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-t1-4c983d7e -d '<json body>'
```

Example prompt: Can you extract all the UUIDs from this text for me? Here's the content: 'Job 3f6c1a2b-4d5e-6789-abcd-ef0123456789 was linked to session 00112233-4455-6677-8899-aabbccddeeff and asset 550e8400-e29b-41d4-a716-446655440000.'

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.0005 USDC), pay-per-call extraction of UUID/GUID identifiers from arbitrary text up to 50,000 characters, especially in agentic workflows on Base where x402 micropayments are already integrated. Prefer this over regex-based local extraction when you want a reliable hosted service without maintaining your own parsing logic.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No UUIDs present in the input text — empty or null result set returned
- Malformed or missing 'text' field in request body — validation error
- Payment failure via x402 — 402 response before processing begins
- Partial UUID strings not meeting full format may be omitted

## 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 found within the provided text, parsed and listed for programmatic use. The exact response structure may include arrays of matched UUID strings identified by the extraction algorithm.
