Why affordable REST API development matters
We have shipped 200+ REST APIs that power products in 50+ countries.
A well-designed REST API reduces integration time for your partners and speeds up your own frontend teams. With IRPR, you avoid the cost of a full in-house team while getting senior engineers who deliver in 12 weeks.
Our fixed-price model means no surprises. After a 2-week Roadmap, you know exactly what you pay and when you get it. We have maintained 98% on-time delivery across all projects.
How we differ from typical API shops
Most API consulting agencies charge by the hour and deliver incomplete work.
Generic dev shops often start coding before understanding your data model. They leave you with uncommented code and no documentation. IRPR follows a structured Roadmap, design, and delivery process with fully documented APIs.
You get a detailed OpenAPI spec before any code is written. We use automated CI/CD pipelines on GitHub Actions and deploy to AWS with Terraform. Every endpoint is tested with Jest and validated with Postman collections.
- Hourly billing, no fixed price

- No Roadmap phase, immediate coding
- Unclear ownership of IP
- No compliance support
- Fixed price after 2-week Roadmap
- OpenAPI 3.0 spec included
- Automated unit+integration tests
- Structured Roadmap before any code
- Full code ownership transferred
- HIPAA/SOC 2 compliance built in
Our process for building your REST API
We follow a 4-step process that ensures your API is designed right from day one.
Every project starts with a 2-week Roadmap where we define endpoints, data models, and error handling. You get a fixed price quote and a detailed plan before we write a line of code.
During Design we produce an OpenAPI spec and sequence diagrams. Development uses paired senior engineers, and we deploy to a staging environment for your team to test. The entire process takes 12-14 weeks for most MVPs.
What you get with your REST API project
Every project ships with these deliverables included in the fixed price.
No hidden extras. All documentation, tests, and deployment scripts are part of the package. Your team can maintain the API after handover without relying on IRPR.
- Source code in your private repo (GitHub/GitLab)
- OpenAPI 3.0 specification document
- Postman collection with example requests
- GitHub Actions CI/CD pipeline
- Sentry error monitoring integration
- Unit tests with Jest (80%+ coverage)
- Integration tests with Supertest
- Deployment to AWS (ECS, RDS, ElastiCache)
- API documentation site (Redoc or Swagger UI)
- One-year warranty on code defects
What we ship in this practice.
Patient Appointment REST API
Built for a telehealth startup. The API handles booking, rescheduling, and cancellations with real-time slot availability. Reduced manual data entry by 12 hours per week. Stack: Node.js, PostgreSQL, Twilio, SendGrid.
Payment Processing API for Fintech
Designed a REST API that integrates with Stripe and Plaid to handle ACH transfers, card payments, and bank verification. Achieved 99.95% uptime in the first year. Stack: Python (FastAPI), PostgreSQL, Stripe, Plaid.
E-commerce Inventory Sync API
Connected a 5000-SKU retailer's warehouse system to Shopify and Amazon. The API syncs inventory in under 2 seconds per update, reducing over-selling incidents by 90%. Stack: Go, MongoDB, RabbitMQ.
SaaS Metrics Ingestion API
Created an API for a B2B analytics platform that ingests 10M events per day. Used batch endpoints with Redis caching to keep p99 latency under 50ms. Stack: Node.js, InfluxDB, Redis, Kubernetes.
Logistics Route Optimization API
Developed a REST API that feeds delivery addresses into a Mapbox optimization engine. Reduced average route distance by 15% for a 200-truck fleet. Stack: Python (Django), PostgreSQL, Mapbox, Celery.
Real-Time Collaboration API
Built a REST API with WebSocket fallback for a project management startup. Supports 5000 concurrent users with document locking and presence. Stack: Node.js, Socket.io, Redis, MongoDB.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the 2-week Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
12-week delivery guarantee
We ship a production-ready REST API in 8-12 weeks for most MVPs. If we are late, you pay nothing extra. Our on-time rate is 98% across 200+ products.
Full code ownership
You own the source code, documentation, and IP from day one. No licenses, no lock-in. We transfer everything to your GitHub repo upon final payment.
Compliance built in
We handle HIPAA, SOC 2, PCI-DSS, and GDPR requirements during design. All APIs include audit logging, encryption at rest, and access controls.
Senior engineers only
Our team averages 10+ years of experience. Every API is built by a senior backend engineer paired with a DevOps specialist. No junior developers.
Dedicated project manager
You get a single point of contact who handles standups, progress reports, and escalations. PMs have managed average project budgets of $150K.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
