Without a key every query reads one free sample day for every venue, whatever dates are asked (the response's tier, free_day and range say what was read); a caller that connects to https://fronresearch.com/api/agent with "Authorization: Bearer " reads the history its plan covers (a site's own /api/agent does not forward keys). Start with endpoint index (the sample day and endpoints), then markets or venues to get ids, then metrics. Fields, filters and how to get a key: https://fronresearch.com/data/history/ - after: Structured rows from the Fron Research Data API (https://api.fronresearch.com/v1): markets, venues, bookable slots and a utilization and a revenue estimate per venue, market or day. Without a key every query reads one free sample day for every venue, whatever dates are asked (the response's tier, free_day and range say what was read); a caller that connects to https://fronresearch.com/api/agent with "Authorization: Bearer " reads the history its plan covers (a site's own /api/agent does not forward keys).
