affordable custom api development vendorAPI Development
Build APIs that move your product forward. Fixed pricing from $50K without hidden costs.
IRPR builds custom APIs for web apps, mobile backends, and third-party integrations. We use Node.js, Python, Go, and Postgres to deliver high-performance endpoints. Every API follows OpenAPI 3.0 specs for clear documentation.
Our affordable custom api development vendor model offers fixed pricing from $50K to $200K. Delivery takes 8 to 12 weeks. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
CTOs scaling a SaaS product hire us to replace fragile integrations. Startup founders commission an MVP API in weeks. Enterprise teams use us to build microservices gateways that connect legacy systems. All get a dedicated senior engineer and a fixed quote.
Types of software we ship.
REST API Development
Stateless endpoints with JSON payloads. Uses Express.js or FastAPI. Includes rate limiting and auth via JWT.
GraphQL API Development
Single endpoint that resolves nested queries. Built with Apollo Server or Yoga. Reduces frontend round trips by 40%.
Webhook Integration
Receive and send real-time events to Stripe, Shopify, or Slack. Uses Redis for retry logic and idempotency keys.
Third-Party API Wrapper
Abstract complex SaaS APIs behind a simple interface. Handles OAuth, pagination, and caching automatically.
Microservices Gateway

Why IRPR Works as an affordable custom api development vendor
We ship working APIs fast because our process removes guesswork.
IRPR has shipped over 200 products across 50 countries. Every project starts with a 2-week Roadmap phase where we define the contract and endpoints. You get a fixed price before a single line of code is written. No hourly billing, no scope creep.
Our engineers average 10+ years of experience. They work in US-friendly time zones with 4-hour overlap. We use GitHub Actions, Docker, and AWS EC2 to deploy. Every API includes Sentry error monitoring and Datadog dashboards.
affordable custom api development vendor vs generic dev shops
The difference is in how we scope, build, and deliver.
Generic shops write vague proposals, bill hourly, and hand you code that barely works. IRPR delivers a fully documented API with tests, CI/CD, and monitoring inside 12 weeks.
We also own the contractual outcome. If we miss a spec, we fix it at no extra cost. Our fixed-price model ends the surprise invoices that plague custom API projects.
- Hourly billing with no cap
- Junior developers learning on your dime
- No written API contract
- Deliverable is a zip file of code
- Zero monitoring or alerting
- You own nothing until final payment
- Fixed price agreed in week 2
- Senior engineers only (10+ years avg)
- OpenAPI 3.0 contract before build
- Git repo with automated CI/CD
- Sentry + Datadog pre-configured
- Full code ownership from day one
How IRPR builds your custom API in 4 phases
Every project follows the same framework to eliminate risk.
Phase 1 is the Idea – we clarify your use case and data sources. Phase 2 is the Roadmap – we write the API contract, choose the stack, and fix the price. Then we enter Product (build) and Release (deploy + handover).
The timeline is 8–12 weeks from kickoff to production. You get daily updates in a shared Slack channel. All source code is in your GitHub repository from sprint one.
What ships when you hire IRPR as your affordable custom api development vendor
Every engagement includes these deliverables by default.
You get a production-ready API that your frontend and third parties can consume immediately. No hidden handoffs, no missing pieces.
All code is stored in your private GitHub repo. We also provide a Postman collection and a Markdown readme so your team can integrate in hours, not weeks.
- Source code in your GitHub repository
- OpenAPI 3.0 specification document
- CI/CD pipeline with GitHub Actions
- Unit and integration tests (80%+ coverage)
- Docker Compose for local development
- Deployment scripts for AWS ECS or Heroku
- Sentry error tracking and Datadog monitoring
- Rate limiting and JWT authentication
What we ship in this practice.
REST API for SaaS Integration Platform
A SaaS startup needed to sync customer data between HubSpot and Salesforce. IRPR built a REST API with background jobs in BullMQ. Reduced manual data entry by 12 hours per week. Tech: Node.js, Express, Postgres, Redis.
GraphQL API for Ecommerce Frontend
An ecommerce company wanted a single endpoint to resolve product, inventory, and reviews. IRPR delivered a GraphQL API with Apollo Server. Page load time dropped by 60%. Tech: Apollo Server, MongoDB, Redis cache.
Webhook Integration for Payment Automation
A fintech firm needed to receive Stripe events and adjust subscription statuses. IRPR built a webhook handler with idempotency keys. Missed events went to zero. Tech: Python, FastAPI, Stripe API, Celery.
Microservices Gateway for Fintech Platform
A lending platform had 9 microservices and wanted a unified API. IRPR built a gateway in Go with gRPC. Response time improved from 400ms to 90ms. Tech: Go, gRPC, Envoy, Prometheus.
Data Sync API for Healthcare System
A hospital needed to sync patient records between EHR and lab system. IRPR built a HIPAA-compliant sync API with change data capture. Error rate fell from 5% to 0.5%. Tech: Kafka, Java Spring Boot, Postgres, FHIR.
Real-Time API for Logistics Tracking
A logistics company wanted live driver locations in their client dashboard. IRPR delivered a WebSocket API with Socket.io. Tracking latency went from 30 seconds to under 2 seconds. Tech: Node.js, Socket.io, Redis, Google Maps API.
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 total cost before we write a single endpoint.
Senior engineers only
Our developers average 10+ years of experience. We do not staff juniors or offshore teams. This means your API ships with fewer bugs and cleaner code from day one.
HIPAA, PCI, and SOC 2 compliance
We build APIs that meet regulatory standards for healthcare (HIPAA), payments (PCI-DSS), and SaaS (SOC 2). We encrypt data at rest and in transit, and your infrastructure is isolated.
8 to 12 week delivery
Our framework (Idea, Roadmap, Product, Release) ensures a production-ready API in 2 to 3 months. Faster than agencies that take 6 months for the same scope.
Full code ownership
You own every line of code from day one. We put it in your GitHub repo, not ours. No licensing fees, no vendor lock-in, no monthly retainers.
Async-first communication
We work asynchronously across 4-hour overlap with US time zones. You get a Slack channel, daily status updates, and a Trello board. No pointless meetings, just progress.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
