      "description": "US market-liquidity and financial-conditions macro read, made agent-callable. One x402 call (no parameters) returns net liquidity — the Fed balance sheet minus overnight reverse repo minus the Treasury General Account, the widely-watched proxy for the dollar liquidity behind risk assets — and its 4-week trend (EXPANDING / NEUTRAL / CONTRACTING), plus financial conditions from the Chicago Fed NFCI (LOOSE / NEUTRAL / TIGHT), the high-yield credit spread, the 10y-2y yield curve, and a combined regime read (risk-on tailwind / mixed / risk-off headwind). The 'is the tide coming in or going out' signal that sits behind every risk asset, served pay-per-call. $0.05 in USDC on Base via x402. Source: FRED / Federal Reserve (free/public).
