If provided without fromBlock, results are queried from genesis block to this block.
toBlock value cannot be less than fromBlock value.
If fromBlock and toBlock have the same value, only that block is queried.
"earliest" for toBlock is only allowed when fromBlock is "earliest".

This field cannot be used together with fromBlock and toBlock.
If fromDate and toDate are not provided, the API queries data from the latest 30 days.

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.

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.

Field representing the actual range applied to the query. The same kind of values used in the request's range parameters are returned. A Date-based request returns fromDate and toDate, a Block-based request returns fromBlock and toBlock, and a Ledger-based request returns fromLedger and toLedger; different kinds are never mixed in a single response. When all range parameters are omitted, a default window of the last 30 days is applied and fromDate, toDate are returned. Block and Ledger values are always returned as heights (numbers), even if a hash or tag (latest, earliest) was provided in the request.

toDatestring

Field representing the end of the query range in Date mode. Returned in ISO 8601 format.
