# PII Redact

> PII Redact is a paid API for AI agents from pii-redact.x402supply.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-17).

Detects and redacts personally identifiable information (PII) in text or JSON using regex and checksum-based pattern matching, with configurable mask/label/remove modes.

## 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 pii-redact-daa14f53 -d '<json body>'
```

Example prompt: Can you redact all PII from this text — mask any emails, phone numbers, SSNs, and credit card numbers: 'Contact John at john.doe@example.com or 555-123-4567, SSN 123-45-6789, card 4111111111111111'?

## When to prefer this

Choose this endpoint when you need fast, deterministic PII redaction without LLM overhead — ideal for pipelines where privacy compliance is required but you want no external AI inference, low latency, and predictable behavior. Best suited for structured data (JSON) or semi-structured text with clear PII patterns. Prefer this over LLM-based redaction when you need checksum-validated matching (e.g., Luhn for credit cards, mod-97 for IBANs) and low false-positive rates for US locale data.

## Known failure modes

- Invalid or missing 'input' field returns a validation error
- Empty 'entities' array (minItems: 1 required) causes a schema validation failure
- Unsupported locale (only 'us' is supported) returns an error
- Malformed JSON input object may cause parsing failures
- Person names or dates of birth without nearby context keywords (e.g. 'Mr.', 'DOB:') may not be detected, leading to missed PII
- High false-negative rate for NER-style names not preceded by titles or context markers
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Detect and redact PII in text or JSON. Recognizers are pure pattern/checksum matching (regex + Luhn/mod-97/SSN-area validation) — no LLM calls, no external services. Person names and dates of birth are matched only via nearby context (e.g. 'Mr. Smith', 'DOB: ...'), not general NER, to keep false positives low.

## Output

Returns the input text or JSON with PII replaced, removed, or labeled according to the chosen mode. In mask mode, PII spans are replaced with tokens like [EMAIL] or [SSN]. In label mode, the original text is annotated with entity type tags. In remove mode, PII is deleted. The response reflects the same structure as the input (string or JSON object).
