## How this service works

US net liquidity (Fed balance sheet minus Treasury General Account minus reverse repo) as a 0–100 percentile with its label and 4-week trend, broken into its FRED components (WALCL, TGA, RRP, M2) plus ~52 weeks of history. A macro-liquidity gauge for risk appetite. Complements the /api/v1/fed-funds and other FRED macro endpoints. From x402stock, a market & economic data API (x402, USDC).

## Output

Returns the current Fear & Greed index score and liquidity conditions for US markets, typically including a numeric score, a sentiment label (e.g. Extreme Fear, Fear, Neutral, Greed, Extreme Greed), and associated liquidity metrics. Costs $0.01 USDC per call, deducted via x402 payment protocol.
