How this service works
Call when an agent needs srcset attributes of //img via //img/@srcset from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/xpath-img-srcset first.
Output
Returns an array of srcset attribute values found in img elements on the given page or HTML, extracted via XPath (//img/@srcset). Each value is a raw srcset string that may contain multiple image URLs with width/density descriptors.
Example use cases
Audit responsive images on a webpage
“Go to https://mysite.com/products and pull out all the srcset attributes from the img tags so I can audit which responsive image sizes are being served.”
Extract srcset from pasted HTML
“I have this HTML snippet from a news article — can you find all the img srcset values in it so I can see what image resolutions they offer?”
Verify responsive image implementation
“Check https://brand.com/homepage and extract every img srcset attribute — I want to confirm they're properly implementing responsive images with multiple resolutions.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-img-srcset?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract srcset attributes specifically from img elements on a public page or HTML fragment, and the free sandbox endpoint (/v1/sandbox/xpath-img-srcset) is unavailable or has been exhausted. Prefer this over a general XPath endpoint when the task is specifically about responsive image sources.
Side effects
- URL is not publicly accessible or returns non-200 status
- HTML input exceeds 200,000 character limit
- No img elements with srcset attributes found — returns empty array
- SSRF-blocked URL (private IPs, internal hostnames) rejected for safety
- Malformed HTML may result in incomplete extraction
- URL string shorter than 8 characters or longer than 2048 characters rejected
