# ONE Engine Text Extract UUIDs

> ONE Engine Text Extract UUIDs is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-02).

Extracts UUID v4 identifiers found within 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-text-extract-uuids-719a34ac -d '<json body>'
```

Example prompt: Can you scan this log output and pull out every UUID v4 that appears in it? Here's the text: 'Processing request 550e8400-e29b-41d4-a716-446655440000 for user 6ba7b810-9dad-11d1-80b4-00c04fd430c8 at 2024-01-15T10:30:00Z.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call service to programmatically extract UUID v4 identifiers from arbitrary text blobs, log output, or configuration data without standing up your own parsing infrastructure. Particularly suited for autonomous agents operating on Base with x402 micropayment support at $0.0015 per call.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No UUIDs found in text — empty result returned
- Malformed request body (missing 'text' field) — validation error
- Payment failure via x402 — 402 response before processing begins

## How this service works

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

## Output

A JSON object containing the UUIDs extracted from the provided text, returned as a list or structured map of UUID v4 strings found within the input.
