## 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 clearcheck-pii-redaction-3631fe4c
```

Example prompt: Can you redact all personal information from this text and tell me exactly what was removed: 'Please contact John Smith at john.smith@example.com or call 555-867-5309. His billing address is 123 Main St, Springfield, IL 62701.'

## When to prefer this

Choose this endpoint when you need both redaction AND an audit trail of what was removed (types and counts), not just a cleaned output. Ideal for compliance workflows, legal document processing, or any pipeline where you need to verify PII was present before sharing data downstream. The per-call pricing at $0.02 USDC suits low-to-medium volume use cases via x402 micropayments without subscription overhead.

## Known failure modes

- Text exceeds 6000 character limit — request will fail or be truncated
- No PII detected — returns original text unchanged with zero removed count
- Ambiguous names or context-dependent entities may be missed or over-redacted
- Non-English text may have reduced detection accuracy
- Service unavailable on Render free tier cold starts causing timeout

## How this service works

Strip personal information from a passage and report exactly what was removed. Names, emails, phones, cards, addresses.

## Output

Returns the original text with all detected PII replaced by placeholders, plus an array of removed item types and their counts, a total removed integer, a verdict string summarizing the outcome, the model used for detection, and a disclaimer. Allows downstream systems to verify exactly what sensitive data was present.
