list_indicators
Retrieve metadata for all available electricity indicators from Spain's grid operator, including IDs, names, units, frequencies, and geographic scopes.
Instructions
List all available electricity indicators from REE.
Returns metadata for all 1,967+ available indicators including their IDs, names, units, frequencies, and geographic scopes.
Args: limit: Maximum number of indicators to return (default: all) offset: Number of indicators to skip for pagination (default: 0)
Returns: JSON string with list of indicator metadata.
Examples: Get first 50 indicators: >>> await list_indicators(limit=50, offset=0)
Get all indicators:
>>> await list_indicators()Input Schema
