WHAT IT DOES

What norgesbank.rates.history does on Apibase

AI agents call norgesbank.rates.history to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`end_date`	string	—	End date of the historical range in ISO 8601 format (YYYY-MM-DD or YYYY-MM). Defaults to today if omitted.
`frequency`	string	—	Observation frequency: "B" = business daily (default), "M" = monthly average, "A" = annual average.
`rate_type`	string	—	Type of key policy rate to retrieve: "SD" = key policy rate (deposit rate), "OL" = overnight lending rate, "RR" = reserve rate. Omit to get all three types.
`start_date`	string	—	Start date of the historical range in ISO 8601 format (YYYY-MM-DD or YYYY-MM). Defaults to 1 year ago if omitted.
