How this service works
Call when an agent needs nav anchor hrefs via nav a[href] from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/css-nav-href first.
Output
A list of href attribute values extracted from nav a[href] elements on the given page or HTML, representing the navigation link URLs found in the page's navigation sections.
Example use cases
Site navigation audit for SEO
“Pull all the navigation anchor links from https://acmecorp.com so I can audit their site structure and check for broken nav URLs.”
Scraping nav links from raw HTML
“I have this raw HTML snippet — can you extract all the href values from the nav elements in it so I can see where the navigation points?”
Building a site map from nav
“Go to https://myblog.io and get me all the hrefs in the nav bar — I want to build a quick site map of the main sections.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-nav-href?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract navigation anchor hrefs (nav a[href]) from a webpage or HTML fragment in an SSRF-safe way. Prefer the free sandbox POST /v1/sandbox/css-nav-href for testing or unpaid use. Choose this over general-purpose scraping tools when you only need nav-section links and want a lightweight, cost-predictable ($0.005 USDC) extraction without running your own browser or parser.
Side effects
- URL is not publicly accessible or returns non-200 status
- SSRF protection blocks private/internal IP ranges or localhost URLs
- HTML input exceeds 200,000 character limit
- No nav a[href] elements found — returns empty list
- Malformed URL or HTML causing parse failure
- Network timeout fetching the target URL
