## 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 nlp-fraud-detection-auditor-mcp-93a11d70 -d '<json body>'
```

Example prompt: Can you run a fraud detection check on this transaction hash 0xabc123def456... and tell me if it's flagged as fraudulent?

## When to prefer this

Use this endpoint when you need a fast, automated NLP-based fraud verdict on a specific transaction hash, especially in blockchain or crypto-payment contexts where you want a binary fraudulent/legitimate signal without building your own model. It is best suited for per-transaction screening pipelines that can tolerate a per-call USDC micropayment via x402 protocol.

## Known failure modes

- Missing required 'hash' field returns a 400 or validation error
- Invalid or malformed hash string may return an error or unpredictable prediction
- Payment failure (insufficient USDC balance) results in 402 Payment Required response
- Network or node unavailability returns a 5xx error
- Hash not found in underlying model's dataset may yield low-confidence or default prediction

## 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 field 'prediction': true indicates the transaction hash is classified as fraudulent, false indicates it is considered legitimate.
