Enum ApiBackend 

pub enum ApiBackend {
    Native,
    OpenRouter,
    Proxy,
}

Which endpoint family the wire talks to — selects auth header + quirks.

This is configuration, not a wire schema: all three speak Anthropic Messages (Provider::api_schema() stays "anthropic").

Variants

Native

First-party api.anthropic.com — auth via x-api-key.

OpenRouter

OpenRouter’s Anthropic-compatible endpoint (plan §9.2) — Bearer auth, betas mirrored to x-anthropic-beta, provider preferences injected.

Proxy

Any other Anthropic-compatible gateway — Bearer auth, no extra quirks.

Implementations

impl ApiBackend

pub fn detect(base_url: &str) -> ApiBackend

Detect the backend from a base URL (pinnable by setting the field directly).

openrouter.ai (any subdomain) → ApiBackend::OpenRouter; api.anthropic.com → ApiBackend::Native; anything else → ApiBackend::Proxy. Matches the “base-URL override changes the auth header” rule (ADR-0007 consequences).
