}Interbank rate history (US/JP)
Ten years of interbank rates for one country — overnight, 1-week, 1-month, 3-month and 6-month —
plus the latest overnight and 3-month reading. A tenor the source does not publish is null, never 0
(the US only has overnight). For Japan’s daily TIBOR and official overnight call rate use
/macro/interbank-rates/jp/tibor and /macro/interbank-rates/jp/overnight; for Vietnam use
/macro/interbank-rates/vn.

Your HayInsights API key (prefixed apk_). Create and manage keys in the
HayInsights dashboard (Account → API keys).
Send it in the X-API-Key header on every request to /openapi/v1/*.
Which data domains you may access and your request quota are both governed by
the subscription plan attached to the key — see the Plans & features and
Rate limits guides.
