WHAT IT DOES

What ecb-rates.policy.key_rates does on Apibase

AI agents call ecb-rates.policy.key_rates 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
`rate_type`	string	—	Which ECB key interest rate to fetch: main_refinancing (MRO rate), deposit_facility (rate banks earn on overnight deposits), marginal_lending (overnight borrowi
`end_period`	string	—	End of date range: YYYY, YYYY-MM, or YYYY-MM-DD depending on series frequency. Ignored if last_n_observations is set.
`start_period`	string	—	Start of date range: YYYY, YYYY-MM, or YYYY-MM-DD depending on series frequency. Ignored if last_n_observations is set.
`last_n_observations`	integer	—	Return only the most recent N observations (max 100). Takes precedence over start_period/end_period. Default 10 if no range given.

Parameters from the server's own tool schema.
