the sweep

what's a sweep?

roazon checks every roaster on the radar every weekday. each completed check across the whole site is one "sweep" — this chart plots how many beans were newly listed, dropped in price, or came back in stock at each of the last sweeps.

the window is capped to the most recent 60 sweeps (about 70 days at the every-weekday cadence), so the chart stays a fixed size no matter how long roazon has been running. the same bounded series is published as JSON at /api/v1/sweeps.json.
