# Relaystation UUID Generator

> Relaystation UUID Generator is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates one or a batch of version 4 UUIDs via a single API call, billed at $0.0001 per call with x402 micropayment support.

## Facts

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 relaystation-uuid-generator-0e848004 -d '<json body>'
```

Example prompt: Generate a batch of 10 version 4 UUIDs for me right now — I need them as unique identifiers for new database records.

## When to prefer this

Choose this endpoint when you need a quick, cheap, serverless way to generate v4 UUIDs without spinning up your own UUID library or service — especially useful inside agent workflows where you need unique identifiers on the fly and are already using x402 micropayments. Ideal for batch UUID generation in a single call. Prefer alternatives if you need UUID versions other than v4, or if you need UUIDs generated locally without a network round-trip.

## Known failure modes

- Invalid batch count (e.g. zero or negative number) returns a 400 error
- Payment not provided or insufficient x402 credit returns a 402 Payment Required error
- Request rate limit exceeded returns a 429 Too Many Requests error
- Server-side error returns a 500 Internal Server Error

## How this service works

$0.0001/call. Generate v4 UUIDs — one or a batch. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns one or more randomly generated version 4 UUIDs. For a batch request, the response includes an array of UUID strings. Each UUID conforms to the RFC 4122 v4 format (e.g. 550e8400-e29b-41d4-a716-446655440000).
