Example prompt: Buy me $5 worth of STARS tokens using the Interstellar Way service on x420.dev — the contract is 0x970045293f3a163C933C1791e1803e4a9bF07B07 and I want to see how many tokens I receive and the swap transaction hash.

## When to prefer this

Use this endpoint when you need to purchase exactly $5 USDC worth of STARS tokens in a single API call via the x402 payment protocol; prefer the $1 sibling endpoint if you want smaller incremental purchases or want to test with lower spend

## Known failure modes

- Insufficient USDC balance to cover $5 payment — payment rejected
- x402 payment protocol error — facilitator unable to process transaction
- Token swap fails on-chain — swapTransactionHash may be null with error message
- Smart contract address unreachable or liquidity insufficient — tokens not delivered
- Network congestion causes timeout — transaction may be pending with null hashes
