## 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 jnd-token-purchase-1-usdc-x420-dev-4e6c18a1

Example prompt: Buy me 1 USDC worth of JND tokens on x420.dev — use the JND contract at 0x5F2F67A5155f6dD054c768e03fD6bADBC635aB07 and let me know how many tokens I receive and the transaction hashes.

## When to prefer this

Use this endpoint when you want to purchase a small (1 USDC) amount of JND tokens programmatically via the x402 payment protocol. Prefer this over the 5 USDC sibling endpoint when minimizing spend per call or testing the token purchase flow.

## Known failure modes

- Insufficient USDC balance — payment of 1 USDC cannot be completed
- Token contract unavailable or paused — swap transaction fails
- Network congestion causing transaction timeout
- Invalid wallet address or payment header missing
- Swap slippage too high causing transaction revert
- API server unreachable or rate-limited
