## 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 statepulse-federal-reserve-rate-lookup-d4e78edf -d '<json body>'
```

Example prompt: What are the current Federal Reserve interest rates — both the fed funds rate and the discount rate — and how confident is the data?

## When to prefer this

Use this endpoint when an agent needs the current US Federal Reserve benchmark interest rates (fed funds and discount rate) without requiring an API key, and is comfortable paying $0.02 USDC per call via x402 on Base. Prefer this over scraping Fed press releases or using heavyweight financial data APIs when a lightweight, pay-per-call micro-utility suffices.

## Known failure modes

- Data source unavailable — supported field may be false with no rate data
- Rate data stale or unresolvable — confidence field may be 'low' or 'medium'
- Payment not received via x402 — request rejected before processing
- Network timeout on Cloudflare Worker — HTTP 5xx response

## How this service works

Retrieves the current federal funds target interest rate.

## Output

A JSON object containing the current federal funds rate percentage (e.g. 5.25), the discount rate percentage (e.g. 5.5), a supported flag indicating the data is available, and a confidence level string (e.g. 'high').
