How it works / How to use

Unified API gateway that routes requests to many LLM providers through one OpenAI-compatible interface with model routing, fallbacks, and usage tracking. OpenRouter supports hundreds of models via a single key.

  1. Create an account and API key in OpenRouter following the official docs.
  2. Pick the model endpoint that matches latency, cost, and capability needs.
  3. Prototype with a short prompt and log token usage.
  4. Add retries, timeouts, and content filters appropriate to your application.

How to prompt

OpenRouter fallbacks improve reliability across multiple upstream providers.

Design an OpenRouter setup that uses a cheap model for classification and a stronger model for final answers, with automatic fallback if the primary is down.

Best output tips

  • Set spend alerts where the dashboard allows.
  • Cache stable completions when safe to reduce cost.
  • Rotate API keys on a regular schedule.
  • Verify current plans and limits on the official OpenRouter website.
