## 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-v4-generator-api-52ef89b5 -d '<json body>'
```

Example prompt: Generate a fresh cryptographically random UUID v4 I can use as a unique job ID for my pipeline run.

## When to prefer this

Choose this endpoint when your AI agent needs a server-generated, cryptographically random UUID v4 that doesn't rely on local library availability — especially useful in sandboxed agent environments, for auditability of ID generation, or when you want a paid, accountable source for unique identifiers. Prefer this over local UUID libraries when running in restricted runtimes or when you need guaranteed v4 randomness without trusting local entropy.

## Known failure modes

- Payment failure: insufficient USDC balance on Base returns 402 Payment Required
- Network timeout: endpoint unreachable returns connection error
- Invalid request format: missing required 'input' object returns 400 Bad Request
- Rate limiting: too many rapid calls may return 429 Too Many Requests

## How this service works

UUID v4 generator API for AI agents — cryptographically random UUID per call, $0.001 USDC on Base. IDs for jobs, dedup keys, request tracing.

## Output

Returns a single cryptographically random UUID v4 string (e.g. '550e8400-e29b-41d4-a716-446655440000') suitable for use as a unique identifier in job queues, deduplication, database keys, or distributed tracing.
