Follow these steps to get an API key from Anthropic and set usage limits. You’ll need this key for the Plugin AI System onboarding form.
Go to console.anthropic.com and sign up (or log in). You’ll need an email address and a way to verify it.
Anthropic requires a payment method to use the API. Go to Settings (in the sidebar or account menu) → Billing → Payment methods, and add a card. You can set a spending limit in a later step so you stay in control.

In the left sidebar, click API Keys (under your account/settings). If you don’t see it, look for Settings or Developers first.

Click Create Key. Give it a name (e.g. “Plugin AI System onboarding”). Copy the key as soon as it’s shown — you won’t be able to see it again. Store it somewhere safe (e.g. a password manager) until you paste it into the Plugin AI System form.

In the Anthropic console, go to Settings → Usage and limits (or Billing). Set a monthly budget and/or per-minute rate limit so you don’t get unexpected charges. For a new integration, a low cap (e.g. $10–20/month) is a good start. You can raise it later.

Paste your API key into the Anthropic API Key field on the Plugin AI System onboarding form. The key is encrypted in your browser before it’s sent.
