Create an Anthropic API key in the Claude Console and add it under Zinn® AI → Your keys, so Claude-powered features run on your own Anthropic account.
You do not need a key of your own — Zinn® AI runs on your Zinn® AI credits by default. Adding your own Anthropic key means the AI features that use Anthropic run on your Anthropic account, at Anthropic's own prices, billed by Anthropic. Some models are marked needs your own key; those only become available once you add one.
An account on the Claude Console with billing set up — Anthropic bills API use there, and the spend limits for your account are shown on its Billing page.
Sign in to the Claude Console and open Settings → API keys (the Console's Account Settings). Create a key, choosing its type and its expiration. If you use workspaces, create it in the workspace you want the spend to land in. Copy the key when it is shown.
This is not on the Integrations screen. Open Zinn® AI in your dashboard and the Your keys tab. Choose Anthropic (Claude) as the provider, paste the key, give it a name you will recognise, and press Save key.
The key goes straight into our secrets vault — never our database — and is never shown again, not even to you.
Press Test it beside the key. It shows Working, Not working or Not tested yet, and we keep re-checking a saved key so a revoked one is noticed.
AI features that use Anthropic now run on your account. The key's row shows when it was last used. If Anthropic refuses a request because of your key — it was revoked, or your Anthropic account is out of credit — we tell you it is your Anthropic account that needs attention, so you are not left guessing whether the fault is ours.
Not working. The key was revoked or has reached its expiration, or your Anthropic account has no remaining credit or has hit its spend limit. Check Billing and Rate limits in the Claude Console.
Not working straight after saving. Check that nothing extra was copied with the key, and that the key was created in the account you meant — many people have more than one.
On Your keys, press Stop using this key and confirm. We delete it from our secrets vault and your AI goes back to running on Zinn® credit. Revoke the key at Anthropic too if it may have leaked; removing it here deletes our copy, not theirs.

How hosting shapes indexing and link equity in 2026: keeping pages indexed, vetting aged domains before you build on them, link building without a footprint, and an honest line on what infrastructure can and cannot do for SEO.
