Can I Use API

salutare 4,682 Abbonati

Browser-feature compatibility data as an API — the "Can I Use" support tables for over 550 web platform features across 19 browsers (Chrome, Edge, Firefox, Safari, iOS Safari, Samsung Internet, Opera, IE and more). Look up any feature (flexbox, css-grid, webp, fetch, websockets, …) for its full support matrix: per-browser current support, the first version that shipped full support, partial/prefixed/disabled flags and notes, the spec status, categories, keywords, global usage share and reference links. Ask a single feature×browser question, list or filter features by category, search features by keyword, and get the browser/agent list with version histories and the category/status legend. Backed by the public caniuse-db dataset (refreshed every 12 hours); query results are computed live. 7 endpoints. Built for build tooling, polyfill decisions, compatibility dashboards, linters and documentation. No upstream key.

Sauna Heater API

Sauna-Heizer-Berechnungen als API, lokal und deterministisch berechnet – die Heizleistung, Steinmasse und elektrischen Werte, die ein Saunabauer, Installateur oder Wellnesshändler für eine Kabine dimensioniert. Der Heizgrößen-Endpoint gibt die Leistung: etwa 1 kW pro 1,3 m³ gut isolierter Kabine (Raumvolumen ÷ 1,3), wobei kalte Oberflächen, die der Heizer ebenfalls erwärmen muss – eine Glastür oder -wand, nackter Stein, Fliesen oder ungedämmtes Holz – etwa 1,2 m³ äquivalentes Volumen pro Quadratmeter hinzufügen, sodass ein 10 m³ Raum mit einer 2 m² Glastür etwa einen 10 kW Heizer benötigt, aufgerundet auf die nächste Standardgröße. Der Steine-Endpoint gibt die empfohlene Saunasteinmasse, etwa 10–20 kg pro kW (mehr Steine für einen weicheren, dampfigen Löyly, weniger für eine schnellere Aufheizzeit), mit einem Hinweis, richtige Peridotit/Olivin-Steine locker gestapelt zu verwenden. Der Elektrik-Endpoint gibt den Strom an, den der Widerstandsheizer zieht – Leistung ÷ Spannung für einphasig oder ÷ (√3 × Spannung) für dreiphasig, da die meisten Heizer über ~4 kW dreiphasig angeschlossen werden, um den Strom pro Leitung und Kabelquerschnitt gering zu halten – zur Dimensionierung des Schutzschalters und des dedizierten FI-geschützten Stromkreises. Alles wird lokal und deterministisch berechnet, daher ist es sofort und privat. Ideal für Sauna- und Wellnesshändler, Heimwerker- und DIY-Tools sowie HLK-/Elektro-Schätzungs-Apps. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Schätzungen – folgen Sie der Tabelle des Heizerherstellers und den örtlichen Elektrovorschriften. 3 Compute-Endpoints. Für Dampfkesselberechnungen verwenden Sie eine Boiler-API; für Raumwärmeverlust eine U-Wert-API.

Hot Air Balloon Lift API

Hot-air-balloon lift maths as an API, computed locally and deterministically — the thermal-lift, envelope-temperature and air-density numbers a balloon pilot, designer or physics teacher works a flight out with. The lift endpoint gives the buoyant lift from heating the air: gross lift = envelope volume × (outside air density − inside air density), the densities from the ideal-gas law — a 2,500 m³ envelope at 100 °C on a 15 °C day lifts about 698 kg gross, from which you subtract the envelope, basket, burner and fuel for the payload, and the hotter the air and colder the day the more it lifts. The required-temp endpoint inverts it: to carry a target lift the inside air must reach a particular density and so a particular temperature, with a check that it stays under the ~120 °C that nylon envelopes can take — the everyday pre-flight question of whether the balloon can lift today's crew and fuel. The air-density endpoint gives the moist-air density ρ = (P − 0.378·Pv) ÷ (R·T), and explains the counter-intuitive fact that humid air is LESS dense than dry air, slightly cutting the lift. Everything is computed locally and deterministically, so it is instant and private. Ideal for ballooning and aviation tools, STEM and physics-education apps, and buoyancy calculators. Pure local computation — no key, no third-party service, instant. Idealised dry-lift model. 3 compute endpoints. For Archimedes flotation in water use a buoyancy API; for party-balloon helium lift a balloon API.

Water Hammer API

Water-hammer (hydraulic-transient) maths as an API, computed locally and deterministically — the surge-pressure, wave-speed and valve-timing numbers a piping or plumbing engineer guards a system with. The surge endpoint applies the Joukowsky equation Δp = ρ · a · Δv: a sudden stop of the flow spikes the pressure by the fluid density × the pressure-wave speed × the velocity change — stopping 2 m/s of water at a ≈ 1200 m/s adds about 24 bar (348 psi), far above the line pressure, which is what bangs the pipes and can split fittings. The wave-speed endpoint gives that pressure-wave speed: a = √(K/ρ) in a rigid pipe (≈ 1,480 m/s for water), slowed in a real elastic pipe to √(K/ρ) ÷ √(1 + (K·D)/(E·t)) — a thin or plastic pipe gives a lower wave speed and a gentler surge, which is why PVC tolerates hammer better than steel. The critical-time endpoint gives 2L/a, the round-trip time of the wave: close a valve faster than this and you get the full Joukowsky surge, slower and the returning relief wave eats into it, so sizing closure times (or fitting a surge tank or air chamber) above the critical time is the standard cure. Everything is computed locally and deterministically, so it is instant and private. Ideal for piping- and plumbing-design tools, pump-station and pipeline-surge analysis, and hydraulic-engineering utilities. Pure local computation — no key, no third-party service, instant. Idealised single-pipe transient. 3 compute endpoints. For steady pipe pressure drop use a Darcy API; for pump head and affinity a pump API.

HVAC Air-Side Load API

HVAC air-side heat maths as an API, computed locally and deterministically with the classic standard-air factors — the sensible, latent and airflow numbers a mechanical engineer or HVAC technician sizes ducts and equipment with. The sensible endpoint gives the sensible heat an airflow carries to change temperature: Qs = 1.08 × CFM × ΔT (dry-bulb difference), where the 1.08 bundles standard-air density and specific heat — 2,000 CFM across a 20 °F difference is 43,200 BTU/hr, 3.6 tons — with the result in BTU/hr, tons and kW. The latent endpoint gives the latent (moisture) heat: Ql = 0.68 × CFM × ΔW, where ΔW is the humidity-ratio difference in grains of water per pound of dry air, the dehumidification part of a cooling load that runs high in humid climates and from people and cooking, and why air conditioners are sized on total, not just temperature. The airflow endpoint inverts the sensible relation: CFM = sensible load ÷ (1.08 × ΔT), the supply air needed at a chosen supply-to-room temperature difference (comfort cooling runs ~18–22 °F below room), the number that sets fan and duct size — sanity-checked against ~400 CFM per ton. Everything is computed locally and deterministically, so it is instant and private. Ideal for HVAC-design and load-calc tools, mechanical-estimating and commissioning utilities, and building-engineering apps. Pure local computation — no key, no third-party service, instant. Standard-air factors — adjust for altitude. 3 compute endpoints. For room rule-of-thumb sizing use an HVAC API; for moist-air properties a psychrometric API; for duct sizing a ductwork API.
