How this service works
The daily policy rate of one central bank: one row per calendar day, newest first, 10 rows per page. A rate change appears on the first day the new rate is in effect. For the Federal Reserve the rate is the midpoint of the target range. <!-- 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 objects each containing the bank symbol, central bank name, calendar date, and the policy rate in percent for that day. For the Federal Reserve, the rate is the midpoint of the target range. Results are ordered newest-first, with up to 10 rows per page and a next_page_url for pagination when more data exists.
Example use cases
Tracking Fed rate hike cycle
“Can you pull the Federal Reserve's daily interest rate history from January 2022 through December 2023? I want to see exactly when the rate changes happened during the hiking cycle.”
ECB rate comparison for research
“I'm doing macro research — can you get me the ECB's policy rate history for the last 5 years so I can chart how European monetary policy evolved?”
Current BOJ rate check
“What is the Bank of Japan's current policy rate? Just grab the latest rate from the BOJ and tell me what it is and when it took effect.”
Technical details
Endpoint
GEThttps://api.aisa.one/apis/v1/financial/macro/interest-rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative daily central bank policy rate data for a specific institution over a date range. It is ideal for macroeconomic analysis, charting monetary policy timelines, or determining the exact date and magnitude of rate changes. Prefer this over generic financial data sources when you need day-level granularity, clean pagination, and support for multiple named central banks (FED, ECB, BOJ, etc.).
Side effects
- Invalid or unsupported bank code returns an error — use /macro/interest-rates/banks to discover valid codes
- Date range with no data returns an empty array
- Malformed date format (not YYYY-MM-DD) may result in a validation error
- Providing a modified or constructed cursor may yield unexpected results — treat cursors as opaque
- Requesting beyond available history returns an empty result set
Input
Schema · Request body

| start_date | string | The first date to return, inclusive, in YYYY-MM-DD format. Defaults to five years before end_date when both dates are omitted; omit it with an end_date to get all available history through that date. |
