How this service works
Call when an agent needs link rel=amphtml hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-amphtml first.
Output
Returns the extracted href values from all link rel=amphtml elements found in the page or HTML, typically one or more AMP page URLs. If no amphtml link is present, returns an empty result or null.
Example use cases
Find AMP version of news article
“I need the AMP URL for this article — https://www.theguardian.com/technology/2024/ai-article — can you pull the link rel=amphtml href from that page?”
Check raw HTML for AMP alternate link
“I have this raw HTML from a webpage and I need you to extract any link rel=amphtml hrefs from it so I can redirect mobile users to the AMP version.”
SEO audit for AMP discoverability
“For this URL https://www.myblog.com/post/seo-tips, can you check if there's an amphtml link rel tag and tell me what AMP URL it points to?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-amphtml?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover the AMP alternate URL for a given public webpage, either by providing a URL to fetch or raw HTML to parse. It is SSRF-safe for agent use. If a free sandbox version (POST /v1/sandbox/profile-rel-amphtml) is available, prefer that first to avoid the $0.009 USDC charge.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with error
- Page has no link rel=amphtml elements — returns empty result
- HTML input exceeds 200,000 character limit — rejected with validation error
- URL is blocked due to SSRF protection (private/internal IPs) — rejected
- Malformed HTML prevents parsing — may return empty or partial result
- URL string shorter than 8 characters — rejected by schema validation
