# ONE Engine IPv4 Extractor (Text)

> ONE Engine IPv4 Extractor (Text) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

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

## 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-text-b65fc116 -d '<json body>'
```

Example prompt: Can you extract all the IPv4 addresses from this server log text? Here's the log: '2024-01-15 10:23:44 Connection from 192.168.1.105 to 10.0.0.1 failed; retry from 172.16.254.3 at 10:23:50.'

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call IPv4 extraction from unstructured text without managing your own regex or NLP pipeline. At $0.001 USDC per call it is cost-effective for high-volume agent workflows processing logs, configs, or documents where IP addresses need to be identified programmatically. Best suited for autonomous agent pipelines that need lightweight, on-demand text parsing without standing up dedicated infrastructure.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No IPv4 addresses found in text — may return empty result
- Malformed JSON input — 400 error
- Payment failure via x402 — 402 response, call not processed
- Rate limiting or service unavailability — 5xx error

## How this service works

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

## Output

Returns a JSON object containing the IPv4 addresses extracted from the submitted text. The response includes the identified IP addresses parsed out from the input, though the exact response structure may vary.
