# ONE Engine IPv4 Extractor

> ONE Engine IPv4 Extractor is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Extracts IPv4 addresses from a block of text up to 50,000 characters

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-extractor-011af436 -d '<json body>'
```

Example prompt: Can you scan this server log and pull out every IPv4 address mentioned in it? Here's the text: [paste log content up to 50,000 characters]

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call extraction of IPv4 addresses from unstructured text — particularly useful in automated agent pipelines where you process many log files or documents and only want to pay per actual call at $0.0005 USDC. Prefer it over heavier NLP or regex solutions when you want a managed, reliable extraction without standing up your own infrastructure.

## Known failure modes

- Text exceeds 50,000 character limit — request will be rejected or truncated
- No IPv4 addresses found — returns empty result set
- Malformed input (non-string value) — schema validation error
- Payment failure via x402 protocol — 402 response, call not processed

## 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 submitted text, returned as a structured response with the identified addresses listed out.
