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.
Stateless endpoints with JSON payloads. Uses Express.js or FastAPI. Includes rate limiting and auth via JWT.
Single endpoint that resolves nested queries. Built with Apollo Server or Yoga. Reduces frontend round trips by 40%.
Receive and send real-time events to Stripe, Shopify, or Slack. Uses Redis for retry logic and idempotency keys.
Abstract complex SaaS APIs behind a simple interface. Handles OAuth, pagination, and caching automatically.
Central router that aggregates data from multiple services. Built in Go or Node.js with gRPC for low latency.
Two-way sync between databases and external systems. Uses Kafka or RabbitMQ for change data capture.
Persistent connections for live dashboards and notifications. Built with Socket.io or WebSocket over TLS.
White-label API for partners with rate plans, API keys, and usage metrics. Supports Stripe billing integration.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
