## 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-search-query-endpoint-c1b5907c -d '<json body>'
```

Example prompt: Ask Nova to explain the difference between proof-of-work and proof-of-stake in plain English — just send the query and get back its AI-generated answer.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call AI inference call billed in USDC on Base without a subscription or API key commitment — ideal for crypto-native agents that can execute x402 micropayments and need one-shot question answering, reasoning, or text generation at $0.05 per call.

## Known failure modes

- Payment not made or insufficient USDC balance — returns 402 Payment Required
- Missing required `query` field — likely 400 Bad Request
- Invalid or malformed JSON body — 400 Bad Request
- Upstream model unavailable — possible 503 or timeout
- Query too long or exceeds token limits — potential error response
