How this service works

Example use cases
Automated BNB gas top-up
“My wallet is running low on BNB for gas fees — go ahead and swap 1 USDC for BNB and send it to my wallet right now, then tell me how much BNB I got and share the transaction hash.”
Test on-chain stablecoin swap
“I want to test a live USDC-to-BNB swap on-chain — execute the exchange of 1 USDC for BNB to my address and confirm the amount of BNB received along with the transaction details.”
Recurring micro BNB purchase
“As part of my daily DCA routine, go buy 1 USDC worth of BNB for me right now and report back with how many BNB tokens landed in my wallet and what the swap transaction hash is.”
Technical details
Endpoint
GEThttps://bnb.x420.dev/api/puffWhen to prefer
Use this endpoint when you need to acquire a small amount of BNB (Binance Coin) by spending exactly 1 USDC, especially in automated or agent-driven workflows that support x402 micropayment protocol. Prefer the 5 USDC sibling endpoint if you need a larger BNB purchase in a single call.
Side effects
- Payment not received or USDC balance insufficient — transaction fails with error message
- Swap fails due to low liquidity or slippage — swapTransactionHash is null and message contains error
- Network congestion causes timeout — sendTransactionHash returned but swapTransactionHash null
- Invalid wallet address configured — transaction cannot complete
- x402 payment protocol error — 402 response before API call is processed
