Mapsource.io
Mapsource (mapsource.io) is a commercial hosted geospatial API service providing access to OpenStreetMap data, map tiles, place search, routing, terrain data, spatial analysis, and related developer services.
Services
OpenStreetMap queries
- Hosted Overpass API-compatible queries using standard Overpass QL
- Nodes, ways, relations, generated areas, tags, geometry, recursion, and metadata
- JSON, XML, and CSV output
Maps
- Raster basemap tiles using CARTO Dark Matter and Positron styles
- Vector tiles using the OpenMapTiles schema
- Custom MapLibre-compatible basemap styles
- Static PNG map rendering
Search
- Address and place search
- Business and brand search
- Autocomplete
- Reverse geocoding
- Regional OpenStreetMap POI discovery
Routing and navigation
- Turn-by-turn routing
- Travel-time and distance matrices
- Isochrones
- Map matching
- Road-network snapping
- Multi-stop route optimization
Routing is computed from OpenStreetMap data using Valhalla.
Terrain and analysis
- Point elevation
- Terrain tiles
- Contour generation
- Geometry buffering, measurement, intersection, combination, and simplification
- Multi-step geospatial compute pipelines
Agent access
Mapsource also exposes its search, navigation, analysis, rendering, terrain, and OpenStreetMap query services through the Model Context Protocol (MCP).
API access
Mapsource is a subscription service. Authenticated APIs use an API key sent as an HTTP Bearer credential.
The Overpass interpreter is available at:
https://mapsource.io/api/interpreter
For existing Overpass clients that cannot set request headers, Mapsource also provides a path-key compatibility endpoint:
https://mapsource.io/api/YOUR_API_KEY/interpreter
Data and attribution
OpenStreetMap query and routing data is derived from OpenStreetMap and is subject to the Open Database License.
Basemap vector tiles use the OpenMapTiles schema and OpenFreeMap-distributed map data. Raster basemaps include CARTO Dark Matter and Positron styles.
