Do this with verapliJSON for agents

Steps

Steps marked “human step” are ones only you can do: verapli never signs in, submits, pays or accepts terms for you.

  1. Sign in or create a Tabstack (Mozilla) account

    Sign in to Tabstack (Mozilla). If you have no account yet, you create it yourself; verapli does not create accounts.

    • Guided by hand
    • Human step: You sign in

    Where: https://console.tabstack.ai/signup

  2. Get an API key

    In the Tabstack console create an API key and set TABSTACK_API_KEY, or run stripe projects add tabstack/api.

    • Guided by hand
    • Human step: You press submit
    • After: Sign in or create a Tabstack (Mozilla) account

    verapli captures TABSTACK_API_KEY here by plain code: encrypted in your browser, never shown to AI.
