Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 code-snippets-duplicate-attribute-values-finder-25c170d3 -d '<json body>'
```

Example prompt: Check this HTML page at https://docs.example.com/api-reference for any duplicate 'id' attribute values among code snippet elements where the value is 'sample' — I want to know if that attribute is reused in multiple places.

## When to prefer this

Choose this endpoint when you need to statically audit HTML — either from a live public URL or a supplied HTML string — for duplicate attribute values specifically within code snippet elements. It is well-suited for documentation QA, pre-publish HTML validation, and accessibility or uniqueness audits on code blocks. Prefer it over generic HTML scrapers when you need a focused, preset-driven analysis of attribute duplication patterns without JavaScript execution overhead.

## Known failure modes

- URL unreachable or returns non-200 status — parsing cannot proceed
- HTML payload exceeds 100,000 character limit — request rejected
- Attribute name does not match required pattern (must start with letter, alphanumeric/colon/underscore/hyphen) — validation error
- No code snippet elements found in the provided HTML — empty result
- URL requires JavaScript rendering or login — content not accessible via static parse
- Term or attribute_value not found in any code elements — empty duplicate set returned

## How this service works

Code snippets — Duplicate attribute values: Duplicate attribute values for Code snippets. 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 duplicate attribute values result.

## Output

Returns a bounded result indicating which code snippet elements contain duplicate values for the specified attribute, including the matching attribute value and any occurrences found across the parsed HTML — based on static parsing with no JavaScript rendering.
