Paygo

Paygo: exact fee quote for one token transfer

Partner API (wallet integrations). Returns an exact, fixed-price fee quote for a specific sender→recipient TRC-20 transfer, computed by live simulation on the TRON node (recipient storage state and the TIP-491 dynamic energy factor included). The quoted feeTrx is final: the user signs a TRX payment for exactly this amount. Requires a partner API key enabled for paygo.
