Estimate USDT Transfer Energy
GET/calculator/estimate-energy/usdt/:from_address/:to_address
The fastest way to estimate a USDT transfer: pass the sender and receiver right in the URL and get back the exact energy it will burn — perfect for a quick lookup or a copy-paste link.
It runs the same on-chain simulation as the Energy Estimator, with the USDT contract (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t) wired in for you. Need a different TRC20 token? Use the full Energy Estimator endpoint instead.
Good to know
- Energy prices move in real time — round the returned value up when placing an order
- Rate limits: 10 req/min per IP, shared by both estimator endpoints (
429), and 60 req/min shared to the TRON node (503)

Successful Response
Invalid TRON address — detail is a string, e.g. Invalid TRON address format: …. A missing required parameter returns a detail array of field errors instead.
Rate limit exceeded — more than 10 requests/min from your IP, counted across both estimator endpoints
The TRON node could not simulate the transfer (contract error, invalid transaction, etc.)
The global outbound rate limit to the TRON node is exhausted — retry shortly
