How this service works
Call when an agent needs document title text via title from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/css-title first.
Output
Returns the extracted text content of the HTML <title> element from the given URL or HTML input. Typically a short string representing the page's document title.
Example use cases
Verify webpage title for SEO audit
“I have this list of URLs and I need to know what their HTML title tags say — can you start with https://mybrand.com/landing-page and tell me the exact document title?”
Extract title from raw HTML snippet
“I have some raw HTML from a page I scraped earlier — can you pull out the document title from it? Here's the HTML: <!DOCTYPE html><html><head><title>My Product Launch</title></head><body>...</body></html>”
Confirm article headline matches title tag
“Can you fetch the page title from https://techcrunch.com/2024/05/01/some-story and tell me if it matches the headline I have on file?”
