## 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 ai-watermark-provenance-verifier-02286484 -d '<json body>'
```

Example prompt: Can you verify whether this piece of text has an AI watermark and tell me where it originated from? Here's the content: 'The rapid expansion of renewable energy sources has fundamentally altered global power grids...'

## When to prefer this

Use this endpoint when you need to verify whether text or AI-generated content carries an embedded watermark or provenance signature, particularly in publishing pipelines, content moderation workflows, or compliance audits where AI content authenticity must be confirmed. Prefer this over generic content classifiers when you specifically need watermark-level traceability rather than just a probability score of AI authorship.

## Known failure modes

- Empty or null data field returns a validation error
- Content too short to contain detectable watermark patterns may return inconclusive result
- Non-AI-generated content returns no watermark detected
- Malformed input string may result in a processing error
- Content in unsupported formats or encodings may fail to parse

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a provenance verification result indicating whether the submitted content contains detectable AI watermarks, along with origin attribution details, watermark status, and an authenticity confidence score if available.
