API Development VendorDevelopment Vendor
Senior engineers build your APIs in 8-12 weeks for a fixed price. You get a production-ready API with docs, monitoring, and a CI/CD pipeline.
IRPR builds custom APIs using Node.js, Python (FastAPI), and Go. We handle data storage with PostgreSQL, Redis, and Kafka. Each API includes rate limiting, authentication (JWT/OAuth 2.0), and auto-generated documentation (OpenAPI/Swagger).
We ship a production-grade API in 8-12 weeks for a fixed price between $80,000 and $250,000. Compliance standards like HIPAA, PCI-DSS, and SOC 2 are built in — not bolted on. Every API gets unit tests, load tests, and a CI/CD pipeline on GitHub Actions.
CTOs who need to modernize legacy systems hire us. Product managers who need a scalable integration layer work with us. Startups raising Series A choose us for APIs that handle 10,000+ requests per second. We also build for healthcare, fintech, and logistics companies.
Types of software we ship.
REST API
Stateless, resource-oriented APIs using HTTP methods. Designed for mobile apps, web apps, and third-party integrations. JSON or XML responses.
GraphQL API
Single endpoint, query-language APIs. Clients fetch exactly what they need. Built with Apollo Server, TypeGraphQL, and DataLoader for N+1 prevention.
gRPC API
High-performance, binary-protocol APIs using Protocol Buffers. Ideal for microservices communication and real-time streaming. Supports HTTP/2.
WebSocket API
Full-duplex, persistent-connection APIs for real-time features: chat, live updates, multiplayer. Built with Socket.io or ws library.
Webhook Integration
Event-driven APIs that send data to URLs on triggers. Integrates with Stripe, Slack, GitHub, and custom systems. Retry logic and idempotency included.
Third-Party API Integration Layer
Unified gateway that abstracts multiple external APIs (Salesforce, HubSpot, Shopify) into one consistent interface. Caching and fallback built in.
API Gateway
Centralized entry point for microservices. Handles rate limiting, authentication, logging, and request transformation. Uses Kong, Traefik, or custom Go.
Microservices API
Distributed set of small, decoupled APIs each owning a business domain. Containerized with Docker, orchestrated with Kubernetes. Service mesh ready.
We build for every business type.

Why IRPR Is the Right API Development Vendor for Your Business
We deliver API projects on time and on budget because every engagement follows a repeatable process, not guesswork.
IRPR has shipped 200+ APIs across healthcare, fintech, ecommerce, and logistics. Our engineers average 12+ years of experience and have built APIs that handle millions of requests per day. We use the same tools and patterns that top tech companies use: Node.js, Go, Postgres, Redis, and Kubernetes.
Every API we build includes rate limiting, authentication, monitoring (Datadog/Prometheus), and auto-generated documentation. We also set up a CI/CD pipeline on GitHub Actions so you can deploy updates in minutes. Our APIs pass HIPAA, PCI-DSS, and SOC 2 audits without rework.
Generic API Agencies vs. IRPR: The Real Difference
Most agencies bill hourly and hand you code that breaks in production. IRPR delivers a production-ready API in 12 weeks for a fixed price.
Generic shops often rely on junior developers and reuse half-baked templates. They charge hourly, which means scope creep blows your budget. Their APIs lack monitoring, documentation, or security hardening. You are left with a codebase that needs immediate refactoring.
IRPR assigns only senior engineers (12+ years average) to every project. We start with a 2-week Roadmap phase that produces a fixed price and a detailed spec. We ship source code, CI/CD, monitoring, and documentation. Your API is ready for production on day one.
- Junior or mid-level developers
- Hourly billing - no budget cap
- No monitoring or alerting
- No CI/CD pipeline
- API documentation is an afterthought
- 10+ months to ship
- Senior engineers only (12+ years avg)
- Fixed price after 2-week Roadmap phase
- Datadog/Prometheus monitoring built in
- GitHub Actions CI/CD pipeline
- OpenAPI/Swagger docs auto-generated
- 8-12 weeks to production
Our 4-Phase API Development Process
Every project follows a structured process that removes ambiguity and delivers exactly what you need.
