How this service works
Call when an agent needs og:audio extracted from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/profile-og-audio first.
Output
Returns the value of the og:audio Open Graph meta property found in the page's HTML — typically a direct URL to an audio file. If no og:audio tag is present, the response will indicate an empty or null result. The extraction is performed in an SSRF-safe environment, so private or internal network addresses are blocked.
Example use cases
Podcast audio URL discovery
“I have a podcast episode page at https://podcasts.example.com/episodes/42 — can you extract the og:audio URL from it so I know what audio file is attached?”
Social share audio preview extraction
“I'm building a link preview tool. Given this HTML snippet, pull out the og:audio tag so I can show the correct audio player: <html><head><meta property='og:audio' content='https://cdn.example.com/audio.mp3'/></head></html>”
Bulk media metadata audit
“Check this article URL https://media.example.com/story/123 and tell me what og:audio value it has — I'm auditing whether our pages are correctly declaring their audio assets.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-og-audio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the og:audio Open Graph property from a public webpage or raw HTML, and want SSRF-safe server-side fetching without building your own HTML parser. Prefer the free sandbox endpoint (/v1/sandbox/profile-og-audio) for testing or non-production use; use this paid endpoint for reliable production extraction. Choose this over general-purpose HTML scrapers when you only need the og:audio field specifically and want a deterministic, low-cost single-purpose extraction.
Side effects
- URL is unreachable or returns a non-200 HTTP status — endpoint may return an error or empty result
- Page has no og:audio meta tag — result will be null or empty
- URL targets a private/internal network address — blocked by SSRF protection
- HTML input exceeds 200,000 character limit — request rejected
- URL exceeds 2,048 character limit — request rejected
- Malformed HTML may cause the parser to fail to locate the meta tag
