```sh
zero fetch --capability whatchuneed-tempest-transpose-57b9af6b -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call data transposition or transformation step accessible via a single unified gateway, especially in agentic workflows where you want to avoid managing multiple service accounts and prefer USDC micropayment billing.

## Known failure modes

- Missing required 'input' field returns validation error

- Service unavailability on vercel.app infrastructure causes timeout or 5xx
- Payment failure via x402 protocol results in 402 response before processing
- Ambiguous input string may return unexpected or unstructured result object
