How this service works
Call when an agent needs og:image content via meta[property='og:image'] from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/css-meta-og-image first.
Output
Returns the value of the og:image meta property found in the page's HTML — typically an absolute image URL that the page declares for social sharing previews. If the page has no og:image tag, the response will indicate its absence.
Example use cases
Social preview image for shared link
“I'm building a link preview card — can you get the og:image URL from https://techcrunch.com/2024/01/15/some-article so I can show the right thumbnail?”
Scrape OG image from raw HTML
“I have the raw HTML of a product page here — can you extract the og:image meta tag value from it so I know what image it would show when shared on social media?”
Validate open graph image before publishing
“Before I schedule this post, can you check what og:image URL is set on https://myblog.com/new-post so I can confirm it'll have the right social preview image?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-meta-og-image?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract the og:image value from a public web page or a raw HTML snippet without paying for a full browser render. It is SSRF-safe, making it appropriate for agent pipelines where untrusted URLs might be submitted. If a free sandbox version at POST /v1/sandbox/css-meta-og-image is available, try that first to avoid the $0.007 USDC charge.
Side effects
- URL is unreachable or returns a non-200 status — fetch fails
- SSRF protection blocks private/internal IP ranges or localhost URLs
- HTML input exceeds 200,000 character limit — rejected
- No og:image meta tag present in the page — empty or null result
- Malformed URL input (under 8 or over 2048 characters) — validation error
- Page requires JavaScript rendering to populate meta tags — static fetch may miss dynamically injected tags
