Black Hole Physics API
Black-hole general-relativity maths as an API, computed locally and deterministically. The radius endpoint computes the Schwarzschild radius r_s = 2GM/c² — the event horizon of a non-rotating black hole — from a mass given in kilograms or solar masses, together with the photon sphere at 1.5·r_s and the innermost stable circular orbit (ISCO) at 3·r_s; the Sun would have an event horizon about 2.95 km across and the Earth about 9 mm. The time-dilation endpoint computes the gravitational time-dilation factor √(1 − r_s/r) at a distance r from a mass — a clock deep in a gravity well ticks slower than a far-away clock, and at the horizon time appears to stop. The hawking endpoint computes the Hawking temperature T = ħc³/(8πGMk_B), which is higher for smaller black holes, and the evaporation time, which scales as the cube of the mass — a solar-mass black hole would take about 10^67 years to evaporate. Masses are in kilograms or solar masses and distances in metres, using G, c, ħ and the Boltzmann constant. Everything is computed locally and deterministically, so it is instant and private. Ideal for astrophysics, cosmology, science-communication, simulation and education app developers, black-hole and relativity tools, and physics teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is general-relativity black-hole physics; for special relativity (Lorentz factor, E=mc²) use a relativity API.

Tidal Forces API
Tidal-physics and gravitational-dominance astrophysics as an API, computed locally and deterministically. The tidal-force endpoint computes the tidal (differential) acceleration that stretches a body, a = 2·G·M·r/d³, from the primary mass, the radius (half-size) of the affected body and the centre-to-centre distance — and the force if a body mass is given; tidal effects fall off as the inverse cube of distance, far faster than gravity's inverse square, which is why they matter only close in. The roche-limit endpoint computes the Roche limit, the distance inside which tidal forces tear a satellite apart, for both rigid bodies, d = R·(2·ρM/ρm)^(1/3), and fluid bodies, d = 2.44·R·(ρM/ρm)^(1/3), from the primary radius and the two densities — Saturn's rings sit inside its Roche limit. The hill-sphere endpoint computes the Hill-sphere radius, r_H ≈ a·(1−e)·(m/3M)^(1/3), the region where a body's own gravity dominates so it can keep moons, from the orbital distance, eccentricity and the two masses. Masses are in kilograms, distances and radii in metres and densities in kg/m³, with G = 6.674×10⁻¹¹. Everything is computed locally and deterministically, so it is instant and private. Ideal for astronomy, astrophysics, planetary-science, simulation and education app developers, ring-system and moon-stability tools, and physics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tidal and gravitational-dominance physics; for Newtonian gravity use a gravitation API and for orbital periods an orbital-mechanics API.

API de Magnitud y Distancia Estelar
Matemáticas de magnitud y distancia estelar como una API, calculadas local y determinísticamente. El endpoint de magnitud aplica el módulo de distancia, m − M = 5·log₁₀(d/pc) − 5 — proporciona dos de los siguientes: magnitud aparente m, magnitud absoluta M y distancia, y devuelve el tercero, con la distancia en pársecs, años luz y unidades astronómicas (la magnitud absoluta es la magnitud aparente que tendría una estrella a 10 pársecs). El endpoint de flujo aplica la relación de Pogson para convertir una diferencia de magnitud en una relación de brillo, F₁/F₂ = 10^(0.4·(m₂ − m₁)), donde cinco magnitudes equivalen exactamente a un cambio de cien veces en brillo — a partir de dos magnitudes, una diferencia de magnitud o una relación. El endpoint de paralaje convierte un ángulo de paralaje en una distancia, d(pc) = 1 ÷ p(arcosegundos), y viceversa, el método geométrico detrás del propio pársec. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de educación astronómica, planetarios, observación de estrellas y ciencia, herramientas de observación y astrofísica, y enseñanza STEM. Cálculo puramente local — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es magnitud y distancia estelar; para mecánica orbital usa una API orbital y para distancias de círculo máximo en la Tierra una API de geo-distancia.

Programming Languages API
The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

MIME Types API
Die kanonische MIME-/Medientyp-Datenbank (die jshttp mime-db, die von Express und dem Großteil des Node-Ökosystems verwendet wird: IANA + Apache + nginx), aus dem Speicher bereitgestellt — kein Key. Lösen Sie einen Medientyp in seine Dateierweiterungen, Zeichensatz und Komprimierbarkeit auf; suchen Sie den/die Medientyp(en) für eine Dateierweiterung (z. B. png → image/png); und listen oder durchsuchen Sie Typen nach Quelle. 2.600+ Medientypen, 1.000+ mit Dateierweiterungen. Schlankes, vorhersagbares JSON. Ideal für Upload-Validierung, Content-Type-Auflösung, Dateityperkennung, Download-Handler und Entwicklerwerkzeuge.
