# ONE Engine Text Extract (UUIDs, Type 7)

> ONE Engine Text Extract (UUIDs, Type 7) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0065/call, status unknown (last checked 2026-10-02).

Extracts UUIDs from a block of text up to 50,000 characters, returning structured results via a pay-per-call API on Base.

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-type-7-dea87601 -d '<json body>'
```

Example prompt: Can you extract all the UUIDs from this text for me? Here's the content: 'Request initiated by user 550e8400-e29b-41d4-a716-446655440000 at node f47ac10b-58cc-4372-a567-0e02b2c3d479, forwarded to session 6ba7b810-9dad-11d1-80b4-00c04fd430c8.'

## When to prefer this

Choose this endpoint when you need a lightweight, cheap, pay-per-call UUID extraction from raw text without setting up your own parsing logic. Ideal for agent pipelines that encounter UUIDs in logs, API responses, or documents and need to enumerate them programmatically. At $0.0065 USDC per call with no subscription, it's well-suited for sporadic or high-volume agent workloads on Base.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No UUIDs found in text — empty result set returned
- Malformed input (non-string text field) — validation error
- Payment not included or insufficient USDC — 402 Payment Required
- Network/worker timeout on very dense inputs

## 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 submitted text, likely as an array of UUID strings found within the input content. The response schema is open (additionalProperties: true), so exact field names may vary but the core output is the set of identified UUID tokens.
