Premium API Development Services by the numbers
Our track record shows consistent delivery of high-quality APIs across industries.
IRPR has shipped over 200 products, many of which are API-first. Our average project timeline is 12 weeks, and we maintain a 98% on-time record.
We serve clients in 50+ countries. For premium API projects, our fixed pricing starts at $80K and goes up to $250K depending on complexity and compliance needs.
The difference between generic dev shops and premium API development
Not all API developers deliver security, scalability, and clear documentation.
Most agencies use hourly billing and junior developers. They often skip comprehensive testing and documentation, leading to costly rewrites.
IRPR works with senior engineers only. Every API includes OpenAPI specs, integration tests, load tests, and a production-ready CI/CD pipeline.
- Hourly billing with no upfront price
- Junior developers learning on your project
- No compliance expertise (HIPAA/PCI)
- Minimal documentation, if any
- No automated tests or load testing
- Delayed delivery due to scope creep
- Fixed price from Roadmap (week 2)
- Senior engineers averaging 10+ years
- HIPAA, PCI-DSS, SOC 2 built in
- Full OpenAPI specification delivered
- Integration tests + load tests running in CI
- 8-12 week MVP with clear scope
Our process for premium API development
We follow a transparent step-by-step process from idea to release.
Every premium API project starts with a 2-week Roadmap where we define endpoints, data models, and security requirements. You get a fixed price and timeline.
Then we build, test, and deploy in 6-10 week sprints. You see progress weekly via GitHub, Slack, and automated deployments.
What ships with every premium API project
We deliver more than just code. Every project includes the following artifacts.
Our delivery includes everything your team needs to run the API in production from day one.
- Source code in your private GitHub repository
- OpenAPI 3.0 specification (YAML/JSON)
- CI/CD pipeline (GitHub Actions, CircleCI)
- Dockerized local development environment
- Postman collection with example requests
- Load test scripts (k6 or Artillery)
- Sentry error tracking
- Deployment scripts for AWS/GCP
- Runbook for incident response
- One month of post-launch support
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every premium API project gets a fixed quote after the 2-week Roadmap. No hourly billing, no surprise invoices, no scope creep charges.
Senior-only engineers
Our team averages 10+ years of professional experience. We do not use junior contractors or offshore juniors on any project.
Compliance built-in
HIPAA, PCI-DSS, and SOC 2 are part of our standard process. We design APIs with encryption at rest, audit logs, and access controls from day one.
Fast timeline
You get a functional MVP in 8-12 weeks. We set clear milestones and share a working demo every Friday.
Full ownership
You own 100% of the source code, API specifications, and intellectual property. IRPR claims no rights to your product.
Asynchronous workflow
Our teams work in your timezone overlap hours (minimum 4 hours daily). No delays from different time zones, and you can reach us via Slack anytime.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
