# Tanod utilpeek UUID/ULID Generator

> Tanod utilpeek UUID/ULID Generator is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Generates one or more UUID v4, UUID v7, or ULID identifiers with optional monotonic ordering

## Facts

- Endpoint: GET https://tanod.dev/v1/uuid?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/tanod-utilpeek-uuid-ulid-generator-fe21c83a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_1xYe38qGsFFa1VT8b_dEH

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 tanod-utilpeek-uuid-ulid-generator-fe21c83a
```

Example prompt: Generate 5 time-ordered UUID v7 identifiers for me, all strictly monotonically increasing.

## When to prefer this

Choose this endpoint when you need server-side generation of cryptographically sound UUID v4, time-ordered UUID v7, or ULID identifiers without setting up local libraries — especially useful in agent workflows that require unique IDs on demand, need batches of up to 100 at a time, or require strictly monotonic ordering guarantees within a single response.

## Known failure modes

- count out of range (must be 1-100): validation error returned
- invalid kind value (not 'uuid' or 'ulid'): schema validation error
- version not 4 or 7: schema validation error
- monotonic flag used with UUID v4 (only valid for v7/ULID): may return error or be ignored
- payment failure via x402 protocol: 402 response requiring USDC payment

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

An array of one or more generated identifier strings (UUIDs or ULIDs) matching the requested kind, version, count, and monotonicity settings.
