## 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-analyzer-d4929daf -d '<json body>'
```

Example prompt: Can you check if this DeFi transaction looks fraudulent? Here's the description: 'Unknown contract requesting unlimited token approval from my wallet, promising 900% APY on a newly launched token with anonymous team.'

## When to prefer this

Choose this endpoint when you need a fast, single boolean fraud signal on a DeFi-related text description or transaction scenario, especially in agentic pipelines where a lightweight true/false gate is sufficient before taking action. It is best suited for pre-screening DeFi interactions, flagging suspicious prompts, or building fraud-check steps into automated crypto workflows. Prefer alternatives if you need a granular confidence score, detailed reasoning, or multi-label fraud categorization.

## Known failure modes

- Missing required 'prompt' field returns a 400/422 validation error
- Ambiguous or very short prompts may yield unreliable boolean results with no confidence detail
- Payment failure via x402 protocol results in 402 Payment Required before execution
- Overly long prompts may be truncated or rejected
- Network latency on Base L2 settlement may occasionally delay response

## How this service works

## Output

Returns a JSON object with a single boolean field 'score' — true indicates the analyzed prompt/transaction description is flagged as fraudulent or suspicious, false indicates it appears clean.
