## 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 synthex-forge-pii-redaction-d79d4349 -d '<json body>'
```

Example prompt: Can you redact all PII — including names — from this text: 'John Smith called us from 555-867-5309 and his email is john.smith@example.com. He lives at 42 Maple Street, Boston.'

## When to prefer this

Choose this endpoint when you need a paid, attestation-backed PII redaction with cryptographic proof of result (Ed25519 + SHA-256 signed artifacts), particularly in compliance-sensitive or audit-trail workflows. Prefer it over general-purpose NLP APIs when you need verifiable, governance-grade anonymization and are operating in a USDC micropayment context via x402.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Malformed JSON body causes a 400 Bad Request
- Payment not included or insufficient triggers HTTP 402 with an x402 v2 payment-required envelope requiring USDC on Base mainnet (chain ID 8453)
- Oversized text payload may result in a timeout or payload-too-large error
- Network or service unavailability returns 5xx errors

## How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

## Output

Returns a JSON object with an 'ok' boolean and the sanitized text with PII (and optionally names) replaced or removed. The response is signed using Ed25519 + SHA-256 as part of the Synthex Forge attestation framework.
