Steps

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

  1. Sign up for E2B

    The person signs up at e2b.dev. verapli never creates the account.

    • Guided by hand
    • Human step: You press submit

    Where: https://e2b.dev/auth/sign-up

  2. Copy the API key

    Open the dashboard keys tab and copy the API key into E2B_API_KEY.

    • verapli co-pilot
    • After: Sign up for E2B

    verapli captures E2B_API_KEY here by plain code: encrypted in your browser, never shown to AI.

    Where: https://console.e2b.dev/?tab=keys
