The previews use only what you type. To read the tags a live page already has, copy the agent prompt on this page. Runs in your browser, nothing is sent anywhere except the image request to the host you typed.

Run it from your agent

Copy one prompt, give it to your agent.

Fill in the placeholder, paste it, and the agent runs the same job with current data on your looot account and shows the cost.

You give it: a title, description, image url and site name.
Billed per call, nothing while your agent is idle.
The agent shows the price before it calls.

Prompt: Open Graph preview

Search the catalog for a web page to markdown endpoint that returns page metadata and check its price before you call. 3. Read the og:title, og:description, og:image and twitter: tags. 4.
