How this service works
Call when an agent needs twitter:description extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-twitter-description first.
Output
Returns the extracted twitter:description meta tag content as a string from the target URL or provided HTML. If the tag is absent or the page is unreachable, returns an empty result or error indicator.
Example use cases
SEO audit for competitor pages
“Fetch the twitter:description tag from https://competitor.com/about so I can compare their social preview text with ours.”
Content enrichment for link previews
“I have the raw HTML for a scraped news article — can you pull out the twitter:description value so I can use it as the preview snippet?”
Brand monitoring metadata check
“Check https://mybrand.io and tell me what the twitter:description says — I want to make sure our Twitter card description is showing the right text.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-twitter-description?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need specifically the twitter:description meta tag value from a page, rather than the general og:description or plain meta description. It is useful for social media preview auditing, SEO tooling, and content enrichment pipelines. Prefer the free POST /v1/sandbox/profile-twitter-description endpoint for testing before incurring the $0.004 USDC charge.
