We build APIs that connect your systems and scale with your business. IRPR ships production-ready APIs in 8-12 weeks with fixed pricing.
IRPR is the best custom API development consultant for companies that need secure, scalable integrations. We build REST, GraphQL, and SOAP APIs using Node.js, Python, Go, and .NET Core. Every API includes automated testing, rate limiting, and monitoring out of the box.
Our API projects ship in 8-12 weeks with fixed pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Each delivery includes full documentation, Postman collections, and a CI/CD pipeline.
CTOs hire us when they need a secure API to replace a deprecated legacy system. Product managers hire us to build a public API for their SaaS platform. Engineering leads hire us to integrate third-party services like Stripe, Salesforce, or HubSpot without breaking existing workflows.
Build stateless, cacheable REST APIs with JSON payloads. We use Express.js, FastAPI, or Spring Boot with OpenAPI 3.0 specs.
Design flexible GraphQL APIs that let clients query exactly what they need. We use Apollo Server, Hasura, or Yoga with schema stitching.
Build enterprise-grade SOAP APIs for legacy system integration. We support WSDL, XML schemas, and WS-Security for finance and healthcare.
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any third-party API. We handle OAuth 2.0, webhooks, and error retry logic.
Deploy a single entry point for all your microservices. We use Kong, AWS API Gateway, or NGINX with rate limiting and authentication.
Build real-time event-driven APIs that push data to your clients. We use AWS EventBridge, Zapier, or custom Node.js webhook handlers.
Audit your existing APIs for OWASP Top 10 vulnerabilities, broken authentication, and data exposure. We deliver a report with fixes within 2 weeks.
Generate interactive API docs with Swagger UI, Redoc, or Stoplight. We include Postman collections and SDK examples in 5 languages.
We ship production-ready APIs that connect your systems and scale with your business.
Every API we build starts with a 2-week Roadmap phase where we define endpoints, data models, authentication, and error handling. We use OpenAPI 3.0 specs to generate server stubs and client SDKs automatically. This cuts development time by 30% compared to writing code from scratch.
Our APIs handle 10,000+ requests per second on commodity hardware. We implement caching with Redis, rate limiting with token buckets, and monitoring with Datadog. Every API includes a health check endpoint, structured logging, and automated deployment via GitHub Actions.
Most API agencies promise flexibility but deliver delays and scope creep. IRPR does the opposite.
Generic dev shops start coding before the architecture is defined. They use hourly billing, which means you pay for their learning curve. They skip automated testing and leave you with undocumented endpoints that break on the next deploy.
IRPR starts with a fixed-price Roadmap that defines every endpoint, data model, and error code. We write tests before we write code. Every API ships with Postman collections, Swagger UI, and a deployment runbook. You own the source code from day one.
We follow a repeatable process that delivers a production-ready API in 8-12 weeks.
Each phase has clear deliverables and a fixed price. There are no surprises. You see progress every week through our shared project board.
The process works for REST, GraphQL, SOAP, and event-driven APIs. We adapt the timeline based on the number of endpoints and integration complexity.
Every API delivery includes everything you need to run, maintain, and extend your integration.
We don't just hand over code. You get a complete operational package that your team can use immediately. No missing pieces, no undocumented assumptions.
Our checklist is the same for every client. It covers security, monitoring, documentation, and deployment. Your team can extend the API without calling us for every change.
Built a REST API that handles subscription billing, invoicing, and refunds via Stripe. The API processes 5,000 transactions per day with 99.95% uptime. Tech stack: Node.js, Express, Stripe API, PostgreSQL, Redis.
Designed a GraphQL API for patient records, appointment scheduling, and video session metadata. Passed HIPAA audit on first attempt. Tech stack: Apollo Server, MongoDB, Twilio Video, Auth0.
Built a webhook-based API that syncs inventory across Shopify, Amazon, and their warehouse ERP. Reduced overselling by 95%. Tech stack: Python, FastAPI, AWS Lambda, Shopify API, Amazon SP-API.
Created a bidirectional REST API that syncs leads, contacts, and deals between the platform and Salesforce. Cut manual data entry by 8 hours per week per rep. Tech stack: Java Spring Boot, Salesforce REST API, RabbitMQ.
Developed a REST API that aggregates MLS listings from 20 sources and normalizes them into a single schema. Serves 2 million property records with sub-200ms response times. Tech stack: Go, PostgreSQL, Elasticsearch, Redis.
Built a SOAP API that integrates with a legacy banking core for identity verification and AML screening. Processes 10,000 verifications per month with 99.9% accuracy. Tech stack: .NET Core, SQL Server, Onfido API, JWT.
Every API project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices. Our average API project costs between $80K and $250K depending on endpoint count and integration complexity.
Every API is built by engineers with 10+ years of experience. We don't staff juniors or offshore teams. Our lead engineers have built APIs for Stripe, Salesforce, and Twilio integrations.
We write the API spec before we write any code. This gives you a complete contract that your frontend team can use immediately. We generate server stubs and client SDKs from the spec, cutting development time by 30%.
Every endpoint we build has unit tests, integration tests, and load tests. We enforce a minimum of 90% code coverage. Our CI pipeline blocks any deploy that drops below that threshold.
You own the source code, the API spec, and the documentation from day one. No licensing fees, no ongoing royalties. We hand over Postman collections, deployment runbooks, and a 30-day support period.
We build APIs that pass HIPAA, PCI-DSS, SOC 2, and FERPA audits. We implement encryption at rest and in transit, audit logging, and role-based access control by default. Our APIs have passed 10+ compliance audits without a single finding.
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.
