# UUID Generator API
[](https://uuid-generator.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Generate UUID v4, v7, ULID, or nanoid identifiers. Batch up to 100 at once. Sortable, compact, or random formats. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"uuid-generator": {
"url": "https://uuid-generator.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://uuid-generator.api.klymax402.com/api/generate" \
-H "Content-Type: application/json" \
-d '{}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `utility_generate_uuid` | POST | `/api/generate` | $0.003 | Generate unique identifiers |
### `utility_generate_uuid`
Use this when you need to generate unique identifiers for database records, API keys, or session tokens. Returns an array of IDs in the chosen format.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `format` | string | no | Format: uuidv4, uuidv7, ulid, nanoid (default: uuidv4) |
| `count` | number | no | Number to generate (default: 1, max: 100) |
| `length` | number | no | Length for nanoid (default: 21) |
Example response:
```json
{"ids":["550e8400-e29b-41d4-a716-446655440000"],"format":"uuidv4","count":1}
```
**When to use**: creating primary keys, correlation IDs, or unique file names. Use uuidv7 or ulid WHEN you need time-sortable IDs for databases. Use nanoid FOR short URL-safe tokens.
**Not for**: hashing (use `crypto_generate_hash`), password generation (use `security_check_password`), slug generation (use `text_generate_slug`).
