# x402 Utils – Random ID Generator

> x402 Utils – Random ID Generator is a paid API for AI agents from utils.kagurazaka.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Generates cryptographically random IDs in UUID v4, UUID v7 (time-ordered), ULID, or nanoid format, returning up to 100 at a time.

## Facts

- Endpoint: GET https://utils.kagurazaka.dev/v1/id?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-utils-random-id-generator-238f4e53
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_0hzZ3m1cjI3ZPH2b4ETfk

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 x402-utils-random-id-generator-238f4e53
```

Example prompt: Generate 10 time-ordered UUID v7s so I can use them as database primary keys for new records I'm about to insert.

## When to prefer this

Use this endpoint when you need cryptographically secure random IDs in a standard format (UUID4, UUID7, ULID, or nanoid) and want to generate up to 100 at a time in a single call without running local code. Prefer UUID v7 or ULID when time-ordering matters for database indexing; prefer nanoid for short, URL-safe identifiers.

## Known failure modes

- Invalid 'type' value (not one of uuid4, uuid7, ulid, nanoid) returns an error
- count outside 1–100 range returns a validation error
- Missing required parameters may return a 400-level error
- Payment failure (x402 protocol) blocks the request

## How this service works

Generate random IDs from a cryptographic source: UUID v4, UUID v7 (time ordered), ULID or nanoid, up to 100 at a time.

## Output

A JSON object containing a 'type' field (the ID format used) and an 'ids' array with 1–100 randomly generated identifiers of the requested format.
