How this service works
Call when an agent needs link rel=prev hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-prev first.
Output
Returns the extracted href value(s) from any link elements with rel=prev found in the provided URL's page or the supplied raw HTML. If no rel=prev link is present, the response will indicate absence. The result enables agents to navigate paginated content backwards or verify SEO pagination signals.
Example use cases
Crawl paginated blog archives
“I'm traversing a blog archive and need to walk backwards through all pages. Can you extract the rel=prev href from https://myblog.com/posts?page=5 so I can follow the pagination chain?”
Parse prev link from raw HTML
“I've got some HTML from a news site's article listing page and I need to pull out the link rel=prev href value — here's the HTML: <html><head><link rel='prev' href='/articles?page=2'/></head><body>...</body></html>”
SEO pagination audit
“I'm auditing pagination signals on a site. Can you fetch the rel=prev link from https://shop.example.com/products?page=4 so I can verify the previous-page relationship is correctly declared?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-prev?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reliably extract rel=prev pagination links from either a live public URL or raw HTML content, especially in SSRF-safe contexts. Prefer the unpaid sandbox at POST /v1/sandbox/profile-rel-prev for testing before committing the $0.004 USDC per-call cost. Use this over general-purpose scraping tools when you specifically need link relation extraction without storing data.
Side effects
- URL is unreachable or returns a non-200 status — fetch fails with an error
- No rel=prev link found in the page or HTML — returns empty or null result
- HTML input exceeds 200,000 character limit — request rejected
- URL blocked due to SSRF safety restrictions (private IPs, localhost) — returns SSRF guard error
- Malformed URL input below minimum length — validation error
