## 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 x402stock-fed-funds-rate-endpoint-6ce48682
```

Example prompt: What is the current US federal funds rate, and can you pull the historical rate data from the last two years so I can see how the Fed has moved rates over that period?

## When to prefer this

Choose this endpoint when you need authoritative US Federal Reserve federal funds rate data — current or historical — without managing API keys or subscriptions. Ideal for AI agents that require autonomous macro data access with transparent per-call USDC micropayments. Prefer this over general financial data APIs when you want no-account pay-per-use access to Fed policy data specifically.

## Known failure modes

- Invalid properties filter syntax returns 400 error
- Payment not received or insufficient USDC balance results in 402 Payment Required
- Network timeout if upstream x402stock API is unavailable
- Rate limiting if request volume exceeds plan thresholds
- Missing or malformed request body returns validation error

## How this service works

The effective federal funds rate — the Fed's benchmark policy rate that anchors every other US interest rate — as a monthly average in percent, with the latest value, prior month, month-over-month and year-over-year change, and recent history. No ticker needed. The rate every rate-sensitive analysis starts from. Sourced from the St. Louis Fed (FRED). From x402stock

## Output

Returns current and historical US Federal Reserve federal funds rate data, including the target rate or effective rate values, dates, and any relevant Fed policy context. Delivered as structured JSON suitable for macro analysis, charting, or financial reporting.
