Who owns what

A Mistral account belongs to an organisation; the organisation holds billing and one or more workspaces; API keys are scoped to a single workspace.

  • Mistral account personal owned by the person
  • Organisation organisation owned by the company · under Mistral accountCreated on first Studio login; holds billing, SSO and members (Admin, Billing, Member roles).
  • Workspace project owned by the company · under OrganisationA default workspace is created automatically; each workspace has its own keys, usage and optional monthly budget.

Mistral suggests at least two workspaces (development and production) so test traffic does not consume production quotas.

Have ready

  • An email address to create a Mistral account
  • Admin or Billing role in the organisation to activate billing
  • Payment card (or an AWS / Azure Marketplace account) to activate billing · Team members cannot generate working API keys until billing is active [1]Needed for: Activate billing in Admin

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 or log in at console.mistral.ai

    You create the account yourself. New accounts are prompted to name their organisation and are redirected to Admin.

    • Guided by hand
    • Human step: You sign in

    Where: https://console.mistral.ai/

  2. Accept Mistral's terms

    Business API use is governed by the Commercial Terms of Service and Usage Policy. You accept them yourself. [to verify where acceptance is shown in sign-up]

    • Guided by hand
    • Human step: You accept the terms
    • After: Sign up or log in at console.mistral.ai

  3. Activate billing in Admin

    In Admin > Subscriptions > Billing, click Add payment method and connect a card or cloud marketplace account; optionally set a monthly spending limit. Pay-as-you-go is prepaid, so buy credits and enable it at admin.mistral.ai/subscription. verapli never touches payment details.

    • Guided by hand
    • Human step: You add payment details
    • After: Accept Mistral's terms
    The provider says
    Billing takes 2-3 minutes to take effect. [1]
    If something goes wrong (1)
    • New keys show as inactive: Wait a few minutes after activating billing, then retry. [1]

    Where: https://admin.mistral.ai/organization/billing

    If something goes wrong (1)
    • API requests return HTTP 429 mid-month: The workspace monthly spending limit was reached; raise it under Admin > Subscriptions > Billing or wait for the next cycle. [4]

    Where: https://admin.mistral.ai/organization/workspaces

  5. Create an API key in Studio

    In Studio > API Keys pick the workspace, click Create new key, set name, expiration and connector access scope, then copy the key. The full key appears only once; verapli writes it to your env file.
