Help verify Superserve

Have a Superserve account? These run real sandboxes on it, for a few cents at most, and write result files that fill in the blanks above. Results never include your keys. Run them in a clone of the repo and open a pull request with the files: CI checks every file for keys and impossible numbers, and a maintainer reviews each one before it shows here.

npx @sandboxrouter/sdk cost run --provider superserve --minutes 10 --by YOUR_GITHUB_USERNAME
