Data Coverage	USA, Canada
Included With	API, Flex
Update Interval	Ten Minutes

Supported Actions

The following actions are supported with the fires endpoint:

:id	Requesting data by using the :id action is used for returning data for a particular item that has an ID associated with it. This is the primary method for requesting general weather information for a single location (observations, forecasts, advisories, etc.) as the location's name or a zip code serves as the id. Other endpoints may expect a certain value for the ID, such as storm cells whose ID value is a combination of the radar site identifier and unique identifier assigned to every storm cell. Refer to an endpoint's detailed documentation for specific information regarding how to use the :id action.
closest	The closest action will query the API for data that is closest to the requested place and return the results, if any, in order from closest to farthest. If no limit is provided in the request, then only the closest single result will be returned. If your request does not return results, you may try setting or increasing the radius being used.
within	The within action allows for returning data within a variety of different geometrical regions. Currently supported geometries include a circle (requires a center point and radius), rectangle (requires two coordinate points defining the top-left and bottom-right corners) and polygon (requires at least three coordinate points). Unlike the closest action, the results will not be returned in any particular order based on distance.
search	The search action is used as a more general query method and expects the query to be defined with the custom query for the request. Unlike the closest action, results will not be returned in any particular order.

Supported Parameters

The following parameters are optional unless otherwise noted:

p	`p=:place`	Defines the location to query data for. Refer to the list of supported place value formats.
limit	`limit=:total`	The total number of results to return as an integer. Each endpoint may have a set maximum for this value depending on usage. The default limit is 1 if not specified. The maximum limit for this endpoint is 250.
radius	`radius=:distance:unit`	When requesting the closest results within a circle, the radius determines how far from the specified location to search. A valid unit value must be included in your radius value, e.g., "5mi", "10km", "25miles". If no unit is provided, your value is assumed to be in meters by default. Most endpoints utilize a default radius of 50 miles, though some endpoints, such as lightning, may have tighter restrictions specified.
minradius	`minradius=:distance:unit`	When requesting the closest results within a circle, the minradius determines how far from the specified location to search to begin searching results. A valid unit value must be included in your minimum radius value, e.g., "5mi", "10km", or "25miles". If no unit is provided, your value is assumed to be in meters by default. When combined with the radius parameter, donut style queries can be made for point data, such as lightning.
query	`query=:string`	Used to filter results based on certain fields in the data set. See Advanced Queries for more details.
sort	`sort=:string`	Used to sort results based on certain fields in the data set. See Sorting for more details.
skip	`skip=:number`	Used to skip over a specific number of results in the data set.
fields	`fields=:string`	Provides a comma separated list of values for the API to return. This parameter is often used to limit the amount of data returned. See Reducing Output.

Supported Filters

The following filters can be passed to the filter parameter to reduce the results that are returned:

geo	Include the fire coverage perimeter information and polygon when available. Note fire perimeters are normally available for some, but not all, large US fires.
hasperimeter	Return only fires that have perimeter information.
hasnoperimeter	Return only fires that do not include perimeter information.

Supported Query Properties

Use the following supported property keys when creating custom queries for your requests:

id	The reported fire ID.
dt	The date of the fire.
area	The area of the fire in acres.
name	The closest city to the fire observation.
state	The state of the closest city to the fire observation.
country	The country of the closest city to the fire observation.
conf	The confidence of the fire as a percentage.

Sortable Fields

Default Sort: dt (desc)

You can use the following fields to sort data. Review the sorting docs page for more information on the sort functionality.

id	Sort based on the fire ID.
dt	Sort based on the date time of the fire report.
area	Sort based on the area of the fire in acres.
name	Sort based on the closest city name.
state	Sort based on the state of the closest city.
country	Sort based on the country of the closest city.
conf	Sort based on the confidence of the fire.
