adafruitio_get_userread-onlyThe Adafruit IO account this key belongs to: id, name, username, time zone, created/updated times, plus the data rate limit when reported. GET /api/v2/user.
adafruitio_get_throttleread-onlyThe account's data rate limit (data-record modifications per minute: 30 on free accounts, 60 on Plus) and the current active data rate. Check it before publishing many points. GET /api/v2/{username}/throttle.
adafruitio_list_feedsread-onlyList all of the account's feeds with key, name, description, unit, visibility, enabled flag, last value and last update. GET /feeds.
adafruitio_get_feedread-onlyOne feed by key: name, description, unit, visibility, last value, status settings and the groups it belongs to. GET /feeds/{feed_key}.

adafruitio_list_feed_dataread-onlyData points of a feed (max 1000 per call). Newest first, except that with start_time the API returns the oldest page after that time. Filter by time range and limit; to read further back call again with the reply's next_page_args (the same filters plus `before`). GET /feeds/{feed_key}/data.
adafruitio_get_last_dataread-onlyThe most recent data point of a feed (value, location, created_at). GET /feeds/{feed_key}/data/last.
adafruitio_get_data_pointread-onlyOne stored data point of a feed by its id. GET /feeds/{feed_key}/data/{id}.
adafruitio_get_feed_chartread-onlyAggregated chart data for a feed: values sliced by `resolution` minutes over the last `hours` (or a start/end range), using avg, sum, min, max, val or val_count. Good for trends without downloading every point. GET /feeds/{feed_key}/data/chart.
adafruitio_list_groupsread-onlyList the account's groups (named sets of feeds) with their feeds. GET /groups.

adafruitio_list_activitiesread-onlyThe account's activity log (feed/data/dashboard changes), optionally within a time range. GET /activities.
adafruitio_publish_data_pointcan modifyWRITE: publish one data point (a value) to a feed. This can drive REAL DEVICES: anything subscribed to the feed (relays, motors, lights, heaters, locks, dashboard toggles) will receive and may act on the value, and it cannot be undone from here. Only publish a value the user has asked for. Counts against the account's data rate limit (30 per minute on free accounts, 60 on Plus). POST /feeds/{feed_
adafruitio_create_feedWRITE: create a new, empty feed (private by default), optionally inside an existing group. Adds a feed only; it does not change or delete anything existing, and fails if the name is taken. POST /feeds.
