## 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 interstellar-way-stars-token-purchase-1-usdc-x420-dev-33b9867a
```

Example prompt: Buy me 1 USDC worth of STARS tokens on Interstellar Way and let me know how many tokens I received and the transaction hashes.

## When to prefer this

Use this endpoint when an agent needs to acquire a small amount of STARS tokens (contract 0x970045293f3a163C933C1791e1803e4a9bF07B07) for exactly 1 USDC via the x402 micropayment protocol. Prefer this over the 5 USDC sibling endpoint when only a minimal token purchase is needed or when testing the integration.

## Known failure modes

- Insufficient USDC balance — payment fails, no tokens received
- x402 payment gateway rejects transaction — returns error message
- Swap transaction fails on-chain — swapTransactionHash may be null with error message
- Network congestion causes timeout — transaction may be pending
- Invalid or misconfigured wallet — sendTransactionHash null, no swap executed
