Rest API Development StudioAPI Development
We build REST APIs that power your applications. Launch in 8-12 weeks with a fixed price.
IRPR builds custom REST APIs using Node.js, Python, and Go. We design endpoints, handle authentication, and ensure security from day one.
Every project ships with a complete API specification, Postman collection, and CI/CD pipeline. Typical timeline is 8-12 weeks with a fixed price of $50K-$150K. Compliance with HIPAA, PCI-DSS, and SOC 2 is built in.
We work with startup CTOs needing an API for their mobile app, enterprise architects integrating legacy systems, SaaS founders building API-first products, and product managers launching internal developer portals.

Why choose IRPR for REST API development?
We deliver production-ready REST APIs with a proven process and fixed pricing.
Every project starts with a 2-week Roadmap phase where we define endpoints, data models, and security requirements. This locks the scope and price before any code is written.
Our senior engineers write code that scales. We use TypeScript, PostgreSQL, Redis, and Docker. Each API ships with a full test suite and deployment dashboard.
The IRPR difference for your REST API project
Generic dev shops overpromise and underdeliver. We do the opposite.
Most agencies treat API development like a black box. They start coding without a clear spec, leading to scope creep and delays. You pay hourly and get surprises.
IRPR works differently. We define every endpoint in the Roadmap phase. You get a fixed price and a firm timeline. No hourly invoices, no guesswork.
- Hourly billing with no cost ceiling
- Vague timelines and missed deadlines
- No written API specification upfront
- Junior developers working on critical endpoints
- No automated testing or CI/CD
- You own nothing until final payment
- Fixed price locked in the Roadmap phase
- 8-12 week delivery with 98% on-time record
- OpenAPI spec delivered before coding begins
- Senior engineers only (average 10+ years)
- Full test suite and CI/CD pipeline included
- You own the code from day one
How we build your REST API
Our 4-phase process keeps your project on track and on budget.
Phase 1: Discovery - We map all endpoints, data models, and authentication needs. You get a detailed Roadmap document with a fixed price.
Phase 2: Design - We finalize the OpenAPI spec and set up the development environment with PostgreSQL and Redis. You review and approve before any code is written.
What ships with every REST API project
You get more than just code. Every deliverable is designed for long-term maintainability.
Our standard package includes everything your team needs to manage and extend the API after launch. No hidden extras.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification document
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Automated test suite (unit + integration)
- Docker Compose setup for local development
- Sentry error tracking integration
- Datadog or Grafana monitoring dashboard
- Deployment guide and runbook
- API documentation portal (Stoplight or Swagger UI)
What we ship in this practice.
Real-time stock price API
Built a WebSocket-backed API that streams stock prices with sub-50ms latency. Uses Node.js, Redis, and Polygon.io. Reduced data refresh time from 2 seconds to 200ms for a fintech startup.
Patient data exchange API
Created a HIPAA-compliant REST API for a telehealth platform to share lab results with hospitals. Built with Python, Flask, and FHIR. Integrated with Epic and Cerner. Reduced data retrieval time by 70%.
Multi-channel order management API
Developed an API that syncs orders from Shopify, Amazon, and WooCommerce into one system. Uses Node.js, PostgreSQL, and RabbitMQ. Saved a retailer 15 hours of manual data entry per week.
Subscription billing API
Built a REST API for a SaaS company to manage plans, invoices, and usage metering. Integrated with Stripe and Chargebee. Handles 500,000+ subscription events per month.
Property listing API
Created a REST API for a real estate platform to aggregate MLS data from 50+ sources. Uses Express.js, MongoDB, and Elasticsearch. Reduced listing update latency from hours to 5 minutes.
Route optimization API
Developed a RESTful service for a logistics company that computes optimal delivery routes. Uses Go, Redis, and Google Maps API. Reduced fuel costs by 18% and cut delivery times by 25%.
Why teams hire us.
Fixed price, not hourly
Every REST API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
We hire only senior engineers with 10+ years of experience. No juniors. Every developer has built at least 5 production REST APIs.
8-12 week delivery guaranteed
Our process is designed for speed. 98% of projects ship on time. We use 2-week sprints and daily standups to stay on track.
Full code ownership from day one
You own all source code, documentation, and configuration from the first commit. No IP restrictions, no licensing fees.
Built-in compliance
We build APIs that meet HIPAA, PCI-DSS, and SOC 2 requirements. Data encryption at rest and in transit, audit logs, and role-based access control are included.
Post-launch support and SLAs
We offer 30 days of free bug fixes after launch. Optional maintenance contracts with 4-hour response SLAs are available.
