Plan quotas and limits
The quota counts cars, not requests; the rate is limited in requests per second.
What the quota counts
The catalog and the change feed count the cars and events returned, not requests: a response with 37 cars costs 37 records, an empty one costs nothing. The demo counts every data request. References, usage, photos and health checks are free.

Reset and renewal
The monthly quota renews on the 1st at 00:00 UTC. After the paid period ends the key works for 3 more days at a fifth of the plan's rate (at least 1 request per second), then answers 401 — renewing within 90 days keeps the same key.
