How this service works
Call when an agent needs link rel=stylesheet hrefs extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-rel-stylesheet first.
Output
A list of href attribute values from all link[rel=stylesheet] elements found in the fetched page or provided HTML, representing external and inline CSS file references.
Example use cases
Audit CSS dependencies of competitor site
“Pull all the stylesheet links from https://www.competitor.com so I can see which CSS frameworks and fonts they're loading.”
Inspect stylesheets from raw HTML snippet
“I have this HTML from a scraped page — can you extract all the link rel=stylesheet hrefs from it so I can see what CSS files it references?”
Inventory stylesheets for design system migration
“Go to https://legacy.mycompany.com and extract every CSS stylesheet URL linked in the page so I can document them before we migrate to a new design system.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-rel-stylesheet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically enumerate CSS stylesheet link references from a webpage or HTML blob in an SSRF-safe environment. Prefer the free sandbox variant (POST /v1/sandbox/profile-rel-stylesheet) for testing. Choose this over general HTML scrapers when you only need stylesheet hrefs and want a focused, low-cost extraction without parsing all link tags yourself.
Side effects
- URL is unreachable or returns a non-200 status — no hrefs returned
- Page blocks the crawler with bot-detection or firewall — empty or error result
- SSRF-safe filter blocks private/internal IP ranges — request rejected
- HTML input exceeds 200,000 character limit — request rejected
- No link[rel=stylesheet] elements present on the page — returns empty list
- Malformed URL input (under 8 or over 2048 characters) — validation error
