How this service works
Call when an agent needs link rel=search hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-search first.
Output
A list of href values from all <link rel='search'> elements found in the page or HTML provided, extracted in an SSRF-safe fashion. Returns an empty list if no such links are present.
Example use cases
Discover site search endpoint
“Look at https://en.wikipedia.org and extract any link rel=search hrefs — I want to know what search URL Wikipedia exposes in its page head.”
Parse search links from raw HTML
“I've got some raw HTML here and I need you to pull out all the link elements with rel=search and return their href values: <html><head><link rel="search" href="/opensearch.xml"/></head></html>”
Autodiscover OpenSearch for aggregator
“Can you check https://blog.mozilla.org and find any link rel=search hrefs it declares? I'm building a feed aggregator and need to discover their search endpoint automatically.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover the search interface of a public website via its link[rel=search] HTML metadata — common for OpenSearch autodiscovery. Prefer the free sandbox endpoint /v1/sandbox/profile-rel-search first to avoid the $0.005 USDC cost. Choose this paid endpoint when the sandbox is unavailable or when you need reliable production-grade SSRF-safe extraction.
Side effects
- URL is unreachable or returns non-200 response — extraction fails
- HTML exceeds 200,000 character limit — request rejected
- URL is blocked by SSRF safety rules (private/internal IP ranges) — request rejected
- Page has no link[rel=search] elements — returns empty result
- Malformed HTML causes parsing errors — may return partial or no results
- URL parameter is too short (< 8 chars) or too long (> 2048 chars) — validation error
