## 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 x420-chill-house-buy-1-usdc-of-chill-tokens-c0ebb48b
```

Example prompt: Buy me 1 USDC worth of CHILL tokens from X420 Chill House right now.

## When to prefer this

Use this endpoint when an agent needs to programmatically acquire a small amount of CHILL tokens by spending exactly 1 USDC via the x402 payment protocol, without needing a full DEX integration. Prefer this over the 5 USDC sibling endpoint when only a minimal purchase is required.

## Known failure modes

- Payment not provided or x402 payment header missing — returns 402 Payment Required
- Insufficient USDC balance to cover the 1 USDC cost — transaction fails
- On-chain swap fails due to liquidity or slippage — swap transaction hash may be null and tokens not received
- Network congestion causes transaction timeout — sendTransactionHash present but swapTransactionHash null
- Invalid or expired payment — payment rejected before swap executes
