## 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-09bc61d4 -d '<json body>'
```

Example prompt: Use Nova's pay-per-call inference to translate this text to French and return the result as plain text: 'The quarterly earnings exceeded analyst expectations by a wide margin.'

## When to prefer this

Choose this endpoint when you need one-off or low-volume AI inference (chat, reasoning, translation, analysis, generation) and want to pay per call in USDC on Base without committing to a subscription. Particularly useful for agents that need occasional AI capability without managing API keys or monthly billing.

## Known failure modes

- Insufficient USDC balance causing x402 payment failure
- Missing required `prompt` field returns validation error
- Malformed `schema` object causing JSON output generation to fail
- Provider unavailability causing inference timeout
- Invalid `format` value resulting in unexpected output structure
