# ONE Engine IPv4 Address Extractor from Text

> ONE Engine IPv4 Address Extractor from Text is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-02).

Extracts IPv4 addresses from a block of text (up to 50,000 characters) using a pay-per-call API on Base via x402.

## 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-faa9edc1 -d '<json body>'
```

Example prompt: Can you extract all the IPv4 addresses from this server log text for me? Here's the content: [paste log text 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 (logs, configs, documents) without setting up a full NLP pipeline. Ideal for autonomous agents that process text in one-off tasks and want to pay only for what they use via x402 on Base.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No IPv4 addresses found in text — returns empty result
- Payment failure via x402/Base — 402 response requiring valid USDC payment
- Malformed input JSON missing required 'text' field — 400 error
- Network timeout on Cloudflare Worker — intermittent 503

## 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, likely as an array or structured list of matched address strings found within the input.
