this check leads to an error if the apiKey and authToken are defined in the .env file (and not the actual client file)
one can have both apiKey and authToken in the .env file and still only use one
this error should only pop up if the user passed both while initialising the provider

i assume you tested it with a URL that will accept the proper bearer token? |

…el#11782) ## Background Some use cases require `Authorization: Bearer` header authentication instead of the `x-api-key` header when using the Anthropic API. This is particularly useful when working with proxy services or custom API gateways that expect Bearer token authentication. ## Summary Added a new `authToken` option to the Anthropic provider that enables `Authorization: Bearer` header authentication as an alternative to the existing `x-api-key` authentication method. Changes: - Added `authToken` option to `AnthropicProviderSettings` - Added support for `ANTHROPIC_AUTH_TOKEN` environment variable - When `authToken` is provided, uses `Authorization: Bearer` header instead of `x-api-key` ## Manual Verification Tested locally by configuring the provider with `authToken` option and verifying the correct `Authorization: Bearer` header is sent in API requests. ## Checklist - [x] Tests have been added / updated (for bug fixes / features) - [ ] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] I have reviewed this pull request (self-review) --------- Co-authored-by: Aayush Kapoor <[email protected]> Co-authored-by: Aayush Kapoor <[email protected]>
