Tank Volume API

salutare 4,465 Abbonati

Tank volume and fill-level maths as an API, computed locally and deterministically. The volume endpoint gives the total capacity — in litres, US gallons and cubic metres — of a vertical cylinder, horizontal cylinder, rectangular tank, sphere or capsule, from its dimensions in metres, centimetres, millimetres, feet or inches. The fill endpoint computes the volume of liquid and the percent full at a given fill depth, using the exact geometry for each shape — including the circular-segment formula for a horizontal cylinder (where the level is famously non-linear) and the spherical-cap formula for a sphere. The level endpoint is the inverse "dipstick" calculation: it finds the depth that corresponds to a target volume or a target percentage, solving the segment geometry by bisection. Everything is computed locally and deterministically, so it is instant and private. Ideal for fuel, water, oil and chemical tank monitoring, agriculture and irrigation, process and industrial tooling, and tank-gauging and dipstick apps. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank-gauging geometry; for swimming-pool volume and chemical dosing use a pool API, and for plain unit conversion use a unit-conversion API.

OBV & Volume Screener (Multi-Asset) API — oanor API marketplace

OBV & Volume Screener (Multi-Asset) API

Welche Märkte befinden sich in Akkumulation oder Distribution und wo das Volumen steigt, live berechnet aus Yahoo Finance (kein API-Key, nichts gespeichert). Der Preis sagt Ihnen, was passiert; das Volumen sagt Ihnen, ob Sie es glauben sollen. Der On-Balance Volume addiert das Tagesvolumen, wenn ein Markt steigt, und subtrahiert es, wenn er fällt, sodass ein steigender OBV bedeutet, dass Käufer die Kontrolle haben (Akkumulation) und ein fallender OBV, dass Verkäufer die Kontrolle haben (Distribution) – und eine Divergenz zwischen OBV und Preis ist eine frühe Warnung vor einer Trendwende. Ein Volumenanstieg – das heutige Volumen deutlich über dem jüngsten Durchschnitt – signalisiert Überzeugung hinter einer Bewegung. Für ein assetübergreifendes, sektorübergreifendes Universum – Aktienindizes und -sektoren, Gold, Öl, Rohstoffe, Anleihen und Krypto – berechnet dies den OBV-Trend jedes Assets über den letzten Monat, sein aktuelles Volumen im Vergleich zum 20-Tage-Durchschnitt und kennzeichnet es als Akkumulation, Distribution oder neutral. Der Screener-Endpunkt gibt die Märkte unter Akkumulation und Distribution sowie die mit einem Volumenanstieg zurück. Der Asset-Endpunkt gibt eine OBV/Volumen-Karte für einen Markt zurück. Der Universe-Endpunkt listet auf, was abgedeckt wird. Der assetübergreifende Volumen-/OBV-Screener-Schnitt – unterscheidet sich von der Bring-Your-Own-Candle-Volumenindikator-API und der Krypto-Volumenprofil-API; er fügt die Volumendimension hinzu, die die rein preisbasierten Screener vermissen lassen.

 Volume Indicators API — oanor API marketplace

Volume Indicators API

Live volume-based technical indicators that traders run to confirm a move with the volume behind it, computed on demand from the OHLCV candles you pass in — no key, no cache, nothing stored. The mfi endpoint returns the Money Flow Index, a volume-weighted version of RSI that swings from 0 to 100, with an overbought reading above 80 and oversold below 20. The obv endpoint returns On-Balance Volume, the running total that adds a candle's volume on an up close and subtracts it on a down close, together with whether it is rising or falling — rising OBV confirms buying pressure. The cmf endpoint returns the Chaikin Money Flow, which sums money-flow volume over the lookback to show whether buyers or sellers are in control. These indicators all need the volume of each candle, which makes them a fundamentally different tool from price-only indicators like RSI, MACD, Stochastic and ADX: they answer whether volume is confirming the price move or diverging from it. Works for any market — forex, stocks, crypto or commodities — because you supply the candles with volume. Computed locally and deterministically, so it is instant and private. Ideal for trading bots, divergence screeners, breakout confirmation and trading dashboards. Candles are open:high:low:close:volume. Live, nothing stored. 3 compute endpoints. For price-only indicators use a technical-indicators, oscillators or trend-indicators API.

 Crypto Exchanges API — oanor API marketplace

Crypto Exchanges API

Live rankings and comparison of crypto exchanges, served from the public CoinPaprika feed — no key, nothing cached. Rank every crypto exchange by adjusted 24h volume with its 7d/30d volume, number of markets and currencies and confidence score; pull one exchange's full profile (volumes, market count, website and social links, status); list an exchange's trading pairs with price and 24h volume; and search exchanges by name. A cross-exchange comparison layer, distinct from single-exchange ticker feeds and whole-market price feeds — it answers which venues are biggest and what they trade. Volumes in USD; adjusted = wash-trade-filtered.

 Crypto Volume API — oanor API marketplace

Crypto Volume API

Live most-traded crypto pairs by 24-hour spot volume as an API, powered by Binance. It ranks the trading pairs by their 24-hour quote volume — where the real liquidity and activity is right now — with each pair's last price, daily change, 24-hour high and low, base and quote volume, and the number of trades. Rank by any quote currency (USDT, BTC, ETH, USDC), or look a single pair up for its full 24-hour stats. The spot-volume and market-activity leaderboard for trading, screening and dashboard apps. Live, no key, no cache. Distinct from price-change movers and from DEX-volume APIs — this is centralised-exchange spot trading volume.
