Affordable API Development VendorAPI Development
Build your API in 8-12 weeks for a fixed price. No hourly billing, no scope creep.
IRPR builds custom APIs for startups and mid-market companies. We use Node.js, Python (FastAPI), Go, and Postgres to deliver REST and GraphQL endpoints that scale. Every API ships with OpenAPI documentation and automated tests.
Your API ships in 8-12 weeks for a fixed price between $80K and $250K. We handle compliance: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS. Source code is yours from day one.
We work with CTOs who need a custom API for their product, founders launching a SaaS MVP that requires a backend, and engineering leads integrating third-party services. Each gets a dedicated senior engineer who writes production code.
Types of software we ship.
REST API
Stateless endpoints with JSON responses. Built with FastAPI or Express.js. Includes rate limiting and caching.
GraphQL API
Single endpoint that returns exactly what the client requests. Uses Apollo Server with DataLoader for batching.
Webhook API
Event-driven endpoints that push data to your system in real time. Built with AWS EventBridge or Stripe webhooks.
Payment API
Securely process transactions with Stripe, Braintree, or Adyen. PCI-DSS Level 1 compliant out of the box.
Third-Party API Wrapper
Abstract external APIs (Salesforce, HubSpot, Twilio) behind a single consistent interface. Includes retry logic and error mapping.
Internal Microservice API
Decouple your monolith into small, independent services. Each microservice has its own database and deploys independently.
Real-Time API
WebSocket or Server-Sent Events for live data. Used for chat, dashboards, and live tracking. Built with Socket.io or AWS AppSync.
Data Aggregation API
Combine data from multiple sources (databases, APIs, files) into one unified endpoint. Uses ETL pipelines and Redis caching.
We build for every business type.
SaaS and platforms
Healthcare and fintech
Ecommerce and retail
Real estate and property
Logistics and operations

Affordable API development vendor vs generic dev shop
Not all API development vendors deliver the same quality. Here is the difference.
Most generic dev shops charge by the hour. They give vague estimates and change scope mid-project. You pay for their learning curve.
IRPR gives you a fixed price after a 2-week Roadmap phase. You get a senior engineer who has built 10+ APIs before. No junior developers, no time tracking.
- Hourly billing with no cap
- Junior developers learning on your project
- No documentation unless you ask
- Scope creep without change orders
- No compliance expertise
- Code ownership unclear
- Fixed price from week 2
- Senior engineer with 5+ years experience
- OpenAPI docs included in every project
- Scope locked in Roadmap phase
- HIPAA, PCI, SOC 2 built in
- Full source code ownership
