POSTGet Transactions In Slot

Data APIhttps://web3.nodit.io/v1/solana/mainnet/blockchain/getTransactionsInSlot

Retrieves the list of transactions included in a specific slot.

Path Parameters
chainstring (enum)required

Parameter to specify the target chain for the query.

networkstring (enum)required

Parameter to specify the network of the target chain. Supported networks may vary depending on the chain.

Request Body
slotstringrequired

Parameter specifying the slot to query. You can enter one of the following formats:

  • slot height: Enter the slot number as a decimal string.
  • slot tag: Use "earliest" or "latest" to specify the first slot or the latest slot.
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.

withBalanceChangesboolean

Parameter specifying whether to include the balanceChanges field in the response.

  • balanceChanges is a field that contains the balance changes of the Native token (SOL) and Token.
  • Setting this parameter to true may slow down the response.
withInstructionsboolean

Parameter specifying whether to include the instructions field in the response.

  • instructions is a field that contains the list of instructions in the transaction.
  • When this parameter is set to true, instructions are included in the response.
  • instructions are not provided for failed transactions (status "failed").
