Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentshelf-syntexa-ch-email-redaction-d6503cc3 -d '<json body>'
```

Example prompt: Redact all email addresses from this text before I share it: 'Please contact John at john.doe@example.com or reach support at help@company.org for assistance.'

## When to prefer this

Use this endpoint when you need a simple, stateless, pay-per-call email redaction with no data retention guarantees. It is ideal for privacy-sensitive pipelines where you cannot risk storing PII on a third-party server. Prefer the free sandbox endpoint (POST /v1/sandbox/redact-email) for testing or non-production use before paying. Choose this over regex-only approaches when you want a maintained, API-grade solution that handles edge cases in email pattern matching.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected with validation error
- Empty or missing text field — returns a 400 bad request
- Malformed JSON body — parse error response
- Payment of $0.007 USDC not provided or failed — 402 Payment Required
- Network timeout on very large texts near the character limit

## How this service works

Call when an agent needs email matches redacted in text. Nothing is stored. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/redact-email first.

## Output

The endpoint returns the input text with all email address patterns replaced by redacted placeholders (e.g. [REDACTED] or similar masking), leaving all other content intact. No data is stored server-side.
