## 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-nlp-fraud-detection-indexer-mcp-b048e565 -d '<json body>'
```

Example prompt: Run NLP fraud detection on this dataset: 'User submitted payment info with mismatched billing address, unusual velocity, and synthetic identity signals — transaction ID TX-9921.'

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call NLP fraud detection signal on a text or structured dataset, especially in automated pipelines where a simple boolean verdict is sufficient and you want to avoid building or hosting a fraud model yourself.

## Known failure modes

- Missing 'dataset' field returns a validation error
- Empty string dataset may return false negatives or schema errors
- Oversized dataset string may cause timeout or truncation
- Malformed JSON input returns a 400-level error
- Service unavailability returns a 402 or 5xx error if payment or upstream node fails

## 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 'summary' field indicating whether fraud was detected in the submitted dataset (true = fraud detected, false = no fraud detected).
