## 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 api-barvis-io-dfc6944e -d '<json body>'
```

Example prompt: Chat with the Barvis agent and ask it: 'What are the current best practices for securing a Node.js API?' — I need a detailed, actionable answer.

## When to prefer this

Use this endpoint when you need to send a natural language message to the Barvis AI agent and receive a generated response, especially in x402 pay-per-call workflows where a $1 USDC microtransaction is acceptable per interaction.

## Known failure modes

- Invalid or missing message body returns an error
- Payment not included or insufficient USDC results in 402 payment required
- Malformed request body causes a 400 error
- Agent backend unavailable returns 503 or timeout
- Response schema may vary if agent produces unexpected output

## Output
