Fetch a webpage and extract specific information using AI. Use this when you need one specific answer from a page (e.g. a price, a spec, contact info) rather than its full content. The answer comes back as text, not JSON. Costs 10 credits.
If the page has under 40 characters of text (empty or JavaScript-rendered body), the model is NOT called: content comes back empty, usage.low_content is true, and only 1 credit is charged, rather than a fabricated answer. A notice field then explains why. Gate on usage.low_content (or usage.content_chars) to detect pages you cannot ground on.
Returns: content (the extracted text), url, credits_used, credits_remaining, usage (input_tokens, output_tokens, content_chars, low_content), notice (null unless there was no answer).
Args:
url: The URL to extract from
prompt: What information to extract (e.g. "list all pricing tiers with features" or "extract the author name and publication date")
