Is boundary-atlas live?

Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.

Is boundary-atlas free to use?

Yes — the hub reached it with no key and no payment.

What tools does boundary-atlas have?

10 tools: nearest_geographies, search_geographies, get_geography, related_geographies, list_children, list_geographies, locate_point, get_boundaries, ….

Is boundary-atlas safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• data_freshness open 3h ago

  When each upstream dataset was last fetched and checked, what period it describes (vintage), how often it is re-checked, and whether it is overdue. Includes the recent refresh history.

• nearest_geographies unknown never probed

  Geographies at `level` whose internal point is closest to (lat, lon). This is a nearest-point approximation, not point-in-polygon. To find the geography containing a point, use locate_point.

• related_geographies unknown never probed

  Links between geographies that overlap without nesting, with population shares. Districts: for a precinct, county, town, city (place) or ZIP, the congressional, state senate and state house districts it falls in; for a district, the precincts, counties, towns, cities or ZIPs inside it (filter with `level`, e.g. 'precinct'). A city ('us:place:1714000') also lists its counties. A ZIP ('us:zcta:07102') lists the cities, counties, towns, precincts and districts it overlaps. Ask for `level='zcta'` on a city, county, town or district to list the ZIP codes in it. `weight` is the share of the smaller unit's 2020 population inside the other (for a ZIP, the share of the ZIP's residents in each unit; 0 for parts with land but no residents). relation 'within' means wholly inside (1.0), 'overlaps' means split, 'approximate' means the unit was too small to contain any 2020 block's internal point and was placed by the nearest block. Use min_weight to drop slivers. ZCTAs approximate USPS ZIP Codes.

• locate_point unknown never probed

  Which geographies contain a point: precinct, county, town, congressional and state legislative districts in the US; province, census division and subdivision, federal riding, polling divisions and provincial districts in Canada. Point-in-polygon on stored boundaries (simplified to ~10 m, so a point within ~10 m of a line can land on either side). Geocode an address to lat/lon first. levels: restrict to some levels (default: all except 'vtd_2020'). If a point is just outside every shape of a level that its state/province has (a pier, a beach, a gap between precinct files), it is matched to the nearest shape of that level in the same state/province within ~1 km and flagged approximate=true with distance_m. not_found lists levels the state/province has data for but no shape here; no_data lists levels with no boundaries there at all (e.g. Nebraska has no state house; Ontario has no provincial polling divisions here).

• get_boundaries unknown 3h ago

  Polygon boundaries as a GeoJSON FeatureCollection (EPSG:4326, RFC 7946 winding), for drawing dashboard maps. id: the geography to draw, e.g. 'us:county:34013'. children_level: draw everything at that level inside it instead, e.g. every 'precinct' in a county or state, every 'county' in a state, every 'polling_division' in a riding, or every 'precinct' overlapping a congressional district (any share; use related_geographies for shares). detail: 'high' (~10 m), 'medium' (~50 m, default) or 'low' (~200 m). Neighbouring shapes from the same source share identical edges at every detail level. clip_to_land: trim open water (ocean, bays, Great Lakes) using the state/province shoreline outline (default true; inland lakes are not trimmed; shorelines are generalized to ~1:500k, widened ~200 m so land isn't cut); false gives legal extents. include_districts: add each feature's congressional / state senate / state house district holding the largest share of its population. Feature properties: id, level, code, name, parent_id, region, population (2020 Census for precincts and towns, latest estimate for counties and states), vintage and source_id (2020 Census VTDs have source_id 'us-census-vtd-2020'; current precincts don't), shape_source. Small results come back inline as `geojson`. Larger ones are not returned inline (they'd flood the conversation): the hosted service returns a short-lived `download_url` (fetch it with curl into your project); a local server writes the file to its own export folder and returns `file` (copy it into your project). Page big selections with offset/limit (max 5000 features).
