Struct AnthropicClient 

pub struct AnthropicClient {
    api_key: Option<SecretString>,
    endpoint: String,
    model: String,
    client: Client,
}

Anthropic Claude LLM client.

API keys are stored using SecretString which zeroizes memory on drop, preventing sensitive credentials from lingering in memory after use.

Fields

api_key: Option<SecretString>

API key (zeroized on drop for security).

endpoint: String

API endpoint.

model: String

Model to use.

client: Client

HTTP client.

Implementations

impl AnthropicClient

pub const DEFAULT_ENDPOINT: &'static str = "https://api.anthropic.com/v1"

Default API endpoint.

pub const DEFAULT_MODEL: &'static str = "claude-3-haiku-20240307"

Default model.

pub fn new() -> Self

Creates a new Anthropic client.

pub fn with_api_key(self, key: impl Into<String>) -> Self

Sets the API key.

pub fn with_endpoint(self, endpoint: impl Into<String>) -> Self

Sets the API endpoint.

pub fn with_model(self, model: impl Into<String>) -> Self

Sets the model.

pub fn with_http_config(self, config: LlmHttpConfig) -> Self

Sets HTTP client timeouts for LLM requests.

fn validate(&self) -> Result<()>

Validates that the client is configured with a valid API key (SEC-M1).

Anthropic API keys follow the format: sk-ant-api03-... (variable length). This validation ensures early rejection of obviously invalid keys.

fn is_valid_api_key_format(key: &str) -> bool

Checks if an API key has a valid format (SEC-M1).

Valid Anthropic keys:

• Start with sk-ant- prefix
• Are at least 40 characters (typical keys are 100+ chars)
• Contain only alphanumeric characters, hyphens, and underscores

This validation catches obviously malformed keys early, before making network requests that would fail with 401 errors.

fn request(&self, messages: Vec<Message>) -> Result<String>

Makes a request to the Anthropic API.
