  35. 91asistent-crypto.vercel.app/api/x402/data/macro-ratesThe macro regime that drives crypto, as signals rather than raw levels: the 2s10s yield curve spread with its direction and an inverted flag, Fed funds, 2Y and 10Y yields, CPI year-over-year, the broad dollar index, VIX and M2 — each with its previous reading, so direction comes free. The slope of the curve, not the level of any single yield, is the liquidity signal: re-steepening out of inversion marks the easing that risk assets price first.$0.01 Base465 ms2 payers93% up
  36. 91asistent-crypto.vercel.app/api/x402/data/market-historyWhether the current reading is actually high or low, from a series captured every ~10 minutes: funding, open interest, Fear & Greed and BTC dominance, each as current, median, min, max and percentile over the window. A funding rate of 0.006% means nothing on its own; at the 89th percentile of the last 24 hours it means something.

  37. 91asistent-crypto.vercel.app/api/x402/data/implied-volatilityWhat 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.$0.02 Base451 ms2 payers93% up
  38. 91asistent-crypto.vercel.app/api/x402/data/briefThe 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.
