In order to ensure service stability, requests without an API key will be subject to access frequency limitations. Currently, requests without a key are limited to 20 requests per second. However, starting from next week (July 10, 2023, 8:00:00 UTC), the access frequency for requests without a key will be adjusted to 10 requests per second.
We urge all developers to promptly switch their calling methods to avoid any disruptions to the service.
For information on how to use the API key, please refer to the following link: https://docs.tronscan.org/getting-started/api-keys
Thank you for your support!
