Premium API Development DevelopersAPI Development
We build secure, scalable APIs for your product. Fixed price, delivered in 8-12 weeks.
IRPR builds premium APIs for startups and enterprises. We use Node.js, Python, Go, and Rust to create REST and GraphQL endpoints that handle millions of requests per day.
Every project ships with a fixed price quote in the Roadmap phase (week 2). Typical budgets range from $80K to $250K. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA standards.
We work with CTOs who need a secure integration layer, product managers launching a SaaS platform, and founders building a data-heavy mobile app. They all need an API that works from day one.
Types of software we ship.
REST API development
Build JSON-based APIs with Express.js or FastAPI. Includes versioning, pagination, and rate limiting.
GraphQL API development
Use Apollo Server or Yoga to build flexible query layers. Supports real-time subscriptions and schema stitching.
Webhook API development
Create event-driven webhooks with retry logic, signing secrets, and delivery logs using Stripe Connect patterns.
Microservices API development
Deploy containerized APIs with Docker and Kubernetes. Each service has its own database and CI/CD pipeline.
Third-party API integration
Connect your product to Salesforce, HubSpot, Stripe, Twilio, or any public API. Includes error handling and rate limit management.
API security audit
Review authentication (OAuth 2.0, JWT), input validation, SQL injection prevention, and rate limiting. Delivers a written report with fixes.
API documentation portal
Generate interactive docs with Swagger/OpenAPI or Redoc. Includes code samples in 5 languages and a test console.
Real-time API development
Build WebSocket or Server-Sent Events endpoints for live dashboards, chat, and notifications. Uses Socket.IO or Pusher.
We build for every business type.
SaaS platforms
eCommerce
healthcare

Why premium API development developers matter
A poorly designed API breaks your product. We build APIs that scale from day one.
IRPR has shipped over 200 products across 50 countries. Every API we build starts with a Roadmap phase where we define endpoints, data models, and error handling. This phase costs $8K and takes 2 weeks. You get a fixed quote for the full build after that.
Our APIs handle 10,000+ requests per second in production. We use Redis caching, database indexing, and async workers to keep response times under 100ms. We also enforce rate limiting and input validation to prevent abuse.
Generic dev shops vs premium API development developers
Most agencies ship APIs that break under load. IRPR builds APIs that last.
Generic shops deliver endpoints without documentation, rate limiting, or monitoring. You get a single JSON file and a handshake. When traffic spikes, the API goes down.
IRPR ships with Swagger docs, Postman collections, Sentry error tracking, and Datadog monitoring. Every endpoint has a unit test and an integration test. We also set up CI/CD pipelines on GitHub Actions so you can deploy in one click.

- Hourly billing with scope creep
- Swagger/OpenAPI docs included
- Rate limiting and throttling built in
- Sentry and Datadog monitoring
- 100% unit test coverage
- GitHub Actions CI/CD pipeline
- Fixed price, no surprises
How we build your premium API
Our process is designed for speed and quality. From idea to production in 8-12 weeks.
We start with a 2-week Roadmap phase where we define every endpoint, data model, error code, and authentication method. You get a detailed spec and a fixed price quote. No guesswork.
Then we build the API in 2-week sprints. You see a working endpoint every 14 days. We deploy to staging for your QA team to test. After you approve, we go live.
What ships with your premium API
Every API project includes a complete delivery package. No hidden extras.
You own the code from day one. We put everything in your GitHub repo: source code, tests, CI/CD pipelines, and deployment scripts. You can take over development at any time.
We also include a 30-day support window after launch. If something breaks, we fix it within 4 hours. After that, we offer ongoing maintenance at $5K/month.
- Source code in your GitHub repo
- Swagger/OpenAPI documentation
- Postman collection for testing
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Unit tests (100% coverage)
- Integration tests for critical flows
- Rate limiting and input validation
- Deployment scripts for AWS/GCP/Azure
What we ship in this practice.
Multi-tenant SaaS API
Built a tenant-aware API for a B2B SaaS platform. Each tenant gets isolated data and custom rate limits. Reduced time to integrate new customers from 4 weeks to 2 days. Tech stack: Node.js, PostgreSQL, Redis, Stripe.
HIPAA-compliant patient data API
Designed a FHIR-compliant API for a telehealth startup. Handles 50,000 patient records with end-to-end encryption and audit logging. Passed HIPAA audit on first attempt. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS.
Payment processing API for fintech
Built a PCI-DSS compliant API that processes $2M in monthly transactions. Includes idempotency keys, webhook retries, and fraud scoring. Reduced chargebacks by 40%. Tech stack: Go, PostgreSQL, Stripe Connect, Redis.
Real-time inventory API for eCommerce
Created a WebSocket API that syncs inventory across 500 stores in real time. Eliminated overselling and reduced manual stock checks by 20 hours/week. Tech stack: Node.js, Socket.IO, MongoDB, RabbitMQ.
MLS data API for real estate platform
Integrated with 12 MLS feeds and normalized the data into a single REST API. Supports 200+ property fields and geospatial queries. Tech stack: Python, FastAPI, PostgreSQL, Elasticsearch.
Learning management API for edtech
Built a FERPA-compliant API for a university LMS. Handles 100,000 student records with role-based access and gradebook endpoints. Tech stack: Ruby on Rails, PostgreSQL, Redis, Sidekiq.
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 we write a single line of code.
8-12 week delivery
We ship a production-ready API in 8-12 weeks. Our average is 12 weeks across 200+ projects. We use 2-week sprints so you see progress every 14 days.
Senior engineers only
Every developer has 10+ years of experience. No juniors, no offshore teams. Your API is built by someone who has shipped 20+ production APIs before.
Full code ownership
You own everything in your GitHub repo from day one. Source code, tests, CI/CD pipelines, deployment scripts. No lock-in, no license fees.
Compliance built in
We build APIs that pass HIPAA, PCI-DSS, SOC 2, and FERPA audits. We use encryption at rest and in transit, audit logs, and role-based access controls.
Post-launch support included
Every project includes 30 days of support after launch. We fix bugs within 4 hours. After that, ongoing maintenance is $5K/month for monitoring, updates, and patches.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
