hourly billing and scope creep eats your budget.
IRPR delivers a production-grade API with OpenAPI docs, automated tests, and a CI/CD pipeline. You get full code ownership and a fixed price.
- No API design standards
- Missing rate limiting or auth
- No OpenAPI / Swagger docs
- Hourly billing with surprises
- No monitoring or alerting
- You own nothing
- RESTful or GraphQL by design
- Built-in auth (JWT, OAuth 2.0) and rate limiting
- Auto-generated OpenAPI 3.0 docs
- Fixed price after Roadmap
- Datadog monitoring and PagerDuty alerts
- You own the full code
Our premium API development process
From idea to production in four phases.
Phase 1: Discovery. We interview your stakeholders and map integration points. You get a detailed spec with endpoint definitions.
Phase 2: Roadmap. We prototype the data model and auth flow. You approve a fixed price and 8-12 week timeline.
What ships with your premium API
Every API project includes these deliverables by default.
You get a fully documented, tested, and deployable API that meets OWASP security standards.
- Source code in your GitHub repo
- Auto-generated OpenAPI 3.0 documentation
- CI/CD pipeline (GitHub Actions or GitLab CI)
- Dockerized development and production environment
- Load testing scripts (k6 or Artillery)
- Postman or Insomnia collection for manual testing
- Sentry error monitoring and Datadog APM
- Logging with structured JSON (ELK stack)
- Security report (OWASP Top 10 scan results)
- Deployment runbook and operational guide
What we ship in this practice.
Payment Gateway API for a Fintech Startup
Built a PCI-compliant payment API using Node.js, Stripe Connect, and PostgreSQL. Handled 10,000+ transactions/month and reduced PCI scope by 60%. Reduced manual reconciliation from 5 hours/week to zero.
FHIR Integration API for Telemedicine
Developed a HIPAA-compliant HL7 FHIR API with Fast Healthcare Interoperability Resources using Python and Flask. Connected to Epic and Cerner EHRs. Cut patient data retrieval time from 4 hours to 2 seconds.
Multi-Tenant Public API for SaaS Platform
Created a GraphQL API with Apollo Server and Auth0 for a B2B SaaS. Supported 50+ tenants with isolated data. Reduced third-party integration time for customers from 6 weeks to 1 week.
Real-Time Inventory API for Ecommerce Marketplace
Built a WebSocket-based API using Node.js and Redis for a furniture marketplace. Syncs inventory across 200+ suppliers in under 2 seconds. Reduced out-of-stock orders by 35%.
Route Optimization API for Logistics Company
Implemented a REST API using Go and Google OR-Tools for dynamic route optimization. Integrated with FedEx and UPS APIs. Cut delivery costs by 18% and reduced driver idle time by 2 hours/day.
Analytics API for Media Publisher
Designed a data API with ClickHouse and GraphQL for real-time article analytics. Served 10M+ daily requests with p99 latency under 50ms. Replaced a legacy nightly batch job with live dashboards.
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. You know the cost before we write code.
Senior engineers only
Our team averages 10+ years of experience in API design and distributed systems. No junior developers. Every line of code is peer-reviewed.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our record is a REST API with 30 endpoints in 6 weeks. You are not locked into a year-long contract.
Full code ownership
You own every line of code, every Docker file, every CI/CD script. We do not use proprietary frameworks. You can take the code and run it yourself.
Compliance-ready
We build APIs that pass HIPAA, PCI-DSS, SOC 2, and GDPR audits. Our security checklist includes encryption at rest and in transit, access control, and audit logs.
Async-first, global team
Our engineers work across US, EU, and Asia time zones. You get overlap hours for calls but your project moves 24/7. No waiting for time zones to align.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
