Anthropic
Connect Anthropic Claude models to AgentOne with your API key.
Anthropic makes the Claude family of models. AgentOne includes Anthropic as a built-in provider.
Getting an Anthropic API Key
Sign in to Anthropic Console
Go to console.anthropic.com and sign in or create an account.
Open API Keys
In the left sidebar, click API Keys, then click Create Key. Give it a name such as "AgentOne".
Copy the Key
Copy the key immediately. Anthropic only shows the full key value once.
Billing required
Anthropic requires a funded account to use the API beyond the free tier. Add credits at console.anthropic.com/settings/billing.
Connecting Anthropic in AgentOne
Open Provider Settings
In AgentOne, click Settings -> Providers.
Find and Enable Anthropic
Under Built-in Providers, locate Anthropic, expand it, and toggle the enable switch on.
Paste Your Key
Paste your API key into the API Key field and click save.
Claude models appear in the model selector immediately after saving.
Available Models
AgentOne's built-in list covers the major Claude 3 and Claude 4 series models. If Anthropic releases a new model before AgentOne's list is updated, you can register it via Add Model Override in the provider settings. See Built-in Providers.
Troubleshooting
- 401 error: double-check your API key and save again.
- Credit balance errors: top up your Anthropic balance at the console.
- Tool calls failing: verify the selected Claude model supports tools. See Model Metadata.
