REST API Development ServicesDevelopment Services
We build production-grade REST APIs for web, mobile, and SaaS platforms. You get a fixed price, a 12-week timeline, and clean documentation.
IRPR builds REST APIs using Node.js, Python (FastAPI, Django), Go, Java (Spring Boot), and .NET. Every API follows OpenAPI 3.0 specs with automated testing via Postman and Jest.
We ship a complete REST API in 8-12 weeks. Pricing starts at $80K and goes up to $250K depending on endpoints, integrations, and compliance needs. All projects include CI/CD pipelines, Swagger docs, and 99.9% uptime SLAs.
CTOs hire us to replace legacy SOAP or GraphQL APIs. Product managers hire us to build the backend for a new mobile app. Startup founders hire us to create the API layer for a multi-tenant SaaS platform.
Types of software we ship.
Public REST API

Why invest in REST API development services
A well-designed REST API is the backbone of modern software architecture.
REST APIs decouple your frontend from your backend. You can build a React web app, an iOS app, and a third-party integration all from the same API. This reduces development time by 40% compared to building separate backends for each platform.
IRPR has shipped REST APIs for 200+ products. Our clients see 50% faster time-to-market when they start with a RESTful backend. We use OpenAPI 3.0 to generate client SDKs automatically, cutting integration work by weeks.
Generic dev shop vs IRPR
Not all API development is the same. Here is how we differ.
Many agencies build APIs that are hard to maintain, undocumented, and break under load. They use hourly billing and deliver in 6 months.
IRPR builds REST APIs that are documented, tested, and scalable from day one. We use fixed pricing and ship in 8-12 weeks.
- hourly billing, no price cap
- no OpenAPI spec
- no automated tests
- no CI/CD pipeline
- no rate limiting or caching
- no uptime guarantee
- fixed price from $80K
- OpenAPI 3.0 spec included
- Postman test suite
- GitHub Actions CI/CD
- Redis caching + rate limiting
- 99.9% uptime SLA
How we build your REST API
We follow a four-phase process that starts with a clear roadmap.
Every project begins with a 2-week Roadmap phase. We define endpoints, data models, authentication, and integrations. You get a fixed price and a timeline before any code is written.
After the Roadmap, we build the API in 6-10 weeks. We write automated tests, set up CI/CD, and deploy to a staging environment. You review progress every 2 weeks via a live demo.
What ships with your REST API
Every REST API project includes these deliverables by default.
You own everything. Source code, documentation, and infrastructure as code are all in your repository. No licensing fees, no vendor lock-in.
We also provide a 30-day post-launch support window. If you find a bug, we fix it within 24 hours.
- Source code in your GitHub or GitLab repo
- OpenAPI 3.0 spec (Swagger UI)
- Postman collection with 100+ tests
- CI/CD pipeline on GitHub Actions
- Docker Compose for local development
- Deployment scripts for AWS ECS or Kubernetes
- Rate limiting with Redis
- JWT or OAuth2 authentication
- Sentry error tracking
- Datadog monitoring dashboard

Why teams hire us.
Fixed price, not hourly
Every REST API project gets a fixed quote in the Roadmap phase. No hourly billing, no surprise invoices. You know the cost before we write code.
12-week delivery, not 6 months
We ship a production-grade REST API in 8-12 weeks. Our average is 12 weeks for a full-featured API with 50+ endpoints and documentation.
OpenAPI spec included
Every API ships with an OpenAPI 3.0 specification. You get auto-generated client SDKs for JavaScript, Python, and Java. No reverse-engineering needed.
HIPAA, PCI-DSS, SOC 2 compliance
We build REST APIs that pass compliance audits. Our healthcare APIs are HIPAA compliant. Our fintech APIs are PCI-DSS Level 1. Our SaaS APIs support SOC 2.
You own the code
All source code, infrastructure scripts, and documentation are yours. No licensing fees, no vendor lock-in. You can deploy anywhere.
Senior engineers only
Every project is staffed with engineers who have 8+ years of experience. No junior devs. Your API is built by people who have shipped 200+ products.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
