## 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 ipv4-address-redaction-in-text-6f9a9297 -d '<json body>'
```

Example prompt: Redact all IPv4 addresses from this server log text so I can share it safely: '2024-01-10 12:34:56 Connection from 192.168.1.42 to 10.0.0.1 failed, retried from 203.0.113.99.'

## When to prefer this

Choose this endpoint when you need a stateless, pay-per-call IPv4 redaction operation with no data retention, suitable for privacy-sensitive content. Prefer the free sandbox endpoint (/v1/sandbox/redact-ipv4) for development or testing. Use this paid endpoint for production workloads where you need guaranteed processing without rate limits.

## Known failure modes

- Text exceeds 100,000 character limit — request rejected with validation error
- Empty or missing text field — returns a validation error
- Malformed JSON body — HTTP 400 error
- Payment of $0.009 USDC not provided — HTTP 402 Payment Required (use unpaid sandbox endpoint /v1/sandbox/redact-ipv4 for testing)

## How this service works

Call when an agent needs ipv4 matches redacted in text. Nothing is stored. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/redact-ipv4 first.

## Output

Returns the original text with all valid IPv4 addresses replaced by a redaction placeholder (e.g. [REDACTED] or similar). No data is stored server-side after the response is returned.
