How this service works
Call when an agent needs href attributes of anchors under //nav via //nav//a/@href from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/xpath-nav-href first.
Output
Returns a list of href attribute values found in anchor tags under nav elements on the target page or HTML, extracted via the XPath expression //nav//a/@href. The response typically includes an array of URL strings representing navigation links.
Example use cases
Audit website navigation structure
“I need to audit the navigation structure of https://mybrand.com — can you extract all the href links from its nav elements so I can see what pages are linked in the menu?”
Build sitemap from nav links
“Grab all the nav anchor hrefs from this HTML I'm pasting so I can use them to build a sitemap: <html><nav><a href='/about'>About</a><a href='/contact'>Contact</a></nav></html>”
Monitor competitor navigation changes
“Extract all the navigation href links from https://competitor.com so I can compare them to last week's list and see if they've added or removed any menu items.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-nav-href?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to extract navigation link hrefs (//nav//a/@href) from a public webpage or raw HTML, and want an SSRF-safe hosted service rather than running XPath locally. Prefer the free sandbox POST /v1/sandbox/xpath-nav-href endpoint first; fall back to this paid endpoint ($0.002 USDC) when the sandbox is unavailable or quota-limited. Choose this over generic scraping APIs when you need precise XPath-scoped nav extraction without building your own parser.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML contains no nav elements or nav anchors — returns empty list
- SSRF-blocked URL (private IP ranges, localhost) — rejected with safety error
- HTML input exceeds 200,000 character limit — request rejected
- Malformed or invalid HTML — XPath may return partial or no results
- URL parameter too short (under 8 chars) or too long (over 2048 chars) — validation error
