## 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 arch-tools-pii-detect-89fb6922 -d '<json body>'
```

Example prompt: Scan this text for any PII and give me back a redacted version: 'Hi, my name is John Smith, my email is john@example.com and my SSN is 123-45-6789.'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call PII scan without standing up your own NLP pipeline or managing a subscription. It is ideal for agents processing user-generated content, logs, or documents that must be checked for privacy compliance before storage or sharing. Prefer it over general entity extraction endpoints when your primary goal is privacy-focused PII identification and optional redaction rather than broad NER.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Very long text inputs may hit size limits or time out
- False negatives: uncommon or obfuscated PII formats may not be detected
- False positives: non-PII strings resembling PII patterns may be flagged
- Non-English text may have reduced detection accuracy
- Payment failure via x402 protocol returns 402 before processing
