Leading REST API Development ConsultantsREST API
We build REST APIs that integrate with your existing systems in 8-12 weeks. Fixed pricing, senior engineers only.
IRPR is a team of senior engineers who build REST APIs for companies that need reliable, scalable integrations. We use Node.js, Python, Go, and PostgreSQL to design APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. Our APIs are built to HIPAA, PCI-DSS, and SOC 2 standards. We handle authentication, rate limiting, logging, and documentation as part of every build.
We work with CTOs at SaaS companies who need a public API for their platform. We work with product managers at fintech firms who need to integrate with Stripe and Plaid. We work with engineering leads at healthcare organizations who need FHIR-compliant APIs.
Types of software we ship.
Public REST API
A customer-facing API that lets third-party developers integrate with your platform. Includes API keys, rate limiting, and Swagger docs.
Internal REST API
An API for communication between your microservices. Built with gRPC or REST, with service discovery and circuit breakers.
REST API for Mobile Apps
A backend API that powers iOS and Android apps. Optimized for low latency and offline sync with Firebase or AWS AppSync.
REST API for Ecommerce
An API that connects your storefront to inventory, payment, and shipping systems. Integrates with Shopify, Stripe, and ShipStation.

Why Hire Leading REST API Development Consultants
A well-designed REST API reduces integration time and keeps your system reliable.
IRPR has shipped 200+ products across 50 countries. Every REST API we build includes authentication (OAuth 2.0, JWT), rate limiting, error handling, and auto-generated documentation. We use OpenAPI 3.0 as the standard.
Our APIs are designed for high availability. We deploy on AWS ECS or Kubernetes with auto-scaling and health checks. We set up monitoring with Datadog and Sentry. Average response time is under 100ms at p95.
Generic Dev Shop vs. Leading REST API Development Consultants
Not all API teams deliver the same quality. Here is the difference.
Many dev shops build APIs that work but are hard to maintain. They skip documentation, use inconsistent naming, and ignore security. You end up with a system that breaks on every update.
IRPR builds APIs that are clean, documented, and secure from day one. We follow REST best practices: resource-oriented URLs, proper HTTP verbs, consistent error responses, and versioning.
- No API design document before coding
- Inconsistent endpoint naming (some plural, some singular)
- No rate limiting or throttling
- No automated tests for endpoints
- No monitoring or alerting set up
- Documentation is an afterthought
- OpenAPI 3.0 spec created in week 1 and reviewed with you
- Consistent RESTful naming and versioning (v1, v2)
- Rate limiting with 429 responses and retry-after headers
- Unit and integration tests for every endpoint
- Datadog monitoring and Sentry error tracking from day 1
- Auto-generated Swagger docs deployed with the API
Our REST API Development Process
We follow a 4-phase process to ship your REST API on time and on budget.
Every project starts with a Roadmap phase. In 2 weeks, we define the API contract, data model, and deployment plan. You get a fixed price and timeline before we write any code.
Then we build iteratively. You see working endpoints every 2 weeks. We deploy to staging for your team to test. By week 8-12, the API is live and documented.
What Ships With Your REST API
Every REST API project includes these deliverables by default.
You get everything you need to maintain and scale your API. No hidden costs, no extra fees for documentation or deployment. All code is yours from day one.
We use GitHub for version control, GitHub Actions for CI/CD, and Docker for containerization. Your team can take over immediately after we ship.
- Source code in your GitHub repo
- OpenAPI 3.0 specification document
- CI/CD pipeline on GitHub Actions
- Docker containers for local and production deployment
- Sentry error tracking and performance monitoring
- Datadog dashboards for API metrics (latency, error rate, throughput)
- Unit tests and integration tests with 80%+ coverage
- Swagger UI documentation hosted on your domain
What we ship in this practice.
Public API for a SaaS analytics platform
Built a REST API that lets customers pull their analytics data programmatically. Reduced support tickets by 40% because customers could self-serve. Tech stack: Node.js, Express, PostgreSQL, Redis, AWS ECS.
Payment processing API for a fintech startup
Designed a PCI-DSS compliant API that handles 50,000 transactions per month. Integrated with Stripe and Plaid. Reduced payment failure rate from 5% to 1.2%. Tech stack: Go, PostgreSQL, Stripe API, Docker.
Healthcare data exchange API for a telemedicine platform
Built a HIPAA-compliant REST API that syncs patient records between the platform and 3 EHR systems. Eliminated manual data entry, saving 12 hours per week per clinician. Tech stack: Python, FastAPI, FHIR, PostgreSQL, AWS Lambda.
Inventory management API for a mid-market ecommerce brand
Created a REST API that connects Shopify, warehouse system, and shipping carrier APIs. Reduced inventory discrepancies from 8% to 0.5%. Tech stack: Node.js, Express, MongoDB, Shopify API, AWS ECS.
CRM integration API for a real estate agency
Built a REST API that syncs leads from Zillow and Redfin into their custom CRM. Increased lead response time from 4 hours to 15 minutes. Tech stack: Python, Django, PostgreSQL, Celery, Redis.
Learning management system API for an edtech company
Developed a FERPA-compliant REST API that connects the LMS to student information systems. Reduced course enrollment time from 3 days to 10 minutes. Tech stack: Ruby on Rails, PostgreSQL, Redis, Docker.
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. You know the cost before we write any code.
Senior engineers only
We do not outsource or hire juniors. Every engineer on your project has 8+ years of experience building production APIs. You work directly with the person writing the code.
8-12 week delivery
We ship a production-ready REST API in 8-12 weeks. That includes design, development, testing, deployment, and documentation. No delays, no missed deadlines.
Full code ownership
You own all source code, documentation, and infrastructure config from day one. No licensing fees, no vendor lock-in. Your team can take over immediately after we ship.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. We handle authentication, encryption, audit logging, and access controls as part of every project.
Proven track record
We have shipped 200+ products across 50 countries. Our APIs handle millions of requests per day with 99.9% uptime. We have a 98% on-time delivery rate.