Phase 1: Discovery. We spend 1 week learning your domain, use cases, and constraints. We review your existing systems and data sources. You get a clear architecture diagram and a list of API endpoints.
Phase 2: Roadmap. In week 2 we create a detailed specification: endpoints, data models, authentication, rate limits, and integration points. You get a fixed price and a delivery timeline.
What Ships With Your API
You get more than just code. Every project includes everything needed to run, monitor, and scale the API.
Every API delivery includes source code in your private repository, a fully configured CI/CD pipeline, monitoring dashboards, and auto-generated documentation. We also include a load testing report and a security audit summary.
- Source code in your GitHub/GitLab repo (full ownership)
- CI/CD pipeline on GitHub Actions (deploy on push)
- API documentation (OpenAPI 3.0 / Swagger UI)
- Monitoring dashboard (Datadog or Prometheus + Grafana)
- Rate limiting and authentication (JWT / OAuth 2.0)
- Unit tests, integration tests, and load tests (k6 or Locust)
- Load testing report (requests per second, latency, error rate)
- Security audit report (OWASP top 10 checks, dependency scan)
- Deployment scripts for AWS, GCP, or Azure (Terraform or Pulumi)
- 30 days of production support and incident response
What we ship in this practice.
FHIR API for a Telemedicine Platform
We built a FHIR R4 compliant API that connects the platform to 50+ EHR systems. Reduced patient data retrieval time from 30 seconds to 0.8 seconds. Tech stack: Node.js, PostgreSQL, Redis, and HL7 FHIR SDK.
Payment Processing API for a Fintech Startup
We developed a PCI-DSS Level 1 certified API that processes $2M in daily transactions. Handles 15,000 requests per minute with 99.99% uptime. Tech stack: Go, Stripe Connect, PostgreSQL, and Prometheus.
Inventory API for an Ecommerce Marketplace
We created a real-time inventory API that syncs stock across 100+ warehouses and 3,000 vendors. Reduced overselling incidents by 95%. Tech stack: GraphQL (Apollo Server), Redis, Kafka, and Node.js.
Subscription Management API for a SaaS Platform
We designed a REST API that handles 500,000 active subscriptions with tiered pricing, usage metering, and proration. Integrated with Stripe Billing and Salesforce. Tech stack: Python (FastAPI), PostgreSQL, Celery.
Streaming API for a Media Company
We built a WebSocket API that delivers live captions and audience engagement data to 1M concurrent viewers. Latency under 200ms. Tech stack: Go, Redis Pub/Sub, WebRTC, and Kubernetes.
Tracking API for a Logistics Provider
We developed a gRPC API that processes 10M tracking events per day from GPS devices and warehouse sensors. Reduced package loss by 40%. Tech stack: gRPC, Go, Cassandra, and Apache Kafka.
Why teams hire us.
Fixed Price, Not Hourly Billing
Every 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
Our engineers average 12+ years of experience. No juniors, no subcontractors. Every person on your project has built and deployed APIs in production for at least 5 years.
Compliance Ready from Day One
We have built APIs that passed HIPAA, PCI-DSS, and SOC 2 audits on the first try. Security and compliance are part of our standard process, not an expensive add-on.
Async-First Project Management
We work across time zones (New York, Los Angeles, London, and more) with daily async updates via Slack and Loom. You get a weekly demo video every Friday. No micromanagement required.
12-Week Production MVP
Most teams deliver a working API in 12 weeks or less. We prioritize features ruthlessly and ship a production-grade MVP faster than agencies that overcomplicate the process.
Full Code Ownership
You own 100% of the source code, documentation, and IP from the start. No licensing fees, no ongoing royalties. We put the code in your repository on day 1 of the build phase.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
