Adafruit Io Rate Limits
Adafruit IO enforces a per-account "data points per minute" rate limit that applies across both the HTTP REST API and the MQTT broker. The rate is the same regardless of transport; concurrent HTTP and MQTT clients share the same per-minute budget. Free accounts get 30 data points per minute; Plus accounts get 60. When throttled, the broker publishes a notification to the `{username}/throttle` MQTT topic, and the REST API returns HTTP 429.
Adafruit Io Rate Limits is the machine-readable rate-limit profile for Adafruit IO on the APIs.io network, in the API Commons Rate Limits shape.
