## 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 option-labels-empty-value-report-2af37683 -d '<json body>'
```

Example prompt: Can you check this product page HTML for any <option> elements with the id attribute set to 'sample' that have empty label text? The HTML is: <!doctype html><html><head></head><body><select><option id="sample">Example product guide</option></select></body></html> — I'm looking for empty values related to the term 'product'.

## When to prefer this

Choose this endpoint when you need a lightweight, static-parse check for empty option label text in HTML select elements — particularly when you already have the HTML or a simple public URL, and you do not need JavaScript rendering. It is purpose-built for auditing dropdown option labels rather than general HTML extraction or full accessibility scanning.

## Known failure modes

- URL is unreachable or returns non-200 status — no content to parse
- HTML exceeds 100,000 character limit — request rejected
- Attribute name does not match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
- No option elements found matching the given attribute/value pair — empty result set
- JavaScript-rendered content not available — static parser only, dynamic dropdowns may be missed

## How this service works

Option labels — Empty value report: Empty value report for Option labels. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded empty value report result.

## Output
