## 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 payai-pii-scanner-320dc865 -d '<json body>'
```

Example prompt: Can you scan this text for any PII — emails, phone numbers, credit card numbers, crypto addresses, tax IDs, or secrets — and give me a breakdown of what was found with confidence scores? Here's the text: 'Contact John at john.doe@example.com or call 415-555-0192. His SSN is 123-45-6789.'

## When to prefer this

Choose this endpoint when you need structured, categorized PII detection with confidence scores across a broad range of PII types (including crypto addresses, MAC addresses, geo coordinates, and secrets) in a single call. Prefer it over regex-only approaches or general-purpose LLM extraction when you need machine-readable, typed findings with compliance summaries for downstream automation or audit trails.

## Known failure modes

- Empty or missing text body returns no findings rather than an error
- Very long text blobs may hit payload size limits
- Low-confidence matches may produce false positives for ambiguous patterns like short numeric strings
- Secrets and API keys are heuristic-based and may miss novel formats
- No legal or regulatory advice is provided — compliance summary is informational only

## How this service works

Detect structured PII in a text blob: emails, phones, credit cards, bank and tax ids, IP and MAC addresses, crypto addresses, dates of birth, geo coordinates and secrets. Returns findings with a confidence score plus a compliance summary. No transformed text. Structured PII indicators, not legal advice.

## Output

Returns a structured list of PII findings, each with the matched value, category (e.g. email, credit card, crypto address), character offset or location, and a confidence score. Also includes a compliance summary indicating which PII types were detected overall. No redacted or transformed text is returned.
