## 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 m2mcent-defi-fraud-detection-aggregator-mcp-600a3a62 -d '<json body>'
```

Example prompt: Check this DeFi wallet address 0x1234abcd... for fraud signals — I want to know if it's been flagged by the aggregated fraud detection system before I interact with it.

## When to prefer this

Choose this endpoint when you need a fast, aggregated DeFi fraud detection signal via a pay-per-call x402 micropayment model on Base L2, especially when you want to avoid building your own fraud aggregation layer. Best suited for lightweight go/no-go fraud screening where a boolean signal is sufficient and cost-per-call economics fit the use case.

## Known failure modes

- Missing or malformed payload string returns 400 validation error
- Payment failure via x402 protocol results in 402 Payment Required
- Downstream MCP node unavailability may return 503 or timeout
- Ambiguous payload format may return a default false negative without error
- Boolean-only response provides no explanatory detail on fraud type or severity

## 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 JSON object with a 'hash' field containing a boolean value indicating whether the submitted payload triggered a fraud detection signal — true likely indicates a fraud flag, false indicates clean.
