## 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 defi-fraud-detection-auditor-mcp-4b0a005a -d '<json body>'
```

Example prompt: Can you check if transaction hash 0xabc123...def456 is linked to any DeFi fraud or malicious activity?

## When to prefer this

Use this endpoint when you need a fast, low-cost boolean fraud verdict for a specific DeFi transaction hash, especially in automated screening pipelines where token context savings matter. Prefer it over heavier on-chain analytics tools when a simple pass/fail signal is sufficient.

## Known failure modes

- Missing or malformed transaction hash returns a validation error
- Unknown or unindexed hash may return false negatives if not in the fraud database
- Network or payment failure via x402 protocol results in no response
- Hash of a non-DeFi transaction may yield unreliable results

## How this service works

## Output

Returns a JSON object with a single boolean field 'result': true if the transaction hash is associated with DeFi fraud or malicious activity, false if it appears clean.
