## When to prefer this

Use this endpoint when you want to buy exactly $5 USD worth of pr tokens in a single API call using the x402 payment protocol. Prefer this over the $1 sibling endpoint when you want a larger purchase in one transaction rather than multiple smaller ones.

## Known failure modes

- Insufficient USDC balance — payment of 5 USDC cannot be completed
- Smart contract failure — swap transaction reverts on-chain
- Network congestion — transaction not confirmed in time
- Invalid payment — x402 payment header rejected
- Token contract unavailable — 0x87f0c380Dae2d33264350cf5307E765B123deB07 not accessible
- Slippage too high — swap fails due to price movement
