How this service works
Call when an agent needs href attributes of //a via //a/@href from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/xpath-a-href first.
Output
A list of href attribute values extracted from all anchor tags found in the provided URL or HTML, deduplicated and SSRF-safe, covering both absolute and relative URLs present in the page.
Example use cases
Crawl outbound links from blog post
“Pull all the href URLs from the anchor tags on https://techcrunch.com/2024/05/01/ai-roundup/ — I want to see every link that article points to.”
Audit navigation links on a landing page
“Give me all the anchor href values from this HTML snippet I have — I need to audit which pages the nav menu links to.”
Discover linked resources on a documentation page
“Extract every href from the anchor tags on https://docs.python.org/3/library/os.html so I can see what other pages and external resources it references.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-a-href?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need href attributes from anchor tags extracted via XPath from a public page or raw HTML. Prefer this over CSS-selector or full-link extraction endpoints when you want precise XPath-based //a/@href queries. Use the free sandbox POST /v1/sandbox/xpath-a-href first if available; fall back to this paid endpoint at $0.009 USDC when the sandbox is unavailable or rate-limited.
Side effects
- URL is not publicly accessible or returns non-200 status
- HTML content exceeds 200,000 character limit
- URL is blocked for SSRF safety reasons (private/internal IPs)
- Malformed URL input (too short or too long)
- Page has no anchor tags, returning an empty list
- Network timeout when fetching the target URL
