Connect Anthropic

Use the Anthropic API format when your service speaks the Anthropic Messages API.

Add the service

1. Open Settings and go to Services.
2. Add a new service or edit an existing one.
3. Set API Format to Anthropic.
4. Enter a recognizable Name.
5. Enter the service address.
6. Enter and save the Anthropic Access Key.
7. Add the Model ID from your Anthropic console or provider documentation.
8. Click Test Connection.

Address examples

Use Service Root for a base address:

https://api.anthropic.com/v1

Use Full Request Address for the complete Messages endpoint:

https://api.anthropic.com/v1/messages

Notes

Model discovery works with Service Root mode when Anthropic exposes a model list. With Full Request Address, add the model manually.

The service must support the Anthropic API request format. Anthropic-compatible proxies and gateways can be used the same way.
