Sequrity Client

The SequrityClient is the main synchronous client for interacting with Sequrity's API.

SequrityClient 

SequrityClient(
    api_key: str,
    *,
    base_url: str | None = None,
    timeout: int = 300,
    control: ControlConfig | None = None,
)

Synchronous client for the Sequrity API.

Thin orchestrator that owns the HTTP connection pool and delegates to product-specific namespaces.

Example 
from sequrity import SequrityClient
from sequrity.control import ControlConfig, FeaturesHeader, SecurityPolicyHeader

client = SequrityClient(
    api_key="sq-xxx",
    control=ControlConfig(
        llm_api_key="sk-xxx",
        provider="openrouter",
        features=FeaturesHeader.dual_llm(),
        security_policy=SecurityPolicyHeader.dual_llm(),
    ),
)

response = client.control.chat.create(
    messages=[{"role": "user", "content": "Hello!"}],
    model="gpt-5-mini",
)

Parameters:

  • api_key

    (str) –

    Your Sequrity API key for authentication.

  • base_url

    (str | None, default: None ) –

    Sequrity API base URL. Defaults to the SEQURITY_BASE_URL environment variable, or https://api.sequrity.ai.

  • timeout

    (int, default: 300 ) –

    Default request timeout in seconds. Defaults to 300.

  • control

    (ControlConfig | None, default: None ) –

    Configuration for the Sequrity Control product. When omitted, an empty ControlConfig is used (all defaults are None, configure per-request instead).

Methods:

  • close –

    Close the underlying HTTP client.

Attributes:

  • control –

    Sequrity Control product namespace.
