# UUID Generator (v4 / v7, up to 100 per batch)

> UUID Generator (v4 / v7, up to 100 per batch) is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates random v4 UUIDs or time-ordered v7 UUIDs (sortable, ULID-style) in batches of up to 100 per call.

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-v4-v7-up-to-100-per-batch-9f1ccf40
```

Example prompt: Can you generate 10 time-ordered v7 UUIDs I can use as sortable primary keys for my database inserts?

## When to prefer this

Choose this endpoint when you need to generate multiple UUIDs in a single call (up to 100), especially when sortable v7 UUIDs are required for database primary keys or distributed system identifiers. Prefer v7 when lexicographic ordering or time-ordering matters; prefer v4 for purely random, opaque identifiers.

## Known failure modes

- Invalid version parameter (not v4 or v7) returns an error
- Requesting more than 100 UUIDs per batch may be rejected or capped
- Missing required query parameters returns a 400-level error
- Payment not fulfilled (x402) results in a 402 response blocking the call

## How this service works

UUID generator: random v4 UUIDs or time-ordered v7 UUIDs (sortable, great for database keys), up to 100 per call, plus a ULID-style timestamp note for v7. $0.01 per batch.

## Output

Returns an array of UUID strings (up to 100) of the requested version (v4 random or v7 time-ordered). For v7 UUIDs, a ULID-style timestamp note is included, making them lexicographically sortable and suitable for database primary keys.
