Layers
Each layer is produced by one pipeline topic and can be queried through GET /layers/{id}/features, used in search filters, and, where marked, rendered as vector tiles. GET /layers returns this list live, with feature counts and refresh dates. The last column links to each layer's page on zonio.tech, with a description, the publisher and a live map preview.
Served via: api: queryable through the REST API and MCP · tiles: also a PMTiles archive · wms: proxied raster.
