## 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 signaldesk-ai-ipv4-validate-f9a4c91a -d '<json body>'
```

Example prompt: Can you check if '203.0.113.42' is a valid IPv4 address before I use it in my network config?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001 USDC), server-side IPv4 format check without implementing regex locally. Useful in agent pipelines that handle user-supplied IP strings and need to guard against malformed inputs before passing them to downstream network or geolocation APIs.

## Known failure modes

- Missing or empty 'ip' field in request body returns an error or false result
- String exceeding 64 characters may be rejected
- Non-string types for 'ip' field may cause a parsing error
- Network timeout or worker unavailability returns a 5xx error
- Malformed JSON body returns a 400-level error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with a single boolean field 'valid' indicating whether the provided string is a correctly formatted IPv4 address (true) or not (false).
