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 one-engine-ipv4-address-extractor-c1f3094e -d '<json body>'
```

Example prompt: Can you pull out all the IPv4 addresses from this server log text for me? Here's the content: 'Connection from 192.168.1.45 refused; retry from 10.0.0.1 succeeded at 172.16.254.3.'

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call IPv4 address extraction from unstructured text without standing up your own NLP pipeline. Ideal for agents processing logs, reports, or config files on an ad-hoc basis where cost-per-call pricing ($0.0025 USDC) is preferable to a subscription. Best for text-based inputs up to 50,000 characters where the goal is purely identifying and listing IPv4 addresses.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- No IPv4 addresses present in text — returns empty result
- Malformed or ambiguous IP-like strings may be misidentified or omitted
- Payment failure via x402 protocol results in 402 response before processing
- Model may miss IPv4 addresses embedded in unusual formatting

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the IPv4 addresses extracted from the input text, identified by a T5-based extraction model. The response may include an array or list of matched IPv4 address strings found within the provided content.
