Volume Indicators API

degraded 4,798 Subscribers

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

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

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.

DEX Volume API

Live decentralised-exchange trading volume across the whole crypto ecosystem as an API, streamed from the DefiLlama DEX feed. For thousands of DEX protocols: the trading volume over the last 24 hours, 7 days and 30 days, the day/week/month change, the chains they run on, and each one's share of the total DEX market. Rank the busiest DEXes, drill into a single one, see how trading volume is split across chains, or read the market-wide total. Built for crypto, trading and dashboard apps. Live, no key. Distinct from TVL, fees, yield and stablecoin APIs — this is the on-chain trading-activity surface.

Aquarium Calculator API

Aquarium maths as an API, computed locally and deterministically. The volume endpoint computes a tank's water volume — in US and UK gallons and litres — for a rectangular, cube, cylinder, hexagonal or bow-front tank from its dimensions (inches by default, or centimetres, millimetres and metres), and applies a fill factor (default 0.9) for substrate, decoration and freeboard to give a realistic net volume. The stocking endpoint gives a rough stocking load from the tank volume and the total length of fish using the classic inch-per-gallon guideline, reporting the maximum recommended inches and how heavily stocked the tank is. The waterchange endpoint computes the water-change volume for a percentage, with an optional dechlorinator dose. Everything is computed locally and deterministically, so it is instant and private. Stocking is a rough beginner guideline only — real stocking depends on the species, filtration and bioload. Ideal for aquarium and fishkeeping apps, pet-shop and hobbyist tools, and tank-setup planners. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is aquarium maths; for swimming-pool volume and chemical dosing use a pool API and for storage-tank gauging use a tank API.
