Tool detail

Truth Bear

Returns one official signal reading for a signal_id/entity pair against its threshold ladder, with a 5-year same-season percentile for context.

Categories: Trading signals

Use when

check a hydrology, weather or macro signal's reading against its official threshold
see if a signal's current value is routine or unusual versus 5-year history

Not for

not a forecast or advice, purely descriptive
not billed on a 422 response (no data for that pair)

Inputs

GET query params, both required: signal_id (string, e.g. hydrology.river-level), entity (string, e.g. 07010000); valid pairs via free /gauge/catalog.
