Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-shield-hazel-vercel-app-d207868f -d '<json body>'
```

Example prompt: Scan this text for any sensitive information like SSNs, credit cards, crypto wallets, or API keys before I send it: 'Contact john.smith@example.com, card 5555555555554444, SSN 987-65-4321, key sk-test1234567890abcdef'

## When to prefer this

Use this endpoint when you need fast, real-time PII detection across multiple sensitive data types in a single call — especially when you need Luhn-validated credit card detection, SSN validation, and crypto address recognition together. Prefer over regex-only solutions when accuracy matters. Ideal for pre-processing user input, log scrubbing, or compliance checks before storing or forwarding data.

## Known failure modes

- Empty or missing text field returns no findings or validation error
- Very long text may exceed processing limits
- Obfuscated or encoded PII (base64, hex) may not be detected
- Partial or malformed SSNs may not pass Luhn/validation checks
- Rate limiting or payment failure at $0.02 USDC per call via x402 protocol

## Output

Returns a JSON object with a list of findings, each containing the PII type, a redacted match, character position, and sensitivity level (high/critical). Also includes a top-level sensitivity rating, pii_detected boolean, total findings count, text length, and analysis timestamp.

## Example request
