Arc Payment API
Did that Arc payment actually land? Pass ?tx=0x… and optionally ?to=0x… and ?expect=1.50 to get the payer, the amount, whether it reached your address, confirmations, finality and the gas paid — all in USDC. Handles the thing that breaks most Arc integrations: USDC is the NATIVE gas token at 18 decimals in tx.value AND has a 6-decimal ERC-20 view, so a verifier that only reads Transfer logs reports real payments as zero. Read-only: checking never consumes the payment.
