Enum AuthScheme 

pub enum AuthScheme {
    ApiKey,
    AwsSigv4,
    GcpOauth,
}

How a provider call is credentialed — orthogonal to Dialect (ADR 0006): dialect shapes the request/response body, auth scheme shapes how the request is signed/credentialed. Default (api_key_env / BYOK header) is unchanged for every existing [[provider]] entry.

Variants

ApiKey

API key in a header (x-api-key, Authorization: Bearer, or x-goog-api-key) — today’s behavior for anthropic / openai / gemini.

AwsSigv4

AWS SigV4 request signing (Bedrock) — credentials from AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / AWS_SESSION_TOKEN, region-scoped.

GcpOauth

GCP OAuth2 bearer token (Vertex AI) — minted and cached by gcp_auth from GOOGLE_APPLICATION_CREDENTIALS or the ambient environment.
