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 uuid-generator-api-klymax402-com-6602021f
```

Example prompt: Generate 5 unique identifiers in UUIDv4 format for me.

## When to prefer this

Use this endpoint when your agent needs fresh, cryptographically random or time-ordered unique identifiers on demand without running local code. Particularly useful for generating UUIDv7 (time-sortable) or ULID identifiers that are not always available in standard libraries, or when you need a batch of up to 100 IDs in one call.

## Known failure modes

- count exceeds maximum of 100 — returns error
- invalid format value — returns error for unrecognized format string
- invalid length for NanoID — returns error if length is out of range
- payment failure — x402 payment required before IDs are returned

## How this service works

Generate unique identifiers

## Output

Returns one or more unique identifiers in the requested format (UUIDv4, UUIDv7, ULID, or NanoID). The response contains the generated IDs, count, and format used. NanoID supports a configurable length parameter.
