## 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 vextorium-central-bank-policy-interest-rates-74f4aedc -d '<json body>'
```

Example prompt: Show me the current policy interest rate ranking across all major central banks from BIS data, and then pull the monthly rate history for Turkey for the last 24 months.

## When to prefer this

Use this endpoint when you need authoritative, BIS-sourced central bank policy rate data — either a ranked cross-country snapshot or a single country's rate history including every hike and cut. Prefer this over general financial data APIs when you specifically need official monetary policy rates (not market rates or bond yields) for up to ~40 central banks including the Fed, ECB, BoE, BoJ, Banxico, and BCB.

## Known failure modes

- Invalid or unsupported country ISO code returns empty or error response
- Requesting a country not covered by BIS data yields no results
- Omitting required 'type', 'method', and 'bodyType' fields causes a 400-level error
- Requesting more months than available historical data silently truncates the series
- Network or upstream BIS data unavailability causes timeout or 5xx error

## How this service works

Policy interest rate of about 40 central banks (Fed, ECB, BoE, BoJ, Banxico, BCB...): latest rate and date as a ranking, or one country's monthly history with every hike and cut. Bank for International Settlements data.

## Output

Returns a JSON object with a source label ('Bank for International Settlements'), the total number of central banks covered, and either: (a) a ranked array of all central banks each with country ISO code, country name, latest rate percentage, and rate date; or (b) a monthly time series for a single country showing each rate change date and corresponding rate percentage.
