Expert API Development StudioAPI Development
We design, build, and scale APIs for web and mobile products. 12-week delivery, fixed price, full compliance.
IRPR builds production-grade APIs using REST, GraphQL, gRPC, and WebSockets. We design every endpoint with OpenAPI 3.0 specs and enforce rate limiting, authentication, and monitoring from day one.
Every project ships with source code, automated CI/CD on GitHub Actions, and full documentation on Swagger Hub. Timeline is 12 to 14 weeks, price is fixed between $80,000 and $250,000, and all APIs are built to meet HIPAA, PCI-DSS, or SOC 2 standards if required.
We work with CTOs scaling a platform, startup founders validating an MVP with API-first architecture, enterprise teams integrating legacy systems, and product managers launching new features that depend on reliable API connections.
Types of software we ship.
REST API Development
Build RESTful APIs with OpenAPI 3.0 specs. Auto-generated docs, versioning, and rate limiting. Used in ecommerce, SaaS, and mobile backends.
GraphQL API Development
Design GraphQL APIs with Apollo or Hasura. Clients query exactly what they need. Ideal for real-time dashboards and mobile apps.
gRPC API Development
High-performance gRPC APIs using Protocol Buffers. Low latency, binary format. Used for microservices communication and streaming.
WebSocket API Development
Real-time WebSocket APIs for live notifications, chat, and collaborative editing. Powered by Socket.io or native WebSockets.
Microservices API Development
Decouple monolithic apps into microservices with REST or event-driven APIs. Docker and Kubernetes orchestration included.
API Integration & Middleware
Connect third-party services like Stripe, Salesforce, or HubSpot via custom middleware. Handles authentication, transformation, and caching.
API Gateway Development
Implement API gateways with Kong or AWS API Gateway. Centralized auth, rate limiting, and routing for multiple microservices.
API Security & Authentication
Build secure APIs with OAuth 2.0, JWT, or SAML. Includes token lookup, MFA, and audit logging. Compliant with SOC 2.
We build for every business type.
Fintech
Healthcare
Ecommerce
SaaS
Enterprise
Our API development track record
We have shipped over 200 APIs for clients across 50 countries.
Every API we build starts with a clear contract in the Roadmap phase. We define endpoints, data models, authentication, and error handling before writing a single line of code.
After delivery, we provide 30 days of free production support. Your team gets access to the source code, Postman collections, and deployment scripts. We use Sentry and Datadog for monitoring and alerting.
How IRPR compares to generic dev shops
Most dev shops treat APIs as an afterthought. We treat them as the core product.
When you hire a generalist agency, you often get inconsistent code quality, no documentation, and unclear ownership. IRPR is different: we are an expert API development studio with senior engineers only.
We follow a strict process: architecture review, security audit, automated testing, and documentation generation. Every API ships with a monitoring stack and a clear SLA.
- No upfront cost estimate
- Hourly billing with scope creep
- No dedicated API architect
- Unclear code ownership
- No API documentation by default
- No monitoring or uptime guarantees
- Fixed price from Roadmap phase
- No hourly billing, no surprises
- Senior engineers with 10+ years experience
- Full code ownership upon delivery
- OpenAPI 3.0 docs included
- Sentry + Datadog monitoring with 99.9% SLA
Our API development process in 4 phases
From idea to production API in 12 to 14 weeks.
We break every project into clear phases with deliverables. The Roadmap phase (week 2) locks scope, price, and timeline. You review every phase before we move forward.
Each phase includes code reviews, automated tests, and deployment scripts. By week 10 you have a production-ready API running on your infrastructure.
What you get when we ship your API
Every project includes these deliverables by default.
Our goal is to make your API self-serve for your own development team. That means documentation, tests, and infrastructure code are part of the deliverable.
You also get a 30-day warranty period where we fix any bugs or issues at no extra cost.
- Source code in your repo (GitHub/GitLab/Bitbucket)
- OpenAPI 3.0 specification
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Docker containers for local development
- Postman collection with sample requests
- API docs hosted on Swagger Hub or Redoc
- Load testing results with k6
- Deployment playbook with runbooks
- Admin dashboard (if applicable)
What we ship in this practice.
Payment Processing API
Built a PCI-DSS compliant payment API that reduced transaction failure rate by 15%. Tech stack: Node.js, Express, Stripe Connect, PostgreSQL. Deployed on AWS ECS with CloudWatch monitoring.
Patient Data Exchange API
Developed a HIPAA-compliant FHIR API for a hospital network. Integrated with Epic and Cerner. Enabled 30% faster data sharing between departments. Tech stack: Python, FastAPI, SQL Server, Kafka.
Real-Time Inventory API
Created a WebSocket-based inventory sync API for an ecommerce brand. Handles 10,000 concurrent connections with sub-100ms latency. Tech stack: Go, Redis Pub/Sub, WebSocket, Docker.
User Authentication & Authorization API
Built an OAuth 2.0 and JWT-based auth API for a SaaS platform. Supports SSO with Google, Microsoft, and Okta. Reduced login time by 40%. Tech stack: Kotlin, Spring Boot, PostgreSQL, Redis.
Data Aggregation API for Real Estate
Designed a REST API that aggregates MLS and third-party data into a single endpoint. Cached responses with Redis, handled 5 million requests per day. Tech stack: Node.js, Express, MongoDB, Redis.
AI Chatbot API
Developed a conversational API using GPT-4 and custom fine-tuned models. Integrated with Slack and Zendesk. Reduced customer support tickets by 25%. Tech stack: Python, FastAPI, OpenAI, PostgreSQL, Celery.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Compliance built-in
We build APIs to meet HIPAA, PCI-DSS, and SOC 2 standards from day one. No after-the-fact remediation.
Documentation automated
We generate OpenAPI 3.0 specs and deploy interactive docs to Swagger Hub automatically. Your developers can start testing endpoints immediately.
10+ years average experience
Our team averages over 10 years of backend engineering experience. Every engineer has shipped production APIs for Fortune 500 companies and YC startups.
200+ APIs shipped
We have delivered more than 200 APIs for clients in 50 countries. Each one is live, scalable, and maintained.
Full ownership
You own all source code, documentation, and deployment scripts upon delivery. No licensing fees or lock-in.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
