Maidenhead Locator API
Convert between latitude/longitude and the Maidenhead Locator System — the grid-square "QTH locator" (like JN58td or IO91wm) used by amateur radio, APRS and contesting to describe a position compactly. The encode endpoint turns a latitude and longitude into a locator at 4-, 6-, 8- or 10-character precision. The decode endpoint turns a locator back into the centre coordinates, the south-west corner and the size of the grid square. The distance endpoint gives the great-circle distance (kilometres and miles) and bearing between the centres of two locators — the classic "how far and which way is that station". Everything is computed locally and deterministically, so it is instant and private. Ideal for amateur-radio and APRS tools, contest logging, antenna aiming, and grid-based mapping. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the Maidenhead system; for Plus Codes, MGRS, UTM and DMS use a geo-convert API and for precise geodesic distance use a geodesy API.

Antenna Length API
Antenna length maths as an API, computed locally and deterministically. The dipole endpoint gives the total and per-leg length of a half-wave dipole for a frequency, in metres, feet, inches and centimetres, applying a velocity factor (about 0.95 for wire) and also reporting the classic 468 ÷ f(MHz) feet rule of thumb. The quarterwave endpoint gives the element length of a quarter-wave vertical or monopole, with the 234 ÷ f(MHz) rule. The element endpoint computes the length of an element at any fraction of a wavelength — full-wave, half-wave, quarter-wave, fifth-wave, five-eighths or a custom fraction. Frequencies accept Hz, kHz, MHz and GHz, and the velocity factor is configurable. Everything is computed locally and deterministically, so it is instant and private. These are starting lengths: real antennas need trimming and tuning for the lowest SWR, as end effects and surroundings shift the resonant length. Ideal for amateur-radio and RF tools, antenna and IoT design, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is antenna geometry; for general wavelength, frequency and photon energy use a wavelength API.

OpenStreetMap Community API
Live OpenStreetMap Community- und Beitragsdaten als API – die Personen und Bearbeitungen hinter der kollaborativen freien Weltkarte, bereitgestellt von der offiziellen OSM API. Rufen Sie jeden Mapper anhand seiner Benutzer-ID für sein Profil ab (Anzeigename, Kontolaufzeit, gesamte Changesets und GPS-Traces, Rollen), ziehen Sie die letzten Changesets eines Benutzers – jede Bearbeitungsgruppe mit ihrem Kommentar, dem verwendeten Editor und wie viele Kartenfunktionen erstellt, geändert oder gelöscht wurden – oder lesen Sie die offenen und gelösten Kartennotizen, die Community-Feedback-Pins, innerhalb eines geografischen Begrenzungsrahmens. Die OSM-Contributor-und-Edits-Schicht für Kartierungs-, Community- und Dashboard-Apps. Live, kein Key. Abgrenzung zu Geocoding-, Routing- und Kartenkachel-APIs, die lediglich OpenStreetMap-Daten konsumieren – dies ist die OSM-Community- und Bearbeitungsaktivität selbst.

Meteorites API
NASA's catalogue of 45,000+ meteorites recovered on Earth as an API. For each meteorite: its name, NASA id, classification (recclass, e.g. L5, Iron), mass in grams, whether it was seen to fall or simply found, the year, and the latitude/longitude where it was recovered. Look one up by name or id, find the meteorites NEAR any coordinate (great-circle distance), rank by mass or year, list a classification or year, or search. Great for space, education, mapping and museum apps. Distinct from asteroids and close-approach data — these are rocks already on the ground.

Time Zones API
Jede IANA-Zeitzone mit ihren Koordinaten und dem Land, in Echtzeit angereichert mit dem aktuellen UTC-Offset, der Abkürzung, dem DST-Status und der Ortszeit (berechnet aus der systemischen ICU-Zeitzonendatenbank – immer aktuell, kein Key). Suchen Sie eine Zone nach Namen, listen Sie alle Zonen für ein Land auf, durchsuchen Sie Zonen nach Namen oder finden Sie die nächsten IANA-Zonen zu einem beliebigen Breiten-/Längengrad. 418 Zonen in 247 Ländern/Territorien. Ideal für Terminplanung, Kalender, Logistik, Geo-Apps und jede Funktion, die einen Ort oder eine Koordinate der richtigen Zeitzone und aktuellen Ortszeit zuordnen muss.
