## 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-aria-label-extractor-ee3654df -d '<json body>'
```

Example prompt: Can you extract all the aria-label values from https://example.com so I can audit its accessibility attributes?

## When to prefer this

Use this endpoint when you need to programmatically extract aria-label accessibility attributes from a public webpage or HTML snippet and want a hosted, SSRF-safe service rather than running your own parser. It is well-suited for accessibility audits, automated UI testing, or competitive analysis of accessible labeling. Prefer the free sandbox variant (/v1/sandbox/profile-aria-label) for development and testing before committing to the paid version.

## Known failure modes

- URL points to a private/internal IP address — rejected due to SSRF protection
- HTML input exceeds 200,000 character limit — request rejected
- URL is malformed or shorter than 8 characters — validation error
- Target URL is unreachable or returns non-2xx status — fetch failure
- No aria-label attributes found — returns empty result set
- Payment of $0.007 USDC not provided or insufficient — 402 Payment Required

## How this service works

Call when an agent needs aria-label values extracted from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/profile-aria-label first.

## Output

Returns a list or collection of aria-label attribute values found within the provided HTML or fetched from the given public URL, enabling the caller to audit, compare, or process accessibility labels programmatically.
