How this service works
Call when an agent needs twitter:image extracted from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/profile-twitter-image first.
Output
Returns the value of the twitter:image meta tag found in the page or HTML — typically an absolute URL pointing to the social preview image declared by the site.
Example use cases
Social preview audit for a blog
“Pull the twitter:image from https://myblog.example.com/posts/launch-day so I can see what image shows up when someone shares that article on Twitter.”
Scraping image from provided HTML
“I have the raw HTML of a product page — can you extract the twitter:image meta tag from it so I know what social preview image it declares?”
Brand monitoring for link sharing
“Check what twitter:image is set on https://competitor.example.com/homepage — I want to see what image they're using for their Twitter card preview.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-twitter-image?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract the twitter:image meta tag from a public URL or raw HTML snippet, especially in agent workflows that audit social previews, validate link sharing images, or enrich content metadata. Prefer the free sandbox endpoint (/v1/sandbox/profile-twitter-image) when available; use this paid endpoint when sandbox is unavailable or rate-limited.
Side effects
- No twitter:image tag present in the page or HTML — returns empty or null result
- URL is unreachable or returns non-200 status — fetch fails
- SSRF-blocked URL (private IP ranges, localhost) — rejected for security reasons
- HTML exceeds 200,000 character limit — input truncated or rejected
- URL exceeds 2,048 character limit — input rejected
- Malformed HTML with no parseable meta tags — no result returned
