Static outdoor layers

Static layers are versioned snapshots served as raster or vector tiles from PMTiles archives. 0.2 credits per tile; metadata is free.

GET /v1/static/{layer}/{z}/{x}/{y}.{mvt|png}
GET /v1/static/{layer}/metadata

Empty tiles return 204. The metadata document carries format, minzoom, maxzoom, bounds, the vector source-layer names and attribution, so nothing needs hard-coding.

Slope tiles are value-encoded like weather tiles: decode degrees from the red channel and colour with your own ramp (or the stops in metadata).

GET /v1/peaks/manifest.json (free) → the current release with checksums and a cell index; GET /v1/peaks/{version}/cells/{lon}_{lat}.json → the named peaks in a 1° cell with elevation, prominence where known, and the OpenStreetMap node id. 71,000 peaks across CONUS. ODbL.

Government sources are public domain and need no attribution. trails-mt, peaks and any layer whose metadata says so require “© OpenStreetMap contributors” wherever they are displayed. See Attribution.
