leading api development vendorapi development
We ship production-grade APIs for B2B platforms, fintech, and healthcare. You get full ownership, no lock-in, and a fixed price from day one.
IRPR is a leading API development vendor. We build REST, GraphQL, and gRPC APIs using Node.js, Go, Python, and PostgreSQL. Every API ships with OpenAPI 3.0 docs, rate limiting, and automated tests.
Our delivery process runs 8 to 12 weeks for an MVP. Fixed pricing starts at $80K and goes to $250K depending on complexity. We support HIPAA, PCI-DSS, SOC 2, and FERPA compliance out of the box.
CTOs hire us when they need a scalable API layer for their SaaS product. Fintech founders use us to build compliant payment APIs. Healthcare startups trust us with their HIPAA-bound patient data integrations. Platform teams call us to replace unreliable internal APIs with a clean, documented system.
Types of software we ship.
REST API development
Resource-oriented endpoints with JSON payloads. We use Express.js, Fastify, or Go Fiber. Includes JWT auth and Sentry monitoring.
GraphQL API development
Single endpoint with flexible queries. Built with Apollo Server or Hasura. Reduces over-fetching for mobile and web clients.
gRPC API development
High-performance bi-directional streaming using Protocol Buffers. Ideal for microservices communication in Kubernetes environments.
Third-party API integration
Connect your system to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP endpoint. We handle pagination, retries, and webhooks.
Payment API development
Build PCI-DSS compliant payment flows with Stripe, Braintree, or Adyen. Supports subscriptions, invoicing, and refunds.
Healthcare API development
HIPAA-compliant endpoints for EHR, FHIR, and patient portals. We use SMART on FHIR standards and AWS HealthLake.
Real-time API development
WebSocket or Server-Sent Events for live dashboards, chat, and notifications. Powered by Socket.IO, Redis Pub/Sub, and AWS API Gateway.
API gateway & proxy development
Centralize auth, rate limiting, and logging with Kong, NGINX, or AWS API Gateway. One entry point for your microservices.
We build for every business type.
SaaS platforms
Fintech companies
Healthcare organizations
Ecommerce brands
Logistics & supply chain
Why choose a leading API development vendor
Hiring a generic freelancer or a junior team often leads to inconsistent designs and security gaps.
IRPR has shipped 200+ production APIs across 10 industries. Every project starts with a 2-week Roadmap phase where we define endpoints, data models, and auth flows. We write the code, deploy it, and hand over full ownership.
Our APIs average 99.9% uptime on production. We enforce standardized error handling (RFC 7807), structured logging (Structured JSON), and automated canary deployments. You get a clean, documented system you can extend on your own.
The difference between a random dev shop and a leading API development vendor
Not every agency delivers a secure, documented, production-ready API. Here is what separates IRPR from the rest.
When you work with a generic dev shop, you often get undocumented endpoints, no CI/CD pipeline, and a single point of failure. We see projects where the API crashes under 100 concurrent users or exposes PII through poorly scoped tokens.
IRPR treats your API as a product. We write integration tests, set up staged deployments, and include a runbook for your operations team. The result is an API that scales from day one and passes any compliance audit.
- No OpenAPI spec delivered
- Hardcoded secrets in config files
- No test coverage beyond 20%

- OpenAPI 3.0 spec with every project
- Secrets in AWS Secrets Manager or HashiCorp Vault
- 90%+ test coverage on all critical paths
- Database with proper indexes and read replicas
- Rate limiting via NGINX or API Gateway
- Full documentation and team handoff
How we build your API in 8-12 weeks
Our process is structured so you see progress every week. No black box, no surprises.
We follow a four-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and go/no-go gates. You decide when to proceed.
By week 12, you have a fully documented, tested, and deployed API. Your team can take over maintenance, or we can stay on for ongoing support. It is your code, your license, your choice.
What ships with every API project
You are not just paying for code. You get a complete production-ready package.
Every API project from IRPR includes infrastructure-as-code, monitoring, and a handoff session. You can onboard a new developer in one afternoon.
All deliverables are in your repo from day one. No data stored on our servers, no third-party NDA workarounds.
- Source code in your private GitHub or GitLab repo
- OpenAPI 3.0 (Swagger) documentation
- CI/CD pipeline using GitHub Actions or GitLab CI
- Dockerized microservices with docker-compose for local dev
- Sentry error tracking and APM (Application Performance Monitoring)
- Automated integration tests with 90%+ coverage
- Terraform or CloudFormation scripts for infrastructure
- Postman or Insomnia collection for manual testing
- Runbook with deploy, rollback, and incident procedures
- 2-hour handoff session with your engineering team
What we ship in this practice.
Payment processing API for a fintech startup
We built a PCI-DSS compliant payment API using Stripe Connect, Node.js, and PostgreSQL. The client reduced failed transactions by 35% and onboarded 200+ merchants in the first quarter. Tech stack: Stripe, Express.js, TypeScript, AWS ECS.
EHR integration API for a telehealth platform
We developed a FHIR-based API connecting a telehealth app to Epic and Cerner systems. The client eliminated 8 hours of manual data entry per provider per week. Tech stack: SMART on FHIR, Python, Flask, AWS HealthLake.
Real-time inventory API for an ecommerce brand
We built a WebSocket API that syncs inventory across 50+ warehouses and 3 Shopify stores. The client reduced overselling incidents by 98% during Black Friday 2023. Tech stack: Socket.IO, Redis, Node.js, AWS ElastiCache.
Multi-tenant CRM API for a B2B SaaS provider
We delivered a GraphQL API with row-level security for a CRM platform. The client scaled from 100 to 5,000 users in 6 months without database performance degradation. Tech stack: Apollo Server, Hasura, PostgreSQL, Google Cloud Run.
Fleet tracking API for a logistics company
We created a gRPC-based API that ingests GPS data from 10,000+ devices every 30 seconds. The client cut route planning time by 40% and reduced fuel costs by 12%. Tech stack: Go, gRPC, Kafka, TimescaleDB, AWS EKS.
Student data API for an edtech platform
We built a FERPA-compliant REST API that syncs enrollment, grades, and attendance from 5 different school districts. The client reduced manual reporting time by 15 hours per week per district. Tech stack: Django REST Framework, Python, PostgreSQL, AWS RDS.
