Every download here is equivalent to a call against /api/readings/bulk. Click View API call in the dialog above to see the curl / Python snippet for your current selection — you can paste that into a notebook to reproduce the download programmatically.

See the API guide for authentication, rate limits, worked Python examples, and data caveats — or jump straight to /api/docs for the full machine-readable reference.
