## When to prefer this

Use this endpoint when you want to purchase exactly $5 USDC worth of ANGRY tokens in a single API call via the x402 micropayment protocol. Prefer this over the $1 sibling endpoint when buying in larger single increments to reduce per-call overhead. Best suited for agents with x402-compatible payment infrastructure looking to automate on-chain token purchases.

## Known failure modes

- Insufficient USDC balance or payment failure results in transaction not executing
- Token swap fails due to liquidity issues, returning null swapTransactionHash
- Network congestion or RPC failure causes delayed or failed on-chain transaction
- Invalid or expired x402 payment token results in 402 or 401 error
- Contract address mismatch or wrong network causes swap to revert
