Search Stats

last updated: September 04, 2024

Search Stats gives you a quick way to determine the number of items which meets your search specifications. This endpoint allows you to specify a time interval and search filter and returns a histogram of item counts, grouped by interval, which match your filter criteria.

This endpoint can be used to answer questions such as:

  • How does availability of imagery with less than 10 percent cloud cover change seasonally in Jakarta?
  • How deep is Planet’s 2019 SkySat archive over Shanghai?
  • How many items which meet my search criteria are published each hour?

Request Body

The body of a stats request must include a search filter and time interval.

  • filter (required): is your structure search criteria; you can read more on supported filters on our Search Filters page
  • interval (required): specifies the time interval of the returned histogram buckets; ”hour”, ”day”, ”week”, ”month”, or ”year”
  • item_types (required): limits results by item type(s)
  • utc_offset (optional): offsets the start time of your histogram buckets to match your desired timezone (ISO 8601 UTC offset, ex. +1h or -8h)
