## 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-dev-5d8f699a
```

Example prompt: Buy me $5 worth of x420 tokens using USDC right now.

## When to prefer this

Use this endpoint when a user specifically wants to purchase $5 USDC worth of x420 tokens in a single transaction. Prefer this over the $1 USDC variant when a larger purchase is desired in one call. This is appropriate for agents operating with crypto payment capabilities (x402 protocol) wanting to automate x420 token acquisition.

## Known failure modes

- Insufficient USDC balance — payment cannot be completed
- Payment protocol failure — x402 payment not accepted
- Token unavailability — x420 tokens temporarily out of stock or contract error
- Network error — blockchain or API connectivity issue
- Invalid payment — malformed or rejected USDC transaction
