## 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-v5-dns-namespace-generator-a7d64249 -d '<json body>'
```

Example prompt: Generate a deterministic UUID v5 in the DNS namespace for the text 'api.example.com' — I need the same UUID every time for this name.

## When to prefer this

Use this endpoint when you need a deterministic, standards-compliant UUID v5 in the DNS namespace and want a guaranteed computation without relying on a local library or LLM. Prefer the free sandbox POST /v1/sandbox/uuid-name-v5-dns first; use this paid endpoint when the sandbox is unavailable or when operating in a production context that requires the paid tier.

## Known failure modes

- Empty or missing text input returns a validation error
- Text exceeding 100,000 characters is rejected
- Network or service unavailability returns a 5xx error
- Invalid payment or insufficient USDC balance returns a 402 error

## How this service works

Call when an agent needs a deterministic UUID v5 in the dns namespace. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/uuid-name-v5-dns first.

## Output

A deterministic UUID v5 string derived from the DNS namespace (6ba7b810-9dad-11d1-80b4-00c04fd430c8) and the provided text input. The same input always produces the same UUID output.
