How this service works
Call when an agent needs anchor hrefs via a[href] from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/css-a-href first.
Output
A list of all href attribute values found in anchor tags on the given page or HTML, extracted using the CSS selector a[href]. Returns strings such as relative paths, absolute URLs, or mailto/tel links present in the document.
Example use cases
Crawl outbound links from article
“Get all the hyperlinks from https://techcrunch.com/2024/05/01/ai-roundup so I can see which sites this article references.”
Extract nav links from raw HTML
“I have this HTML snippet — can you pull out all the anchor hrefs from it so I know what the navigation menu links to?”
Audit internal links on a product page
“Fetch all the anchor links from https://myshop.com/products/widget so I can check which pages it links to internally.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-a-href?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need only the anchor href values from a page and want SSRF-safe fetching for a small per-call cost. Prefer the free sandbox POST /v1/sandbox/css-a-href first if available; use this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over generic scraping endpoints when you specifically need link/href extraction via CSS selector without additional overhead.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- SSRF-blocked URL (private IP ranges, localhost) — rejected before fetching
- HTML input exceeds 200,000 character limit — request rejected
- No anchor tags found on page — returns empty list
- Malformed HTML may result in incomplete or unexpected href extraction
