    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 17

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.

Discovered
adafruitio_get_dashboard

One dashboard by key. GET /dashboards/{dashboard_key}.

Discovered
adafruitio_get_data_point

One stored data point of a feed by its id. GET /feeds/{feed_key}/data/{id}.

Discovered
adafruitio_get_feed

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

Discovered
adafruitio_get_feed_chart

Aggregated 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.

Discovered
adafruitio_get_feed_details

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

Discovered
adafruitio_get_group

One group by key with its feeds. GET /groups/{group_key}.

Discovered
adafruitio_get_last_data

The most recent data point of a feed (value, location, created_at). GET /feeds/{feed_key}/data/last.

Discovered
adafruitio_get_throttle

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.

Discovered
adafruitio_get_user

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.

Discovered
adafruitio_list_activities

The account's activity log (feed/data/dashboard changes), optionally within a time range. GET /activities.

Discovered
adafruitio_list_blocks

The blocks (widgets: gauges, toggles, charts, sliders...) of a dashboard with their feeds, position and properties. Integration secrets in properties are removed. GET /dashboards/{dashboard_key}/blocks.

Discovered
adafruitio_list_dashboards

List the account's dashboards with key, name, description and visibility. GET /dashboards.

Discovered
adafruitio_list_feed_data

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.

Discovered
adafruitio_list_feeds

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

Discovered
adafruitio_list_groups

List the account's groups (named sets of feeds) with their feeds. GET /groups.

Discovered
adafruitio_publish_data_point

WRITE: 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_key}/data.
