Temperature Buckets

GET/api/v1/accuracy/by-bucket/:station_id

Accuracy by 2°F temperature range. Returns hit rates, false positives, and false negatives for each bucket. Directly maps to prediction market contract ranges — shows which 2-degree bands NWS reliably predicts versus where it misses.

Parameters

Name	Type	Required	Description
`station_id`	path	required	ICAO station identifier
`days`	integer	optional	Rolling window Default: 90
`metric`	string	optional	high (default) or low — bucket by forecast/actual low Default: high

Response Fields

Field	Type	Description
`temperature_range`	string	Bucket label (e.g., 74-76°F)
`range_low_f`	integer	Bucket lower bound °F
`range_high_f`	integer	Bucket upper bound °F
`times_actual_in_range`	integer	Days actual high was in this bucket
`times_forecast_in_range`	integer	Days forecast high was in this bucket
`times_both_in_range`	integer	Days both forecast and actual in bucket
`accuracy_when_forecast_in_range`	float	Hit rate when forecast was in bucket (0-1)
`frequency_pct`	float	Share of days actual was in this bucket
