Request Parameters

​
tags
string
required
All features counted will satisfy each of the passed tags given by this parameter. tags is formatted as a list of tags, each like key=value.You can create a tag list by forming an array of key=value items and joining them into one string with the & character.This list must be URL encoded because both = and & are reserved characters in URI.An example list of tags could be leisure=park and name=Westglen Park. This matches parks that have the name Westglen Park. To set this parameter, we’ll URL encode leisure=park&name=Westglen Park.Documentation on tags can be found on the TagInfo resource website.
​
bbox
string
default:"None"
This is the bounding box for counted features. The coordinates (in EPSG:4326) of the bounding box are required to be in (minimum longitude, minimum latitude, maximum longitude, maximum latitude) order. Coordinates are expressed as signed floats joined by commas.An example bounding box in the US could be -108.984375,32.026706,-103.051758,37.195331.You can create a bounding box on bboxfinder, or in shapely by invoking the bounds property on a geometry.
​
api_key
string
required
Your account’s API key. You can create an API key by registering for an account and copy and paste it from your account dashboard.

​
Response

When features are successfully counted, a 200 OK response will be issued, with Content-Type: application/json. The body will have a property feature_count which will be an unsigned integer representing the number of features matching the tags and bounding box.
​
feature_count
number
The number of features matching the filter tags and bounding box.
​
response_bytes
number
The size of the GeoJSON response, in bytes, that one would get if the same query were used to extract features from OSM.
In the event of an error, an error response will be issued, usually with a 5xx error code. The error will be JSON-formatted, with an error field describing the cause.
​
error
string
The error message if the extract request parameters were incorrectly formatted.This response field will not be present if the extract succeeds.
