To connect one, give it `set up https://fous.com/SKILL.md`. ## Ask your agent - What are the ECB's current deposit facility, main refinancing, and marginal lending rates and when did they take effect? - Show me the latest euro area key interest rates from the European Central Bank on europa.eu, plus the last 15 rate changes. - Can you tell me the ECB deposit rate right now and the date it became effective? - I need the current main refinancing operations rate set by the ECB, along with its effective date and a history of the previous changes. - Pull up the European Central Bank's marginal lending facility rate and the deposit facility rate, including the 5 most recent earlier adjustments. ## Input schema ```json { "type": "object", "required": [], "properties": { "max_results": { "type": "integer", "default": 10, "maximum": 100, "minimum": 1, "description": "Maximum number of earlier changes to return when history is included.
