Our number of queries should not hit the limits unless you are running `espup install` command numerous times in a short span of time. We recommend setting the [`GITHUB_TOKEN` environment variable](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#about-the-github_token-secret) when using `espup` in CI, if you want to use `espup` on CI, recommend using it via the [`xtensa-toolchain` action](https://github.com/esp-rs/xtensa-toolchain/), and making sure `GITHUB_TOKEN` is not set when using it on a host machine.
