Get Transactions In Block

POST

Retrieves the list of transactions within a specific block.

🚧 Caution when using decodeInput

The decodeInput field decodes the transaction's input field and provides the result. However, different functions can use the same function selector, so the provided result may not match the actually called function. Therefore, additional verification is recommended for functions that differ from ERC standard specifications.

Path Parameters

chainstringrequired

Parameter specifying the target chain to query.

networkstringrequired

Parameter specifying the network of the target chain.

Request Body

blockstringrequired

Parameter specifying the point in time for balance query. You can enter block hash, block number, or block tag.

block number: Enter as a decimal string.
block hash: Enter as a 64-character hexadecimal string, excluding the 0x prefix.
block tag: Enter "earliest" or "latest"; "latest" queries the balance of the most recent block.

pageinteger

The page parameter specifies the data page to query. It accepts values up to 100; for pages exceeding 100, use the cursor pagination method.The page and cursor parameters cannot be used together. If both page and cursor are empty, cursor pagination is used.

rppinteger

rpp stands for results per page and specifies the page size. You can specify a number greater than 0 and up to 100.

cursorstring

The cursor parameter supports pagination and data navigation between pages. Provide the cursor value from the previous page in the next request to load the next page of data.The page and cursor parameters cannot be used together. If both page and cursor are empty, cursor pagination is used.

withCountboolean

Parameter specifying whether to include the count field in the response. The count field indicates the total number of requested data items. When set to true, the count field is included and response speed may be slower.

withLogsboolean

Parameter specifying whether to include the logs field in the response. Response speed may be slower when set to true.

withDecodeboolean

Parameter specifying whether to include decodedInput and decodedLog fields in the response. Response speed may be slower when set to true.decodedLog is part of logs, so it is not included when withLogs is false even if withDecode is true.decodedInput interprets the transaction input field and provides the result. However, different functions may use the same function selector, so the result may not match the actually called function. Additional verification is recommended for non-standard ERC functions.

Responses

pageinteger

Field representing the page number specified in the page parameter. This field is only included in the response when a value greater than 0 is specified for the page parameter.

rppinteger

Field representing the number of results per page specified in the rpp parameter.

cursorstring

A field for cursor pagination. This value must be provided in the next request to load the next page of data.

countinteger

Field representing the total count of requested data. This field is only included in the response when true is set for the withCount parameter.

transactionHashstringrequired

Unique hash value that identifies the transaction. This field has a 64-character hexadecimal string format excluding the prefix (0x).

transactionIndexintegerrequired

Order in which the transaction was included within a specific block; indicates the execution order of the transaction.

transactionTimestampintegerrequired

blockNumberintegerrequired

Unique number of the block. This number indicates the order in which the block was created on the blockchain.

blockTimestampintegerrequired

Timestamp of when the block was created, provided in milliseconds. Stored in Unix timestamp format.

refBlockBytesstringrequired

Indicates the block referenced by the transaction. This field uses the 6th to 7th bytes of the reference block number, totaling 2 bytes. The reference block is the most recently finalized block; this value is embedded in the transaction to prevent transaction replay.

refBlockHashstringrequired

Indicates the block referenced by the transaction. This field uses the 8th to 15th bytes of the reference block hash, totaling 8 bytes. The reference block is the most recently finalized block; this value is embedded in the transaction to prevent transaction replay.

typeUrlstringrequired

Field that specifies the specific path of the transaction type. This field is used to identify transaction types defined in chain buffer format.

isMultiSigbooleanrequired

Field indicating whether the transaction is a multi-signature transaction. Multi-sig requires signatures from multiple accounts and is used to enhance security.

Represents the sender address that created the transaction. That is, the account address from which the transaction originates. This field has a 34-character base58 string format starting with "T".

tostringrequired

Represents the recipient address that will receive the transaction. Depending on the transaction type, this may mean the address receiving the transferred TRX or the smart contract being invoked. This field has a 34-character base58 string format starting with "T".

valuestringrequired

Represents the amount of assets transferred in the transaction. These assets include TRX or TRC10 tokens. * The type of asset transferred depends on the "assetId" field value. When "assetId" is 0, it represents the TRX amount; when non-zero, it represents the amount of a specific TRC10 token. The amount is expressed in the smallest unit (e.g., sun for TRX) as a decimal string.

assetIdintegerrequired

Represents the data or input value passed when invoking a smart contract. Primarily used as parameter values for smart contract functions, specifying the actions the contract should perform.

functionSelectorstringrequired

Represents the unique identifier of the function executed in the transaction. For example, the signature of the transfer(address,uint256) function generates a specific hash through Keccak-256 hashing, and the first 4 bytes of this hash are used as the function selector.

resultstringrequired

Indicates the final status of the transaction execution. Provides the overall result of whether the entire transaction was processed successfully, allowing users to easily verify if the transaction completed successfully. Status values are SUCCESS and FAILED.* Even if smart contract execution fails, the transaction itself is considered successful if it was recorded on the blockchain.

contractRetstringrequired

Indicates the smart contract execution result, providing more detailed information about the transaction success or failure.

Examples: SUCCESS, REVERT, BAD_JUMP_DESTINATION, OUT_OF_MEMORY, PRECOMPILED_CONTRACT, ...

resMessagestringrequired

When transaction execution fails, represents the failure reason or error message. Returns an empty string for successful transactions.

feestringrequired

Total TRX cost consumed during transaction execution. When the bandwidth and energy of the account that created the transaction are insufficient, the shortfall is covered in TRX. This field represents that shortfall and is the sum of netFee and energyFee. For example, if bandwidth and energy are sufficient, fee is 0. Otherwise, it indicates the amount of TRX consumed to cover the shortfall. The unit of this field is "sun", and 1 TRX = 1,000,000 sun.

feeLimitstringrequired

Maximum fee limit set by the user when creating the transaction; specifies the upper limit of fees that can be consumed when the transaction is executed. If the actual fee used exceeds feeLimit, the transaction fails. This allows users to prevent unexpected high fees in advance. The unit of this field is "sun", and 1 TRX = 1,000,000 sun.

netFeestringrequired

netUsagestringrequired

Amount of bandwidth actually used in the transaction. When the transaction creator's remaining bandwidth is insufficient, the shortfall is paid in TRX, and the amount paid is recorded in netFee.

energyFeestringrequired

Represents the cost paid in TRX when the energy of the transaction creator's account is insufficient. Only incurred when the energy required for smart contract execution exceeds the creator's available balance. The unit of this field is "sun", and 1 TRX = 1,000,000 sun.

energyUsagestringrequired

Amount of energy used from the transaction creator's account.

originEnergyUsagestringrequired

Represents the amount of energy used from the account that deployed the smart contract. In certain situations, the contract deployer may bear some of the energy cost.
