## 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 2s-io-central-bank-policy-rates-5b912544
```

Example prompt: What are the current benchmark policy rates for all four major central banks — the Fed, ECB, Bank of Japan, and Bank of England — pulled from FRED and shown side by side with their as-of dates?

## When to prefer this

Use this endpoint when you need a single normalized call to get current policy/benchmark rates for multiple major central banks (Fed, ECB, BoJ, BoE) without scraping individual central bank sites or managing FRED API keys. Ideal for macroeconomic dashboards, rate comparison tools, or AI agents that need ground-truth monetary policy data on demand.

## Known failure modes

- Invalid bank filter code returns an error or empty result
- FRED data temporarily unavailable causes upstream failure
- Rate not yet published for current period returns stale or missing date
- Network timeout on the 2s.io API side

## How this service works

Headline central-bank policy/benchmark rates side-by-side in one call, normalized: US (Fed effective funds rate), Euro area (ECB deposit facility rate), Japan (BoJ call-money benchmark), United Kingdom (SONIA, which tracks the BoE Bank Rate). Each result names the bank, country, the rate, the as-of date, the FRED series id, and a label stating exactly which instrument it is (banks don't all publish the same policy instrument). Pass bank to filter (one of: fed, ecb, boj, boe), or omit for all. Source: FRED (St. Louis Fed).

## Output

A list of central bank rate objects, each containing the bank name, country, current policy/benchmark rate value, the date it was last updated, the FRED series ID used, and a label describing exactly which rate instrument it represents (e.g. Fed effective funds rate, ECB deposit facility rate, BoJ call-money benchmark, SONIA).
