## 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 financial-data-x402-money-supply-a926b720
```

Example prompt: What's the current M1 and M2 money supply in the US, and how much has M2 changed year-over-year?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time US money supply and credit data (M1, M2, C&I loans) without managing API keys or subscriptions. It is ideal for AI agents that need lightweight per-call access to macroeconomic monetary aggregates, especially in crypto-native or x402-enabled payment environments. Prefer it over Bloomberg or FRED direct integrations when simplicity and micropayment-based access (USDC on Base/Solana) are a priority.

## Known failure modes

- Upstream FRED data unavailable — series may appear in failed_series array
- Stale data if Federal Reserve hasn't published latest release — dates in response will reflect actual publication lag
- Payment failure if USDC balance insufficient on Base or Solana — 402 response returned before data
- Network timeout if x402 facilitator is unreachable

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.

## Output

A JSON object containing the as-of date for the response, M1 money stock in billions with its latest date, M2 money stock in billions with its latest date plus year-over-year percent change, commercial and industrial loans in billions with year-over-year percent change, and a list of any failed data series.
