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-value-report-d73c57bb -d '<json body>'
```

Example prompt: Scan this HTML page for duplicate `id` attribute values across all code snippet elements — here's the HTML: `<!doctype html><html><body><code id="sample">A</code><code id="sample">B</code></body></html>` — and tell me which values appear more than once.

## When to prefer this

Choose this endpoint when you need to detect duplicate attribute values specifically within code snippet elements on a static HTML page, without JavaScript rendering. It is ideal for documentation quality checks, pre-publish HTML validation, or auditing code block uniqueness constraints. Prefer this over general duplicate-detection tools when the scope is limited to code elements and a specific HTML attribute.

## Known failure modes

- URL is unreachable or returns a non-200 status — report will be empty or error returned
- Provided HTML exceeds 100,000 character limit — request rejected
- JavaScript-rendered content not parsed — dynamic code snippets may be missed
- No code snippet elements found matching the term — empty report returned
- Attribute name does not match pattern requirements — validation error returned
- previous_texts list exceeds 200 items — request rejected

## How this service works

Code snippets — Duplicate value report: Duplicate value report 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 value report result.

## Output

A bounded duplicate value report identifying which attribute values appear more than once across code snippet elements on the scanned page or HTML, along with occurrence details for each duplicate found.
