OpenRouter
PaidInference & Routing
A single account and API for every model.
What it’s for
OpenRouter routes requests to OpenAI, Anthropic, Google, Meta, Mistral and hundreds of other models behind one OpenAI-compatible API, with unified pay-as-you-go billing and automatic fallback between providers when one is down.
How to use it
Create an account, add credits, and use the OpenAI SDK with a different base URL — that is the whole integration. Use their playground to compare models and pricing side by side before you commit.
Pricing
Pay-as-you-go credits. Pricing mirrors provider rates plus a small fee on top.
