How this service works
Call when an agent needs nofollow anchor hrefs via a[rel~='nofollow'] from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/css-nofollow first.
Output
A list of href values extracted from all anchor elements matching a[rel~='nofollow'] found either by fetching the given URL or parsing the provided HTML string. Returns an array of URL strings representing the nofollow links on the page.
Example use cases
SEO nofollow audit on a page
“Grab all the nofollow anchor links from https://techblog.example.com/article/2024-review — I want to see which outbound links they've marked as nofollow for SEO purposes.”
Detect sponsored links in raw HTML
“Here's the HTML of a press release page — can you find every link that has rel=nofollow so I can see which ones are being treated as paid or untrusted?”
Competitive backlink analysis
“Go to https://competitor.example.com/resources and list all the hrefs from anchor tags that have rel=nofollow — I'm trying to understand their link-building strategy.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-nofollow?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract rel=nofollow anchor links from a page, either by URL or raw HTML, and want an SSRF-safe, deterministic CSS-selector-based extraction without involving an LLM. Prefer the unpaid sandbox endpoint (POST /v1/sandbox/css-nofollow) for testing. Choose this over a general scraper when you only need nofollow links and want a cheap, focused extraction at $0.001 USDC.
Side effects
- URL is unreachable or returns non-200 status — fetch fails with an error
- URL is blocked by SSRF protection (private/internal IP ranges) — returns SSRF error
- HTML input exceeds 200,000 character limit — returns validation error
- No nofollow links found on the page — returns empty array
- Malformed HTML may result in incomplete or no extraction
- URL string shorter than 8 characters or longer than 2048 characters — returns validation error
