This API is especially useful for gauging the size of extracts before sending to clients (desktop or mobile).
Downloading and processing large amounts (10-50MB+) of GeoJSON on mobile or old devices can significantly
impact the end user experience.
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
This endpoint requires the growth plan because it uses thousands of expensive geometric operations.
Body
This request takes a single WKT geometry as thePUT request body (ASCII/UTF8 encoded).
Coordinates are in WGS84 (EPSG:4326) and ordered longitude, latitude. All counted geometries
will intersect with the uploaded geometry.
Request Parameters
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.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, withContent-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.
number
The number of features matching the filter tags and bounding box.
number
The size of the GeoJSON response, in bytes, that one would get if the same query
were used to extract features from OSM inside a polygon.
error field describing the cause.
string
The error message if the extract request parameters were incorrectly formatted.This response field will not be present if the extract succeeds.
