How this service works
Call when an agent needs fb:app_id extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-fb-app-id first.
Output
Returns the extracted fb:app_id value found in the page's meta tags (e.g. the numeric Facebook App ID string), or an empty/null result if no fb:app_id is present. The endpoint fetches the URL safely (SSRF-protected) or parses provided HTML directly.
Example use cases
Competitive intelligence on Facebook integrations
“Look up https://www.nike.com and tell me what Facebook App ID they're using in their page head — I want to see which Facebook app they've connected to their site.”
Auditing client website Facebook setup
“I have the HTML source of my client's homepage here — can you pull out the fb:app_id value from it so I can verify their Facebook pixel is set up correctly?”
Bulk site analysis for Facebook presence
“Check https://www.etsy.com and extract their fb:app_id meta tag — I'm building a spreadsheet of which e-commerce platforms have Facebook apps configured.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-fb-app-id?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract the fb:app_id Open Graph meta property from a public webpage or known HTML snippet. Prefer the free sandbox endpoint (/v1/sandbox/profile-fb-app-id) for testing before using this paid version. Choose this over general HTML scrapers when you need a targeted, SSRF-safe extraction of specifically the Facebook App ID without processing the full DOM yourself.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- Page has no fb:app_id meta property — returns empty or null result
- URL points to a private/internal IP address — rejected by SSRF protection
- HTML input exceeds 200,000 character limit — request rejected
- Malformed URL input — validation error returned
- Page uses JavaScript rendering to inject meta tags — statically parsed content may miss dynamically injected fb:app_id
