OsmSharp.IO.API

This is a simple C# client to allow using OSM API easily over REST. Please read the API's documentation and use it responsibly. Misuse can have an adverse affect on the OSM ecosystem. Pull requests are welcome. You will need VisualStudio, VS Code or Rider to modify this project.

Features

• Supports Logging using ILogger
• Supports Authentication with OAuth 2
• Supports every documented operation of the Osm Api v0.6 (as of September 2026)
• Is thread safe

Example Usage

// Create a client factory (pointing at the dev server)
var clientFactory = new ClientsFactory(null, new HttpClient(),
	"https://master.apis.dev.openstreetmap.org/api/");
// After testing, use "https://www.openstreetmap.org/api/" for production

Get a Node

var client = clientFactory.CreateNonAuthClient();
var node = await client.GetNode(100);

Delete a Node (map changes require OAuth)

var authClient = clientFactory.CreateOAuth2Client("oAuth-token");
var changeSetTags = new TagsCollection() { new Tag("comment", "Deleting a node.") };
var changeSetId = await client.CreateChangeset(changeSetTags);
node.Version = await client.DeleteElement(changeSetId, node);
await client.CloseChangeset(changeSetId);

See the functional tests for examples of each operation.
