# OpenRouter Multi-Provider

## Overview

OpenRouter's unified API lets you access models from OpenAI, Anthropic, Google, Meta, Mistral, and others with a single API key and endpoint. Model IDs use `provider/model-name` format. The same OpenAI SDK code works for any provider by simply changing the model ID. This skill covers provider comparison, cross-provider routing, feature normalization, and BYOK (Bring Your Own Key).

## Prerequisites

- A single OpenRouter API key exported as `OPENROUTER_API_KEY` — it covers every provider (OpenAI, Anthropic, Google, Meta, Mistral); see the `openrouter-install-auth` skill for setup
- `curl` and `jq` for the provider-landscape query
- Python 3.8+ with the OpenAI SDK (`pip install openai`)
- For BYOK only: your own provider API key (e.g. an OpenAI key) added in the OpenRouter dashboard under Settings > Integrations > Add Provider Key
