Ably

Retrieve historical messages published to a channel, newest-first by default. REST: GET /channels/{channel}/messages.

List the members currently present on a channel (who is online now). REST: GET /channels/{channel}/presence.

Get status and occupancy metrics for a single channel (connections, publishers, subscribers, presence members). REST: GET /channels/{channel}.

Enumerate channels that are currently active in the app. Requires the API key to have the 'channel-metadata' capability. REST: GET /channels.

Retrieve message/connection/channel usage statistics for the app tied to the API key, bucketed by time. REST: GET /stats.

Return the current Ably service time in ms since epoch. Useful for aligning start/end windows to the server clock. REST: GET /time.

WRITE: publish a message to a channel. Every connected subscriber receives it in real time. This is a real, outward-facing side effect — confirm the channel and payload before calling. REST: POST /channels/{channel}/messages.

Return details about the configured control token: the account and user it belongs to and its capabilities. Good first call to confirm control-plane access. Control API: GET /me.

List the integration rules (reactor rules: webhooks, AWS Lambda/SQS/Kinesis, Kafka, Pulsar, etc.) configured for an app. Control API: GET /apps/{app_id}/rules.

Retrieve aggregated usage statistics across the whole account, bucketed by time. Account id is resolved from the control token when ABLY_ACCOUNT_ID is unset. Control API: GET /accounts/{account_id}/stats.
