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-from-text-03261cd2 -d '<json body>'
```

Example prompt: Can you extract all the IPv4 addresses from this server log text? Here it is: '2024-01-15 10:23:01 Connection from 192.168.1.45 to 10.0.0.1 failed; retry from 172.16.254.3 at 10:23:05'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call solution to extract IPv4 addresses from arbitrary text without standing up your own regex pipeline or NLP service. Ideal for agents processing logs, config files, threat reports, or any unstructured document where IPv4 addresses need to be identified programmatically. Best suited for one-off or infrequent extractions given the per-call cost model on Base via x402.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No IPv4 addresses present in text — empty result returned
- Payment failure via x402 — 402 Payment Required error
- Malformed input JSON missing required 'text' field — 400 error
- Text contains only IPv6 or non-IP network addresses — may return empty or partial results

## How this service works

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

## Output

A JSON object containing the extracted IPv4 addresses found in the submitted text, returned as structured data for further processing or analysis.
