How this service works
Historical and current Japanese interest-rate series from the Bank of Japan's official Time-Series Data Search Site: the unsecured overnight call rate (proxy for the BOJ policy rate operating target, daily since 1998) and the basic discount/loan rate (formerly 公定歩合, daily since 1882). Factual published data only; not investment advice or a rate forecast.
Output
An array of dated observations for the requested BOJ rate series (call_rate_on or discount_rate), each with a period timestamp and rate value, filtered to the requested date range and limited to the specified number of rows (default 100 most recent).
Example use cases
Example prompt
“What's the Bank of Japan overnight call rate been doing over the last 24 months? Pull the call_rate_on series starting from January 2023 — I want to see the full monthly history.”

Endpoint
GEThttps://api.agentfeeds.jp/v1/boj/ratesWhen to prefer
Use this endpoint when you need official Bank of Japan interest rate data — specifically the unsecured overnight call rate (BOJ policy rate proxy, daily since 1998) or the basic discount/loan rate (公定歩合, daily since 1882) — directly from BOJ published figures. Prefer this over scraping BOJ's website or using general financial data APIs when you need clean, structured, machine-readable Japanese central bank rate data with a defined cost per call.
