## 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 openverbs-pii-redaction-a5ccf24c -d '<json body>'
```

Example prompt: Redact all PII from this text using hash mode so equal values stay linkable: 'Contact John at john@example.com or call 555-123-4567, card ending 4111-1111-1111-1111.'

## When to prefer this

Choose this endpoint when you need fully offline, privacy-preserving PII redaction with flexible replacement styles — especially when you want stable hash fingerprints to keep linkability without exposing raw values. Prefer it over cloud-based PII APIs when data must not leave local processing, or when you need per-type filtering (e.g. only redact credit cards and SSNs). The hash mode is particularly useful for analytics pipelines where you need to join anonymized records.

## Known failure modes

- Missing required 'text' field returns validation error
- Text exceeding 200,000 characters is rejected
- Invalid 'mode' value outside enum returns 400
- Invalid PII type in 'types' array returns schema validation error
- Empty mask character or mask longer than 8 characters rejected
- Payment not provided or insufficient USDC balance results in 402 response

## How this service works

Return the input text with every detected PII span replaced. `mode` controls the replacement: "label" (default) → `[EMAIL]`; "mask" → the value covered with a mask character; "hash" → `[EMAIL:1a2b3c4d]`, a stable per-value fingerprint so equal values stay linkable without exposing them. Same validated detectors as `/detect`. Fully offline.

## Output

Returns the original text with every detected PII span replaced according to the chosen mode: 'label' wraps type names in brackets (e.g. [EMAIL]), 'mask' covers characters with the specified mask character (default •), and 'hash' produces a stable bracketed fingerprint (e.g. [EMAIL:1a2b3c4d]) that remains consistent across identical values for linkability.
