Overpass API
A read-only API interface within the OpenStreetMap ecosystem designed specifically for geographic data queries. It supports SQL-like syntax for fine-grained filtering of geographic features, making it suitable for extracting walking-related attributes such as surface type, gradient, and accessibility properties within defined areas.

The Overpass API is a read-only interface for data queries in the OpenStreetMap ecosystem, supporting the filtering and extraction of geographic features in specific areas through SQL-like syntax with conditional criteria.
During Overpass testing, kumi.systems returned a 500 error, overpass.osm.ch returned HTML with a 200 status, and only overpass-api.de actually returned data.
A mirror that returns HTTP 200 with no data produces an empty array; because an empty array in JS is truthy it is treated as a success, causing Doorstep to silently save an empty map—this bug originated from a default value of [].
