Example prompt: Buy me $5 worth of FISH tokens using USDC on x420 — the one that swaps into the 0x30bd83Da6d60aF29cC82F9a7813e78E6eFD9Db07 contract and gives me back the transaction hashes.

## When to prefer this

Use this endpoint when an agent needs to purchase exactly $5 USDC worth of FISH tokens in a single atomic call with on-chain transaction receipts. Prefer the $1 sibling endpoint for smaller test purchases or when budget is limited. This endpoint is ideal when the user wants a meaningful position in FISH without manually navigating a DEX.

## Known failure modes

- Insufficient USDC balance — payment of $5 USDC cannot be fulfilled
- Smart contract swap failure — swapTransactionHash may be null if DEX execution fails
- Network congestion or RPC errors causing transaction timeout
- x402 payment protocol rejection if authorization header is invalid or missing
- Token liquidity insufficient for swap at time of call
