Query parameters
eventsanyOptional

events is the list of transaction event type. Deprecated post v0.47.x: use query instead, which should contain a valid events query.

pagination.keyanyOptional

key is a value returned in PageResponse.next_key to begin querying the next page most efficiently. Only one of offset or key should be set.

pagination.offsetanyOptional

offset is a numeric offset that can be used when key is unavailable. It is less efficient than using key. Only one of offset or key should be set.

pagination.limitanyOptional

limit is the total number of results to be returned in the result page. If left empty it will default to a value to be set by each app.

pagination.count_totalanyOptional

count_total is set to true to indicate that the result set should include a count of the total number of items available for pagination in UIs. count_total is only respected when offset is used. It is ignored when key is set.

pagination.reverseanyOptional

reverse is set to true if results are to be returned in the descending order.

Since: cosmos-sdk 0.43

order_byanyOptional
  • ORDER_BY_UNSPECIFIED: ORDER_BY_UNSPECIFIED specifies an unknown sorting order. OrderBy defaults to ASC in this case.
  • ORDER_BY_ASC: ORDER_BY_ASC defines ascending order
  • ORDER_BY_DESC: ORDER_BY_DESC defines descending order
pageanyOptional

page is the page number to query, starts at 1. If not provided, will default to first page.

limitanyOptional

limit is the total number of results to be returned in the result page. If left empty it will default to a value to be set by each app.
