## 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-4613dbd0 -d '<json body>'
```

Example prompt: Purchase a basic HyperCLI access bundle for agent x402 — I want to get an API key using the x402 payment flow so my agent can start making calls right away.

## When to prefer this

Use this endpoint when an AI agent needs to autonomously purchase short-duration API access using on-chain USDC micropayments via the x402 protocol on Base, specifically for the 'basic' plan tier. Prefer this over traditional API key provisioning when the agent operates in a pay-per-use, trustless crypto-native environment and needs credentials that self-expire.

## Known failure modes

- Insufficient USDC balance — payment rejected by x402 facilitator
- Invalid or unrecognized agent_id — may return error or unexpected plan
- Network/Base chain congestion causing payment confirmation delays
- Expired or invalid x402 payment header — authentication failure
- Service unavailable on dev environment — 5xx error

## How this service works

## Output
