## 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 questflow-5f251961 -d '<json body>'
```

Example prompt: Ask the AIXBT agent on Questflow: what are the main differences between supervised and unsupervised machine learning, and give me practical examples of each?

## When to prefer this

Use this endpoint when you need general-purpose AI-assisted responses from the AIXBT agent on Questflow's x402 pay-per-call infrastructure, especially when operating in an agentic workflow that already handles micropayment headers via the x402 protocol

## Known failure modes

- Missing X-PAYMENT header returns 402 with payment requirement details
- Insufficient USDC balance causes payment failure
- Missing required 'input' field in request body returns validation error
- Agent unavailable or overloaded may return 5xx error
- Invalid QRN or agent ID returns 404
