Tron USDT Transfer Watch

Watch a Tron address for USDT and USDC (TRC-20) transfers in a loop: each call returns only transfers since your last call with amount, direction, counterparty, time and link, plus the TRX balance. First call covers the last hour (lookback_hours up to 6) and returns a cursor; pass it back next time. For deposit detection and payment confirmation on Tron.

Run free trial ↗3 free calls per day with the example input. Paid: $0.002 USDC, no limit.
