The current API estimates only TRON Energy costs; it does not include Net (bandwidth) costs.

The following estimation scenarios are supported:

  • Standard token transfers: Do not provide amount or data.
  • Contract invocation transactions: Provide the ABI-encoded data (in hex format).

​
Request Parameters

​
receive_address
string
required

receive addres

Please ensure that the received address holds the token corresponding to the contracted_address, otherwise the miner fee estimation will fail

​
address_to
string
required

The transfer address for estimating miner fees.

  • Standard token transfer scenario: address_to is the actual recipient address.
  • Contract invocation transaction scenario: address_to is the contract address, and it must match contract_address.
​
contract_address
string
required

Contract address for estimating miner fees.

​
service_charge_type
string
required

rent time code: Request the order/price interface to return the cost codes for minutes, hours, days, and different times.

eg:10010 - 10 minutes, 20001 - 1 hour, 30001 - 1 day

​
amount
string

Contract invocation amount

When used for contract estimation scenarios, amount represents the value associated with the contract invocation. This parameter is optional for standard transfer estimation scenarios.

​
data
string

Contract invocation data; hexadecimal data constructed via ABI encoding.

If data is provided, the API treats the request as a contract transaction for resource estimation; this parameter is optional for standard transfer estimation scenarios.
