REST API Development VendorDevelopment Vendor
We build REST APIs that ship in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR is a REST API development vendor that builds production-grade APIs using Node.js, Python (FastAPI), Go, and .NET Core. We design RESTful endpoints with OpenAPI 3.0 specs, JWT authentication, and PostgreSQL or MongoDB backends.
Every REST API ships with a fixed price quote after a 2-week Roadmap phase. Typical projects run 8-12 weeks and cost $80K-$250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
CTOs hire us when their in-house team lacks API bandwidth. Startup founders need a REST API for their SaaS MVP. Enterprise product managers need a vendor to build a public API for third-party integrations. Healthcare IT directors need a HIPAA-compliant REST API for patient data exchange.
Types of software we ship.
Public REST API
A developer-facing API with rate limiting, API keys, and documentation via Swagger. Used by SaaS companies to enable third-party integrations.
Internal REST API
A private API for microservices communication within your infrastructure. Uses gRPC or message queues for high throughput.
REST API for Mobile Backend
A backend API that serves iOS and Android apps with push notifications, file uploads, and real-time sync via WebSockets.
REST API for Ecommerce
An API that connects your storefront to inventory, payment gateways (Stripe, PayPal), and shipping carriers (FedEx, UPS).
REST API for Healthcare
A HIPAA-compliant API for EHR/EMR integration, patient portals, and FHIR data exchange. Uses BAA agreements and encrypted payloads.
REST API for Fintech
A PCI-DSS compliant API for payment processing, KYC verification, and transaction history. Integrates with Plaid, Stripe, and Dwolla.
REST API for IoT
An API that ingests sensor data from devices, manages device registrations, and triggers alerts. Uses MQTT and AWS IoT Core.
REST API for CRM Integration
An API that syncs data between your app and Salesforce, HubSpot, or Zoho. Handles webhooks, field mapping, and deduplication.
We build for every business type.
SaaS companies
Healthcare organizations
Fintech companies
Ecommerce brands

Why hire a REST API development vendor
Building a REST API in-house takes 6+ months and costs more than hiring a vendor with a proven process.
IRPR has shipped 200+ REST APIs for clients in 50 countries. Our senior engineers use Node.js, Python, and Go to build APIs that handle 10,000+ requests per second. Every API includes OpenAPI documentation, automated tests, and a CI/CD pipeline.
We start with a 2-week Roadmap phase where we define endpoints, data models, and authentication. You get a fixed price quote before any code is written. No hourly billing, no scope creep, no surprises.
Generic dev shop vs IRPR
Not all REST API development vendors deliver the same quality. Here is how IRPR differs from a generic dev shop.
Generic dev shops assign junior developers, use outdated frameworks, and deliver APIs without documentation or tests. You pay hourly and hope for the best.
IRPR assigns senior engineers with 10+ years of experience. We write OpenAPI 3.0 specs, unit tests with 90%+ coverage, and deploy on AWS or GCP with auto-scaling. You get a fixed price and a clear timeline.
- Junior developers with 2-3 years experience
- No API documentation or specs
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No compliance support
- Senior engineers with 10+ years experience
- OpenAPI 3.0 specs generated automatically
- Fixed price after 2-week Roadmap
- 90%+ test coverage
- CI/CD on GitHub Actions or GitLab CI
- HIPAA, PCI-DSS, SOC 2 compliance
How we build your REST API
Our process has 4 phases. Each phase has a clear deliverable and a fixed timeline.
Phase 1 is the Roadmap. We spend 2 weeks defining endpoints, data models, authentication, and deployment architecture. You get a detailed spec and a fixed price quote.
Phase 2 is the Build. Our engineers write code in 2-week sprints. You see progress in a shared GitHub repo and a staging environment. Phase 3 is the Release. We deploy to production, run load tests, and hand over source code. Phase 4 is the Support. We provide 30 days of post-launch support and a 99.9% uptime SLA.
What ships with your REST API
Every REST API project includes these deliverables by default. No hidden costs.
You own everything. Source code, documentation, and deployment scripts are in your GitHub repo from day one. We do not lock you into a proprietary platform.
Every API ships with automated tests, a CI/CD pipeline, and monitoring. You can deploy to any cloud provider or on-premise server.
- Source code in your GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline on GitHub Actions
- Unit tests with 90%+ coverage
- Integration tests for all endpoints
- Docker containers for local development
- Deployment scripts for AWS or GCP
- Sentry error tracking
- Datadog or New Relic monitoring
- 30 days of post-launch support
What we ship in this practice.
Public API for a B2B SaaS platform
Built a public REST API for a SaaS company that allows third-party developers to integrate with their platform. The API handles 5,000 requests per second and reduced integration time for new partners from 4 weeks to 2 days. Tech stack: Node.js, Express, PostgreSQL, Redis, Stripe.
HIPAA-compliant API for a telemedicine app
Built a REST API for a telemedicine startup that connects patients with doctors via video calls. The API handles patient records, appointment scheduling, and payment processing. Reduced manual data entry by 8 hours per week per clinic. Tech stack: Python FastAPI, PostgreSQL, Twilio, Stripe.
PCI-DSS compliant API for a payment gateway
Built a REST API for a fintech company that processes credit card payments. The API is PCI-DSS Level 1 compliant and handles 10,000 transactions per day. Reduced chargeback rate by 15% through fraud detection. Tech stack: Go, PostgreSQL, Stripe, Plaid.
REST API for an ecommerce marketplace
Built a REST API for an ecommerce marketplace that connects buyers and sellers. The API handles product listings, orders, payments, and shipping. Reduced order processing time from 30 minutes to 5 minutes. Tech stack: Node.js, MongoDB, Stripe, FedEx API.
Internal API for a logistics company
Built a REST API for a logistics company that manages fleet tracking, route optimization, and delivery scheduling. The API reduced fuel costs by 12% through better route planning. Tech stack: Python FastAPI, PostgreSQL, Google Maps API, Twilio.
REST API for a real estate platform
Built a REST API for a real estate platform that aggregates MLS listings, manages property tours, and handles agent commissions. The API reduced listing update time from 24 hours to 5 minutes. Tech stack: Node.js, PostgreSQL, Stripe, SendGrid.
Why teams hire us.
Fixed price, not hourly
Every REST API project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
We assign engineers with 10+ years of experience in REST API development. No junior developers, no offshore teams, no handoffs. The same engineers who build the Roadmap build the API.
Full ownership from day one
Source code, documentation, and deployment scripts are in your GitHub repo from the first sprint. You own everything. No proprietary frameworks, no lock-in, no licensing fees.
Compliance built in
We build REST APIs that meet HIPAA, PCI-DSS, and SOC 2 requirements. We use encryption, audit logging, and access controls by default. No retrofitting compliance after launch.
8-12 week delivery
Most REST APIs ship in 8-12 weeks. We use 2-week sprints with demos at the end of each sprint. You see working code every 14 days, not after 6 months.
99.9% uptime SLA
Every REST API we build comes with a 99.9% uptime SLA. We use auto-scaling, load balancing, and multi-region deployment. If the API goes down, we fix it within 4 hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
