## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentshelf-xpath-img-srcset-extractor-eb727277 -d '<json body>'
```

Example prompt: Can you extract all the srcset attributes from the img tags on https://example.com/gallery — I need to see what responsive image sources they're using?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
