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
