Verify USDC payments and balances on Base mainnet: check_payment, get_balance, decode_tx.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
