Trends API (v3) uses a rate limit service that allows up to 10 requests per second (RPS) per account.

The previous daily and hourly limits have been removed. These fields remain in the API response only for backward compatibility, and their values are no longer used or decreased.

Your monthly request limit depends on your Trends API subscription plan. You can use your entire monthly quota at any pace within the 10 RPS limit.
