• adafruitio_get_user read-only

  The 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.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_get_throttle read-only

  The 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.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_list_feeds read-only

  List all of the account's feeds with key, name, description, unit, visibility, enabled flag, last value and last update. GET /feeds.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_get_feed read-only

  One feed by key: name, description, unit, visibility, last value, status settings and the groups it belongs to. GET /feeds/{feed_key}.

  Parameters:

  • feed_key (required) — string — Feed key (the URL-safe key shown in Adafruit IO, for example 'temperature'; 'group-key.feed-key' also works).

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_get_feed_details read-only

  A feed with its details block: first and last data point and the number of stored points. GET /feeds/{feed_key}/details.

  Parameters:

  • feed_key (required) — string — Feed key (the URL-safe key shown in Adafruit IO, for example 'temperature'; 'group-key.feed-key' also works).

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_list_feed_data read-only

  Data 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.

  Parameters:

  • feed_key (required) — string — Feed key (the URL-safe key shown in Adafruit IO, for example 'temperature'; 'group-key.feed-key' also works).
  • limit — integer — Maximum records to return, 1-1000 (default 100).
  • before — string — Pagination token: next_before from the previous reply (keep the same other arguments).
  • include — string — Comma-separated fields to return: value, lat, lon, ele, id, created_at.
  • end_time — string — ISO 8601 date or date-time, e.g. 2026-10-01T00:00:00Z.
  • start_time — string — ISO 8601 date or date-time, e.g. 2026-10-01T00:00:00Z.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• adafruitio_get_last_data read-only

  Parameters:

• adafruitio_create_feed

  WRITE: 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.

  Parameters:

  • name (required) — string — Feed name (the key is derived from it).
  • group_key — string — Optional existing group key to create the feed in.
