98Call `GetWebIdentityToken` with `https://api.anthropic.com` as the audience, then pass the result to the SDK's federation credentials. Because `identity_token_provider` (typescript, php: `identityTokenProvider`; csharp: `IdentityTokenProvider`; go: `option.WithFederationTokenProvider`; java: `federationTokenProvider`) takes a callable, the SDK re-invokes STS on each refresh.

101101 `GetWebIdentityToken` is available only on regional STS endpoints. If you receive `'STS' object has no attribute 'get_web_identity_token'` or a similar error, pin your STS client to a region (for example, `boto3.client("sts", region_name="us-east-1")`) and ensure your AWS SDK is recent enough to include the API.
