Set it up

Aria & agents (recommended)

1. Create a key. In the Anthropic Console, open API keys, click Create Key and copy it. It starts with sk-ant-.
2. Open Settings › Providers and click + Add provider.
3. Pick Anthropic as the Provider, give it a Label and paste the key into API key.
4. Type the Model id (a Claude model id from Anthropic’s model list), then click Add.
5. Optionally click Set as default, so Aria and agents set to Same as Aria use it.

Check it's connected — 

Open a chat, pick the provider’s model in the model menu and send Hello: the reply comes from Anthropic. A wrong key shows a provider error in the chat right away.

Where your token lives

Where your token lives — 

The credential is stored where you choose when you create it:

• Local (this browser only): encrypted in this browser. The encryption key is kept on the same device, so turn on the local secret vault to lock it with a passphrase only you know.
• Cloud (synced to your account): sent over an encrypted connection and stored encrypted on AWFlow’s server, so it works on your other devices.

When a step runs, your browser sends it only to api.anthropic.com. AWFlow’s servers never relay the call.

Keys added in Settings › Providers are separate: they stay on this device only, encrypted, and are never synced to your account.

Common issues

• A 401, “invalid API key” or “Incorrect API key” error. The key was mistyped, revoked, or belongs to another account. Create a new key and update the credential (or the provider in Settings › Providers).
• A 429 or “quota” error. The account is out of credit or over its rate limit. Add credit or wait, then run again.
• An embeddings node fails with 401 while a chat node with the same key works. The credential is a Bearer Token. Embeddings nodes pass the value to the provider as it is, so use a JWT credential that holds only the key.
