Recently, we noticed the public API key's daily quota was depleting unusually fast, suggesting abnormal or automated usage. To ensure fair access and in response to community feedback, we have transitioned the public API key to a dynamic generation model.

What's Changing?

  • The daily limit will remain unchanged at 200,000 requests.
