## 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-dev-hypercli-com-92a005d8 -d '<json body>'
```

Example prompt: Call the HyperCLI x402 AI agent for me — I want to send it a task and pay the $0.01 USDC fee per call using x402 on Base.

## When to prefer this

Choose this endpoint when you need to invoke the HyperCLI x402 v2 AI agent specifically and are set up to handle x402 micropayment flows using USDC on Base. Ideal for agent-to-agent workflows where per-call billing via crypto is acceptable and the x402 protocol is supported.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid x402 payment header returns authentication error
- Base network congestion causes timeout
- Malformed request payload returns 400 bad request
- Payment on wrong network (not eip155:8453) rejected

## Output

The agent receives a response from the HyperCLI x402 v2 AI agent after the USDC micropayment on Base is processed. The response contains the agent's output for the submitted request.
