The Overpass API (formerly known as OSM Server Side Scripting, or OSM3S before 2011) is a read-only API that serves up custom selected parts of the OSM map data. It acts as a database over the web: the client sends a query to the API and gets back the data set that corresponds to the query.
The Overpass API offers a variety of search possibilities. This is also known as querying. The results of those searches or queries can be displayed directly on a map, but it is also possible to retrieve only the data. On this page we will focus on examples that have to be displayed on a map.
Overpass API allows you to query for OSM data by your own search criteria. For this purpose, it has two specifically crafted query languages: Overpass XML, and Overpass QL. The basic semantics of Overpass API is that flows of OSM data (nodes, ways...) are generated and modified by statements, which are executed one after another.
Overpass QL is a procedural, imperative programming language written with a C style syntax. This wiki page intends to be a complete technical reference to the structure of Overpass QL. For a collection of practical examples, see also the wiki page Overpass API by Example.
Overpass API(以前の別名：OSM Server Side Scripting、あるいは2011年以前はOSM3S)とは読み出し専用のAPIであり、OSM地図データの中から個別に選択された部分を取り出します。Webを介したデータベースとして動作します。
Overpass API/Installation. Other languages... This page tells you how to install the OSM3S server such that you can use it as a local OSM mirror. Additional functionality like management of areas and the line diagram utils aren't covered yet.
Overpass API v0.7.61. Release date: 2023-07-17. The release introduces two new variants for recurse: way_cnt and way_link. This allows to select nodes that are intersections of ways within one given set.
If you just want to embed a map into a webpage, you don't want this API. Use a web map library instead. Alternatively, consider the Overpass API which provides read-only API access.
Areas are an extension of Overpass API: They constitute a new data type area beside the OSM data types node, way, and relation. So this data is not extracted and updated from the main API, but computed by a special process on the Overpass API server.
