Rulvar API reference / @rulvar/rulvar / anthropic
Function: anthropic()
function anthropic(options?): ProviderAdapter;Defined in: packages/anthropic/dist/index.d.ts
Creates the first-class Anthropic adapter (id 'anthropic'). SDK autoretries are disabled (max_retries 0): the core owns retries and wall-clock. With no auth option at all, the underlying SDK resolves credentials itself: it reads ANTHROPIC_API_KEY and ANTHROPIC_AUTH_TOKEN as INDEPENDENT credentials, never a precedence chain between the two; requests carry x-api-key for the key, bearer Authorization for the token, and BOTH headers when both are set (the server decides). The SDK's config-file credential chain (credentials, else config, else profile) is consulted ONLY when apiKey and authToken are both null; either one set, an env-read one included, means a configured token provider is never even built. When sdkOptions carries structured auth and no apiKey/authToken is set to a string anywhere, ambient environment credentials are suppressed (explicit apiKey: null, authToken: null are passed to the SDK), so the configured provider is the one that authenticates; the SDK itself would otherwise let an environment ANTHROPIC_API_KEY or ANTHROPIC_AUTH_TOKEN win over the provider. An explicit apiKey: null or authToken: null counts as absence for this rule, never as a chosen credential. The full matrix lives in the providers guide under anthropic-credential-precedence.
