# UUID / ULID / NanoID Generator API

> UUID / ULID / NanoID Generator API is a paid API for AI agents from klymax402.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Generates one or more unique identifiers in various formats including UUIDv4, UUIDv7, ULID, and NanoID

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-ulid-nanoid-generator-api-c41dec21
```

Example prompt: Generate 10 unique identifiers for me in UUIDv4 format.

## When to prefer this

Use this endpoint when your agent needs one or more unique identifiers on demand without maintaining local state or a UUID library. Especially useful in serverless or constrained agent environments that lack native UUID generation, or when you need less common formats like ULID or NanoID alongside standard UUIDs in a single API.

## Known failure modes

- count exceeds max of 100 — returns error or truncated results
- invalid format string provided — may return error or fall back to default
- length out of valid range for nanoid — may return error
- payment not processed — HTTP 402 returned, no IDs generated

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object with an array of generated IDs ('ids'), the count of IDs generated, the format used (uuidv4, uuidv7, ulid, or nanoid), and the length (relevant for nanoid). Example: {"ids": ["..."], "count": 1, "format": "uuidv4", "length": 21}.
