Web fetch

How it works

For reading a specific page or PDF, like a link in the prompt or documentation to summarize.

1. 1

   Your model requests the URL of a page or PDF it needs to read.

2. 2

   OpenRouter fetches it with the configured engine and extracts the readable text.

3. 3

   Your model uses the content in its answer, and can fetch more URLs.

Providers and pricing

The default engine, auto, uses the model provider’s native fetch when the model supports it and falls back to Exa otherwise.

Standard model token costs apply to every request.
