## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability liquiditypulse-cea974b2
```

Example prompt: What's the current US liquidity regime — is the Fed net liquidity expanding or contracting, and are financial conditions loose or tight right now?

## When to prefer this

Choose this endpoint when you need a single no-parameter call to get a comprehensive, pre-computed US macro liquidity snapshot combining Fed balance sheet dynamics, NFCI, credit spreads, and yield curve into a unified regime signal. Prefer it over assembling individual FRED series yourself when you want a pay-per-call, agent-ready format with built-in regime classification. It pairs naturally with positioning signals (COT, funding rates) and MacroPulse for a full macro overlay.

## Known failure modes

- FRED data source unavailable or delayed — may return stale or error response
- Upstream Federal Reserve data publication lag may mean readings are not real-time intraday
- Network or payment gateway failure returns HTTP 402 or 5xx with no payload
- ON RRP or TGA data temporarily missing may produce null component values

## How this service works

US market-liquidity & financial-conditions macro signal (no params)

## Output

A JSON object containing: net liquidity in USD billions (Fed balance sheet minus ON RRP minus TGA), 4-week change in USD billions and percent, a liquidity signal enum (EXPANDING/NEUTRAL/CONTRACTING), component breakdowns (bank reserves, Fed balance sheet, ON RRP, TGA in USD bn), Chicago Fed NFCI score and financial conditions enum (LOOSE/NEUTRAL/TIGHT), 10y-2y yield curve spread, high-yield credit spread percent, and a combined regime label (e.g. 'Mixed') with a plain-English interpretation string.

 "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). Sibling of MacroPulse; pairs with the positioning cluster (COT, FundingRates)."
