Struct Client 

pub struct Client<C: Config> { /* private fields */ }

Anthropic API client

The client is generic over a Config implementation that provides authentication and API configuration.

Implementations

impl Client<AnthropicConfig>

pub fn new() -> Self

Creates a new client with default configuration

Uses environment variables for authentication:

• ANTHROPIC_API_KEY for API key authentication
• ANTHROPIC_AUTH_TOKEN for bearer token authentication

impl<C: Config> Client<C>

pub fn with_config(config: C) -> Self

Creates a new client with the given configuration.

Panics

Panics if the reqwest client cannot be built.

pub fn with_http_client(self, http: Client) -> Self

Replaces the HTTP client with a custom one

Useful for setting custom timeouts, proxies, or other HTTP configuration.

pub const fn with_backoff(self, backoff: ExponentialBuilder) -> Self

Replaces the backoff configuration for retry logic

By default, the client uses exponential backoff with jitter.

pub const fn config(&self) -> &C

Returns a reference to the client’s configuration

impl<C: Config> Client<C>

pub const fn messages(&self) -> Messages<'_, C>

Returns the Messages API resource

impl<C: Config> Client<C>

pub const fn models(&self) -> Models<'_, C>
