A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

calculate_curvatureread-only | Calculates how much of a distant target the Earth's curvature hides, from the surface distance, the observer's eye height, the target's height and an assumed refraction coefficient. Returns the hidden and visible height, the tangent-plane drop, the horizon distance and dip, the maximum mutual sight-line range and the midpoint bulge on a smooth sphere of radius 6,371.0084 km. |
compare_flat_map_distanceread-only | Compares the distance between two cities on a north-polar flat-Earth map with their great-circle distance over a sphere. Returns both distances and the factor by which the map stretches or shrinks the pair. |
compare_true_sizeread-only | Shows how much a Mercator map distorts a country's area, from its real area and the latitude it is drawn at. Returns the real area, the area multiplier at the country's own latitude and at a chosen latitude, and the size it appears at each. Covers the nine countries and regions in the website's size table. |
find_claimsread-only | Searches the website's tested claims and flat-earth investigations, or returns one by id. Each result gives the claim, the verdict, the key evidence and the link to its page; an empty query lists all of them. |
get_daylight_hoursread-only | Calculates the length of daylight at a place on a date, with sunrise and sunset in UTC, for the UTC day from midnight to midnight. A place is one of the website's 20 cities or a latitude with an optional longitude. |
get_flight_distanceread-only | Calculates the great-circle distance between two places in kilometres, miles and nautical miles, with the initial and final compass bearings. Each end is one of the website's 20 cities or a latitude and longitude. |
get_horizon_distanceread-only | Gives the distance to the horizon from an eye height above a smooth sphere, and how far a taller object such as a mast stays in straight sight. Returns the observer's horizon distance, the range added by the target height and the maximum shared sightline. |
get_sun_positionread-only | Calculates the Sun's altitude and compass bearing at a place, date and UTC time, with the shadow of a 1 m upright and the day's sunrise and sunset in UTC. A place is one of the website's 20 cities or a latitude and longitude; without a date and time the result is for the current moment. |
