I will build a multi llm API gateway with automatic failover
Achuur Mo
About this gig
Are you relying on a single LLM API and suffering from rate limits, 503 downtime, or skyrocketing token costs?
I build production-grade Multi-LLM API Gateways in Node.js / TypeScript that automatically route requests and failover across multiple providers (Anthropic Claude, Google Gemini, OpenAI, OpenRouter).
What I Deliver:
Automatic Failover: If Claude fails or hits limits, requests instantly switch to Gemini or DeepSeek with zero downtime.
Cost Optimization: Route simple tasks to 30x cheaper models (Gemini Flash) while keeping premium models for complex reasoning.
Real-Time Logging: Track prompt/completion token usage and cost per call.
️ Production-Ready Code: Clean TypeScript/Node.js architecture, environment security (.env), and unit tests (npm test).
What's Included:
Custom Node.js / Express / Fastify Server
Multi-Provider Failover Router & Retry Logic
Token & Cost Estimator Middleware
Comprehensive README, Test Suite & Postman Collection
Why Choose Me?
Clean, documented code ready for Docker / Cloud Run deployment
100% test-backed deliveries
14 days post-delivery support guarantee
Stop letting API outages crash your SaaS app! Message or order now to get started.

FAQ
What do I need to provide to get started?
A brief overview of your application workflow and API keys for the providers you wish to connect (or I can use mock test keys for initial development).
How does the automatic failover work?
If the primary provider returns a 500/503 HTTP error or rate limit status, the gateway automatically redirects the payload to the secondary provider within milliseconds without crashing your app.
Will I receive the full source code and unit tests?
Yes! Every package includes the complete source code repository, clean inline comments, environment setup instructions, and runnable unit tests (npm test).
