## 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 aisa-mpp-data-apis-central-bank-interest-rates-snapshot-d38d2b7e
```

Example prompt: What's the current policy rate for the Federal Reserve? Pull the latest snapshot from the central bank interest rates data.

## When to prefer this

Use this endpoint when you need the current, most recently published policy rate for one or more central banks in a single synchronous call. It is ideal for real-time financial applications, macro dashboards, or enriching models with current monetary conditions. Prefer this over the history endpoint when you only need the latest snapshot, not time-series data.

## Known failure modes

- Invalid or unrecognized bank code returns empty results or an error
- Bank code not in covered list — use /macro/interest-rates/banks to confirm available codes
- Rate data may lag if a central bank has not yet published its latest decision
- Network or service unavailability returns a non-200 HTTP error

## How this service works

The newest published policy rate of every central bank we cover, one row per bank with the date it is in effect. Pass bank to get one bank only.

<!-- aisa-pricing:start -->
Published reference price: $0.02 USD per successful request. Account-specific pricing and final settlement may differ.
<!-- aisa-pricing:end -->

## Output

An array of interest rate objects, each containing the bank symbol, bank name, the calendar date the rate is in effect (YYYY-MM-DD), and the policy rate as a percentage. For the Federal Reserve, the rate is the midpoint of the target range. If a bank code is specified, only one row is returned.
