Overview

Some functions in the Standard Mode rely on our self-hosted servers. If you see these "error" subtitles:

{ machine translation has exceeded the free quota } { speech recognition has exceeded the free quota }

It means that you are using server functions, but the server refuses to process it.

Because we have certain costs for operating servers, we cannot provide unlimited free quota. Users need to pay to obtain more quota.

  • If you are not willing to pay, then you can close the corresponding subtitle menu, or use the Native Mode.
  • If you are willing to pay, then you need to purchase and set up an API key.

API keys

An API key is a random string, for example, 24c12dac-9608-4d08-b35e-81be10b22372.

  • The API key cannot be made public or leaked to others.
  • The server handles requests based on the fair usage policy.
