# 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, $0.01/call, status unknown (last checked 2026-10-02).

Extracts UUIDs from a block of text using a pay-per-call utility API on Base via x402.

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-bb1939fc -d '<json body>'
```

Example prompt: Can you extract all the UUIDs from this text for me? Here it is: 'User session abc123 maps to id 550e8400-e29b-41d4-a716-446655440000 and was linked to order 6ba7b810-9dad-11d1-80b4-00c04fd430c8 in our system.'

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) programmatic way to extract UUID identifiers from arbitrary text without running a regex locally. Ideal for AI agents operating autonomously on Base that need to parse identifiers out of logs, API responses, or documents as a single step in a workflow, especially when integrated with x402 micropayment flows.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- No UUIDs found in text — may return empty result
- Malformed or missing 'text' field — validation error
- Payment failure via x402 — 402 response before processing
- Ambiguous UUID-like strings (e.g. partial matches) may or may not be included

## 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 UUIDs extracted from the provided text, likely as an array or structured map of UUID strings found within the input.
