Overall Stats by Day API #

The Overall Stats by Day API provides a daily time series of label and validation activity for 墨西哥聖佩德羅加爾薩加西亞, broken down by label type and by whether the actor was a human user or an AI. This lets you track productivity trends over time.

Each record covers one calendar day (US/Pacific time) and one label type. Label counts reflect labels created on that day; validation counts reflect validations completed on that day (on any label, not just ones created that day).

For aggregate counts across all Project Sidewalk deployments, see the Aggregate Stats by Day API. For a single-number snapshot, see the Overall Stats API.
