## 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-url-namespace-generator-2d15e3bd -d '<json body>'
```

Example prompt: Generate a deterministic UUID v5 in the URL namespace for the text 'https://example.com/product/42'.

## When to prefer this

Choose this endpoint when you need a paid, production-grade UUID v5 in the URL namespace and the free sandbox endpoint (POST /v1/sandbox/uuid-name-v5-url) is unavailable or unsuitable. Prefer this when operating in a live agent pipeline where reliability and SLA matter more than cost savings.

## Known failure modes

- Empty or missing text field returns a validation error
- Input text exceeding 100,000 characters is rejected
- Payment of $0.002 USDC not provided results in 402 Payment Required
- Network or service unavailability returns 5xx error

## How this service works

Call when an agent needs a deterministic UUID v5 in the url namespace. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/uuid-name-v5-url first.

## Output

Returns a deterministic UUID v5 string computed by hashing the input text in the URL namespace (RFC 4122). The same input always produces the same UUID output, making it suitable for idempotency keys, cache keys, and deduplication identifiers.
