How this service works
Call when an agent needs image srcset values via img[srcset] from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/css-img-srcset first.
Output
A list of srcset attribute values extracted from all img elements found in the provided URL or HTML, reflecting the responsive image candidates declared on the page.
Example use cases
Audit responsive images on a landing page
“I want to audit the responsive image setup on https://www.acmecorp.com — can you extract all the img srcset values so I can see what image candidates they're declaring?”
Extract srcset from pasted HTML snippet
“Here's some HTML I copied from a page — can you parse it and pull out all the img srcset attribute values for me? <img srcset='image-320w.jpg 320w, image-480w.jpg 480w, image-800w.jpg 800w'>”
Check competitor image asset strategy
“Can you fetch https://www.competitor.com/products and extract all the img srcset attributes? I want to understand what image sizes and resolutions they're targeting.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-img-srcset?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically extract img[srcset] attribute values from a public webpage or HTML fragment for responsive image analysis. It is SSRF-safe, making it appropriate for agent-driven workflows where untrusted URLs may be passed. Prefer the free sandbox endpoint (/v1/sandbox/css-img-srcset) for testing before paying $0.008 USDC per call.
Side effects
- URL is private or SSRF-blocked — request rejected for security reasons
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- No img[srcset] attributes found on the page — returns empty result
- Malformed HTML may result in incomplete or missing srcset values
