How this service works
Call when an agent needs twitter:card extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-twitter-card first.
Output
Returns the extracted twitter:card meta tag values found in the page or HTML, including card type (e.g. summary, summary_large_image), title, description, image URL, site handle, and other twitter: prefixed meta properties present in the document.
Example use cases
Social preview audit for a website
“Check https://techblog.example.com/launch-post and extract all the twitter:card meta tags so I can see how the article will appear when shared on X/Twitter.”
SEO metadata validation pipeline
“I have this HTML snippet from our product page — can you parse it and extract any twitter:card metadata so I can verify the title, description, and image are set correctly?”
Competitive research on social metadata
“Extract the twitter:card information from https://competitor.com/pricing — I want to know what card type they're using and what title and image they've set for social sharing.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-twitter-card?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to reliably extract twitter:card metadata from a public URL or raw HTML without building your own scraper. Prefer the free sandbox POST /v1/sandbox/profile-twitter-card first; fall back to this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over generic scraping tools when you specifically need structured twitter: meta tag extraction with SSRF safety guarantees.
Side effects
- URL is not publicly accessible or returns non-200 status
- SSRF check blocks private/internal IP ranges or localhost URLs
- HTML input exceeds 200,000 character limit
- No twitter:card meta tags found in the page
- URL parameter too short (< 8 chars) or too long (> 2048 chars)
- Payment of $0.002 USDC not provided or rejected
