## 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 nova-ai-inference-api-4a3edff6 -d '<json body>'
```

Example prompt: Ask Nova to summarize the pros and cons of electric vehicles for a general audience — I want a clear, balanced answer I can share in a newsletter.

## When to prefer this

Choose this endpoint when you need on-demand AI inference (chat, reasoning, translation, analysis, or generation) paid per-call in USDC on Base, especially in agentic or crypto-native workflows where you want pay-as-you-go without a subscription.

## Known failure modes

- Missing required 'query' field returns a validation error
- Payment failure or insufficient USDC balance results in a 402 payment required response
- Empty or ambiguous query may return a low-quality or generic answer
- Model unavailability may return a 503 or error in the response body
- Network timeout if inference takes too long
