Professional API Development CompanyAPI Development
We build custom APIs that integrate with your stack. 8-12 week delivery with fixed pricing.
IRPR is a professional API development company building REST APIs, GraphQL endpoints, WebSocket servers, and microservice gateways. We use Node.js, Python, Go, and Java with frameworks like Express, Fastify, Apollo GraphQL, and Spring Boot.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. All code is deployed to AWS or GCP with CI/CD pipelines.
Founders scaling a SaaS product hire us to build payment APIs that handle Stripe subscriptions and 10,000 requests per second. CTOs at fintech companies use us for secure tokenization APIs. Healthcare directors need FHIR-compliant APIs for patient data exchange. Ecommerce VPs rely on us for real-time inventory APIs that sync with Shopify and ERP systems.
Types of software we ship.
REST API Development
Stateless HTTP APIs with JSON responses. Built with Express or Fastify, secured with JWT and OAuth 2.0.
GraphQL API Development
Flexible query schemas with Apollo GraphQL. Reduces over-fetching and frontend development time by 40%.
WebSocket API Development
Real-time bidirectional communication for chat, live data feeds, and collaboration tools. Uses Socket.IO or ws library.
Microservices API Gateway
Single entry point for multiple microservices. Handles rate limiting, authentication, and routing with Kong or NGINX.
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio, and more. We handle authentication, rate limits, and error retry logic.
Internal API Development
APIs for internal microservices and legacy system wrappers. Uses gRPC or message queues for high throughput.
Real-Time API Development
Low-latency APIs for live dashboards, notification systems, and IoT data streams. Built on Server-Sent Events or MQTT.
Payment API Development
Tokenized, PCI-compliant payment APIs supporting Stripe, Braintree, and Adyen. Includes idempotency keys and webhook handling.
We build for every business type.

Professional API Development Company By The Numbers
Real metrics from 200+ API projects shipped across 50+ countries.
IRPR has delivered production APIs for fintech, healthcare, ecommerce, and logistics companies. Our average API project handles 5,000 requests per second with 99.9% uptime guaranteed. We use AWS, GCP, and Azure with auto-scaling and CloudFront CDN.
Every API includes end-to-end encryption, API key management, rate limiting, and structured logging (ELK stack). Our teams ship in 8-12 weeks with a fixed price — no hourly surprises. 98% of projects launch on time.
How IRPR Differs From Other API Development Companies
Most agencies bill hourly and hand off messy code. IRPR delivers clean APIs on a fixed schedule.
We start with a 2-week Roadmap phase where we define the API spec, endpoints, data models, and security requirements. You get a fixed price and timeline before any code is written. No scope creep, no change orders.
Every API ships with automated tests, API documentation (Swagger/OpenAPI), CI/CD pipelines, and runbooks. We deploy to your cloud account and transfer full ownership of all source code and infrastructure.
- Hourly billing with unknown total cost
- No API specification before coding
- Missing security review (OWASP top 10)
- No automated tests or CI/CD
- Code owned by agency
- No documentation or runbooks
- Fixed price from the Roadmap phase
- Complete API spec before development starts
- Security audit with penetration testing
- Automated tests (unit, integration, load)
- Full code ownership transferred to you
- OpenAPI docs, monitoring, and runbooks
Our API Development Process: From Roadmap to Release
We follow a four-phase process that delivers production-ready APIs in 8-12 weeks.
Phase 1 (Idea) is a 1-day discovery call where we map your business goals to technical requirements. Phase 2 (Roadmap) is a 2-week sprint that produces a detailed API spec, ERD diagrams, and a fixed-cost proposal.
Phase 3 (Product) is the main build phase — 6-10 weeks of coding, testing, and security reviews. Phase 4 (Release) includes deployment, monitoring setup (Datadog, Sentry), and a 30-day warranty.
What Ships With Every API Project
Every API includes these deliverables as standard — no extra charge.
We don't just hand over a code repository. Every API project includes production infrastructure, monitoring, documentation, and runbooks. You can hand the project to any internal team after delivery.
All code is owned by you from day one. We never license or restrict your use of the API we build. Our team is available for a 30-day handover period.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- API documentation in Swagger/OpenAPI format
- Postman collection with environment variables
- Automated unit and integration tests (Jest/Pytest)
- Load test results and capacity recommendations
- Sentry error tracking and Datadog APM setup
- Deployment to your AWS/GCP account with Terraform
- Security scan report (OWASP ZAP, dependency check)
- 30-day post-release support and runbooks
What we ship in this practice.
Payment API for a Fintech Startup

Why teams hire us.
Fixed price from day one
Every project is quoted at a fixed price in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
Senior engineers only
Our team has an average of 10+ years of experience. Every engineer has shipped at least 3 production APIs before joining IRPR. Juniors are not assigned to your project.
Full code ownership transferred
You own all source code, documentation, and infrastructure configurations. We license nothing, and you can modify or redeploy the API without any restrictions.
Compliance built in
We build HIPAA-compliant APIs with BAA agreements, PCI-DSS tokenization, SOC 2 logging, and FERPA data privacy. Security is reviewed at every sprint.
8-12 week delivery guarantee
98% of our projects ship on or before the deadline. We use 2-week sprints with clear milestones so you always know where the project stands.
Post-release support included
Every API comes with a 30-day warranty. We monitor uptime, fix bugs, and help with documentation handover. You can extend support if needed.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
