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.
Above 150,000 rows you'll need a free API key, which you can request from the dialog itself. Keys arrive by email in seconds.
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.
Downloads here are measurements. Argus also serves modelled estimates through key-free public endpoints — background concentration anywhere in the UK and Ireland, and the health benefit of an area meeting the WHO guidelines. Both are documented in the API guide, with methods and citations under sources and methods.
