per call · USD Coin on Base
The answer, not the inputs. One call returns a stance for the coin — risk-on, risk-off, fragile or neutral — built from funding and open interest percentiles, sentiment, options implied volatility, the macro regime and what it costs to execute at your size. Every driver comes back with its number and its reading, plus the conditions that would invalidate the call. The rules are deterministic: the same market gives the same verdict.

More from Asistent Crypto & similar services
Asistent Crypto · Data Fear Greed
asistent-crypto.vercel.app
Crypto Fear & Greed Index: current and previous value with classification, plus recent history. A contrarian input — extreme fear has historically marked accumulation zones and extreme greed distribution zones — but it is a filter, never a trigger on its own. Pair it with funding to separate real capitulation from a crowded short.
Asistent Crypto · Data Implied Volatility
asistent-crypto.vercel.app
What the options market expects price to do, not what leverage is doing: the 30-day implied volatility index for BTC and ETH, with its percentile over the last month and the expected move in percent over 1, 7 and 30 days. Funding tells you who is crowded; this tells you how much movement is already priced in — and whether hedging is cheap or expensive relative to where it has been.
Asistent Crypto · Data Funding BY Venue
asistent-crypto.vercel.app
Funding rate and open interest for one coin, broken down venue by venue across Binance, Bybit, OKX and Hyperliquid, using each venue's largest-open-interest perpetual. Use it when venue divergence matters: one venue far more positive or negative than the rest is localised positioning, not market consensus — the setup that precedes a squeeze on that venue alone. Returns per-venue rows plus average funding, total open interest and the spread.
