We build production-grade REST APIs that handle millions of requests per day. Fixed price, 8-12 week delivery, full ownership.
IRPR is an expert rest api development vendor that builds custom REST APIs for web, mobile, and SaaS products. We use Node.js, Python (FastAPI), Go, and Java (Spring Boot) with PostgreSQL, MongoDB, or Redis for data. Every API is documented with OpenAPI 3.0 and tested with Postman or Insomnia.
We ship a production-ready API in 8-12 weeks with fixed pricing from $80K to $250K. Our APIs handle 10,000+ requests per second, support OAuth 2.0 authentication, and meet compliance standards like HIPAA, PCI-DSS, and SOC 2. You get full source code ownership and a CI/CD pipeline with automated tests.
CTOs hire us when their in-house team lacks API expertise. Startup founders hire us to build the backend for their MVP. Enterprise architects hire us to replace legacy SOAP APIs with modern RESTful endpoints. Product managers hire us to integrate third-party services like Stripe, Salesforce, or Twilio.
Multi-tenant REST API with rate limiting and usage tracking. Built with Node.js + PostgreSQL, deployed on AWS ECS.
Push notifications, real-time sync, and offline support via REST endpoints. Uses Firebase Cloud Messaging and Redis caching.
Product catalog, cart, checkout, and order management APIs. Integrates with Stripe, Shopify, and Magento via webhooks.
HIPAA-compliant REST API handling patient records, appointments, and billing. Uses FHIR standards and AES-256 encryption.
PCI-DSS compliant REST API for payment processing, account management, and fraud detection. Uses Plaid and Stripe Connect.
Lightweight REST API for device registration, telemetry ingestion, and command execution. Uses MQTT bridge and InfluxDB time-series storage.
ETL-style REST API that transforms and syncs data between Salesforce, HubSpot, and custom databases. Uses Apache Kafka for streaming.
MLS-compliant REST API for property listings, agent profiles, and appointment scheduling. Integrates with IDX brokers and Zillow.
We have built over 200 REST APIs for companies in 50+ countries, from seed-stage startups to Fortune 500 enterprises.
Our team of senior engineers has deep experience with RESTful design principles, API versioning, and documentation. We follow the OpenAPI 3.0 specification for every endpoint, generate interactive Swagger UI docs, and include Postman collections for testing. Every API ships with automated unit tests, integration tests, and load tests using k6 or Artillery.
We use a fixed-price model with a 2-week Roadmap phase. During Roadmap, we define the API contract, choose the tech stack, and estimate the exact cost. No hourly billing. No surprise invoices. You know the price before we write a single line of code.
Most API development shops treat your project as a time-and-materials ticket. We treat it as a product.
Generic dev shops often start coding without a clear API contract. They skip documentation, use inconsistent naming conventions, and deliver endpoints that are hard to maintain. You end up with technical debt and a team that disappears after the last invoice.
IRPR builds APIs like we own them. Every endpoint follows a consistent naming pattern (nouns, plural, versioned). We write OpenAPI 3.0 docs that your frontend team can use immediately. We set up monitoring with Datadog or New Relic from day one. And we hand over the full source code with a CI/CD pipeline so your team can deploy changes in minutes.
We follow a four-phase process that turns your idea into a production-ready API in 8-12 weeks.
Phase 1 (Idea) takes 1 week. We map your business logic into data models, define user roles, and identify third-party integrations. Phase 2 (Roadmap) takes 1-2 weeks. We produce a detailed API specification, choose the tech stack, and give you a fixed price.
Phase 3 (Product) takes 6-8 weeks. Our engineers build the API in 2-week sprints. You see working endpoints every sprint and can request changes. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand over documentation and source code.
You get a production-ready API with everything needed to run in the real world.
Every API we build ships with OpenAPI 3.0 documentation, Postman collections, and a CI/CD pipeline on GitHub Actions. We include authentication (OAuth 2.0, JWT, or API keys), rate limiting, error handling, and logging. Your team can start integrating the API on day one of delivery.
We also provide a runbook that covers deployment steps, environment variables, scaling guidelines, and common troubleshooting. If you need ongoing support, we offer a monthly retainer for maintenance and feature updates. But you are never locked in - you own the code.

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 exact cost before we write code.
We hire engineers with 8+ years of experience. No juniors, no offshore teams, no training wheels. Every API is built by someone who has shipped production APIs before.
You own every line of code we write. We put it in your repository from day one. There is no license fee, no platform lock-in, no ongoing royalty. You can take the code and run it yourself.
We build APIs that meet HIPAA, PCI-DSS, SOC 2, and FERPA standards. Our engineers know how to handle PHI, PII, and financial data. We configure encryption, access controls, and audit logs by default.
Every endpoint ships with OpenAPI 3.0 docs, a Swagger UI, and a Postman collection. Your frontend team can start integrating the same day we deliver. We also provide a runbook for deployment and maintenance.
From idea to production, we manage everything: architecture, development, testing, deployment, monitoring, and documentation. You get one point of contact and a single team that knows your API inside out.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
