Environment variables
  • THREE_WS_BASEBase URL of the three.ws API that serves the billing endpoints. Override only when self-hosting or targeting a preview deployment.
  • THREE_WS_TIMEOUT_MSPer-request timeout in milliseconds for the live three.ws API reads.
  • THREE_WS_SESSIONrequiredsecretYour three.ws session token (the value of the `__Host-sid` cookie from a signed-in browser). REQUIRED: it exposes private billing data, so every account-scoped read (get_billing_summary, query_usage, export_billing_history, get_receipt) resolves the calling user from it and returns only your data. Only the public get_fee_info works without it. Treat like a password.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
