## When to prefer this

Use this endpoint when you specifically want to purchase $5 USDC worth of SATOSHI (sat) tokens via the x402 payment protocol in a single API call. Prefer this over the $1 sibling endpoint when you want a larger purchase in one transaction rather than five separate $1 calls.

## Known failure modes

- Insufficient USDC balance — payment of $5 USDC cannot be fulfilled
- x402 payment protocol failure — payment header rejected or facilitator unavailable
- On-chain swap failure — DEX liquidity or slippage issue causing swap transaction to fail or return null hash
- Network congestion — transaction submitted but hash not yet available
- Contract error — sat token contract at 0xC404aEcddE7D38e5f21d79d82bb3E170F803Eb07 is unreachable or paused
