## 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-monitor-874f0435 -d '<json body>'
```

Example prompt: Can you check if this DeFi contract address 0xAbCd...1234 shows any signs of fraud or rug pull behavior?

## When to prefer this

Use this endpoint when you need a fast, low-cost boolean fraud signal for DeFi-related queries such as contract addresses, wallet addresses, or protocol names. It is best suited for quick go/no-go screening rather than deep forensic analysis. Prefer this over general blockchain analytics APIs when you need a lightweight, pay-per-call fraud flag without managing complex data pipelines.

## Known failure modes

- Missing required `query` field returns a 400 or schema validation error
- Empty or malformed query string may return an ambiguous result
- Payment failure (insufficient USDC) returns HTTP 402 and blocks execution
- Very short or uninformative queries may produce unreliable boolean results
- Network or node unavailability may return a 503 or timeout

## 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 single boolean `score` field: `true` indicates detected fraud or high suspicion, `false` indicates no fraud detected for the given query.
