EstimateEnergy

POST

Estimate the energy required for the successful execution of smart contract transactions. (Confirmed state)

Path Parameters

chainstringrequired

Parameter specifying the target chain to query.

networkstringrequired

Parameter specifying the network of the target chain.

Request Body

owner_addressstringrequired

Transaction initiator address. (Format: Base58 or Hex)

contract_addressstringrequired

Contract address. (Format: Base58 or Hex)Example: TG3XXyExBkPp9nzdajDZsozEu4BkaSJozs

function_selectorstring

Function selector.Example: transfer(address,uint256).

parameterstring

ABI-encoded function parameters (Hex String).Example: 000000000000000000000000a614f803b6fd780986a42c78ec9c7f77e6ded13c

datastring

This field transmits the necessary data for smart contract interaction, including the function being called and its parameters. You may choose to use the data field, which contains the complete ABI-encoded information, or use the function_selector and parameter fields separately. Note that if both data and function_selector are present, the system will prioritize using the function_selector and parameter fields for the contract interaction.

call_valueinteger

Amount of TRX transferred into the contract. (Unit: sun)

call_token_valueinteger

Amount of TRC-10 token transferred into the contract.

token_idinteger

TRC-10 token ID

visibleboolean

Optional. Set to true to format addresses in Base58; set to false for hex format. (Default: false)

Responses

Result of the contract execution simulation.

resultboolean

Result of the contract execution simulation.

constant_resultarray

Contract execution result. Contains the ABI-encoded return value as a hex string.

codestringrequired

Code identifying the cause of the failed request.

messagestringrequired

Detailed message including the name and value of the invalid parameter.
