Top Rest API Development StudioRest API
We build REST APIs that ship in 12 weeks. Fixed pricing, no hidden costs.
IRPR is a top rest api development studio. We design and build custom REST APIs using Node.js, Python (FastAPI), Go, and Java (Spring Boot). Every API is documented with OpenAPI 3.0 and secured with OAuth 2.0 or JWT.
We ship a production-ready API in 12 to 14 weeks. Pricing is fixed at $80K to $250K depending on endpoints, integrations, and compliance needs. 98% of our projects ship on time. We own the uptime.
Startups hire us to build their core API before fundraising. SaaS companies need us to migrate from legacy SOAP or GraphQL. Enterprise teams use us to build internal microservices that talk to Salesforce, Stripe, and AWS.
Types of software we ship.
REST API for mobile apps
REST endpoints for iOS and Android apps syncing data with a backend. Uses Node.js and PostgreSQL.

The top rest api development studio ships with data you can trust
IRPR tracks every API build with real numbers. No fluff.
Over 200 REST APIs shipped to clients in 50+ countries. Average time to first endpoint is 2 weeks after kickoff. 98% of projects deliver on or before the fixed deadline.
Our APIs maintain 99.9% uptime post-release. We deploy on AWS ECS or Google Cloud Run with auto-scaling. Every endpoint is monitored with Datadog and alerted in PagerDuty.
How we differ from a generic api development shop
Most agencies talk about quality. IRPR ships receipts.
Generic shops start with hourly billing and vague timelines. They discover new requirements mid-project. You pay for their learning curve.
IRPR starts with a 2-week Roadmap phase. You get a fixed price, a detailed spec, and a hard deadline. No surprises. No scope creep. No code dumps.
- Hourly billing with no cap
- Timelines stretch 4-6 months
- No OpenAPI spec upfront
- Code written by juniors
- No CI/CD pipeline
- You own nothing until paid in full
- Fixed price from week 2
- MVP ready in 12 weeks
- OpenAPI 3.0 spec included
- Senior engineers only
- CI/CD on GitHub Actions at day 1
- Full code ownership from day 1
Our 4-phase process for building a rest api
From idea to production endpoints in predictable steps.
Phase 1 (Idea) takes 1 week. We map your data model, endpoints, and authentication. Phase 2 (Roadmap) takes 1 week. You get a fixed price and a detailed technical spec.
Phase 3 (Product) is 8-12 weeks of sprint cycles. We build, test, and deploy endpoints. Phase 4 (Release) hands you the API running on your AWS account with monitoring and documentation.
Everything that ships with your rest api
You get more than just code. Every project includes these deliverables by default.
No hidden line items. No post-delivery fees for documentation or deployment. Every project ships with the same checklist.
IRPR treats your API as a product, not a project. That means documentation, monitoring, and a deployment pipeline are part of the price.
- Source code in your private GitHub or GitLab repo
- OpenAPI 3.0 specification file (JSON or YAML)
- CI/CD pipeline with GitHub Actions or GitLab CI
- Postman collection with all endpoints tested
- Deployment to AWS ECS or Google Cloud Run
- Datadog monitoring dashboard for every endpoint
- PagerDuty alert rules for 5xx errors and latency
- API keys setup via OAuth 2.0 or JWT
- 20 language-specific SDK examples (Python, JS, Go, etc.)
What we ship in this practice.
Payment processing API for a fintech startup
IRPR built a PCI-DSS compliant REST API that handles transaction authorization, refunds, and payout reconciliation. The API processed 500,000 transactions in month 1. Tech stack: Node.js, PostgreSQL, Stripe Connect, AWS ECS.
Patient data exchange API for a telehealth company
A HIPAA-compliant REST API using FHIR R4 that syncs patient records between 5 EHR systems. Reduced manual data entry by 8 hours per week per provider. Tech stack: Python FastAPI, FHIR, AWS HealthLake, Datadog.
Multi-tenant API for a B2B SaaS platform
We designed a REST API with per-tenant rate limiting, custom roles, and subscription-based billing. Scaled from 10 to 200 tenants in the first quarter. Tech stack: Go, PostgreSQL, Redis, Google Cloud Run.
Inventory and order API for an ecommerce brand
A REST API connecting Shopify, warehouse WMS, and 3PL systems. Cut inventory sync lag from 4 hours to 30 seconds. Tech stack: Node.js, Shopify REST API, RabbitMQ, AWS RDS.
Data aggregation API for a real estate platform
IRPR built a REST API that pulls MLS, Zillow, and county tax data into one endpoint. Reduced data retrieval time from 12 seconds to under 300 ms. Tech stack: Python FastAPI, Elasticsearch, Redis, AWS Lambda.
Internal microservices API for a logistics company
A REST API that exposes tracking, routing, and driver management endpoints to internal dashboards. Handles 1 million requests per day with 99.9% uptime. Tech stack: Java Spring Boot, Kafka, PostgreSQL, AWS ECS.
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. You know the cost before code starts.
Senior engineers only
IRPR does not hire juniors. Every engineer has 7+ years of experience building REST APIs. You talk directly to the person writing your endpoints.
OpenAPI 3.0 by default
Every API ships with a machine-readable OpenAPI 3.0 spec. Your team can generate SDKs, test automation, and documentation from day one.
12-week MVP guarantee
We ship your first production-ready REST API in 12 weeks. If we miss the deadline, you pay nothing for the next 2 weeks. It has never happened.
Full code ownership from day 1
All code goes into your private repository from the first commit. You own every line. No licensing fees, no vendor lock-in.
Post-release monitoring and support
After launch, we monitor your API with Datadog and PagerDuty. We respond to alerts within 15 minutes during business hours. 99.9% uptime SLA.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
