How this service works
Call when an agent needs og:image:width extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-og-image-width first.
Output
Returns the value of the og:image:width Open Graph meta tag extracted from the given URL or HTML content. Typically a numeric string representing pixel width (e.g. '1200'). May be null or empty if the tag is absent.
Example use cases
Social preview image dimension check
“What is the og:image:width declared on https://myblog.com/post/launch-announcement? I want to make sure the Open Graph image width is set correctly for social sharing.”
Validate OG metadata from raw HTML
“I have the HTML source of a product page — can you pull out the og:image:width value from it so I can verify the Open Graph width is declared?”
Audit OG image width across pages
“Check https://shop.example.com/product/42 and tell me the og:image:width meta tag value — I'm auditing our product pages to confirm OG image dimensions are set.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-og-image-width?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need only the og:image:width value from a page's Open Graph metadata and want SSRF-safe URL fetching included. Prefer the free sandbox endpoint (/v1/sandbox/profile-og-image-width) for testing or non-production use. Choose this paid endpoint for production agent workflows where SSRF protection and reliability matter.
Side effects
- URL is not publicly accessible or returns a non-200 status — extraction fails
- No og:image:width meta tag present in the page — returns empty or null result
- HTML input exceeds 200,000 character limit — request rejected
- URL string shorter than 8 characters or longer than 2048 characters — validation error
- SSRF-blocked URL (private IP, localhost, internal network) — request rejected for safety
