How this service works
Call when an agent needs source srcset values extracted from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/profile-source-srcset first.
Output
Returns a list of srcset attribute values extracted from all <source> elements found in the given URL or HTML, capturing responsive image descriptors such as URLs paired with width descriptors (e.g. '1x', '2x', '800w') as defined in the page's markup.
Example use cases
Audit responsive images on a site
“Go to https://myshop.com/products and pull out all the srcset values from the source elements — I want to audit what responsive image sizes they're serving.”
Scrape srcset from pasted HTML
“I have this HTML snippet from a news article — can you extract all the srcset attribute values from any source elements in it so I can see which image resolutions are defined?”
Analyze competitor image strategy
“Check https://competitor.com/about and get me all the source srcset values — I'm trying to understand what image breakpoints and formats they're using for their responsive media.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-source-srcset?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract srcset attribute values from <source> elements in HTML or a public URL — particularly for auditing responsive images, analyzing media breakpoints, or processing picture/video source sets. Prefer this over generic CSS selector endpoints when you only need srcset values and want a purpose-built, SSRF-safe extractor. Try the free sandbox POST /v1/sandbox/profile-source-srcset first before paying $0.007 USDC per call.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- URL is blocked by SSRF safety rules (internal/private addresses) — access denied
- Page contains no <source> elements with srcset attributes — empty result returned
- Malformed HTML input prevents parsing — partial or empty results returned
- URL resolves to a redirect loop or timeout — error returned
