## 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-classifier-19ebfff0 -d '<json body>'
```

Example prompt: Can you run fraud detection on this DeFi transaction — the hash is 0x4f3a9b2e1c8d7f6a0b5e2c1d9a8f7b6e3c2d1a0f4b5e6c7d8a9b0c1d2e3f4a5b?

## When to prefer this

Choose this endpoint when you need a fast, automated boolean fraud signal on a specific DeFi transaction hash without building your own on-chain analytics pipeline. Useful for pre-settlement checks, compliance screening, or alert systems where a simple true/false fraud flag is sufficient and sub-second latency matters.

## Known failure modes

- Missing or malformed transaction hash returns a validation error
- Hash does not exist on-chain may yield an inconclusive or default false result
- Insufficient payment (x402 payment not included) results in a 402 Payment Required response
- Rate limiting or node unavailability may cause timeouts or 503 errors
- Novel or unseen fraud patterns may result in false negatives (summary: false) despite actual fraud

## 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

A JSON object with a boolean 'summary' field — true if the transaction is classified as fraudulent, false if it appears legitimate.
