Occludra — AI Security Gateway (Python SDK)

Occludra is a drop-in security proxy for LLM API calls: PII/DLP redaction, prompt-injection defense, recursive-loop protection, hard budget caps, and smart routing across 600+ models — plus enterprise controls (SSO, RBAC, SIEM, Hybrid VPC, and the MCP Gateway for the agent tool plane).

pip install occludra

from occludra import Occludra

client = Occludra(api_key="oah_...")

res = client.chat.create(
    model="oah/llama-4-maverick",
    messages=[{"role": "user", "content": "My email is test@example.com"}],
)
print(res.content)
print(res.aisg_metadata.pii_detected)           # True
print(res.aisg_metadata.entity_types_detected)  # ["EMAIL_ADDRESS"]

Prefer the OpenAI SDK? Point its base URL at the gateway — no new dependency:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aisecuritygateway.ai/v1",
    api_key="oah_...",
)

Stable identifiers (unchanged by design)

Occludra is the officially branded distribution of the SDK — it re-exports the stable aisg client, so this package is fully functional today. A few identifiers stay unchanged because they are permanent wire/product contracts that existing integrations depend on:

• Proxy base URL: https://api.aisecuritygateway.ai/v1
• Response field: response.aisg_metadata
• Environment variables: AISG_API_KEY, AISG_BASE_URL

Both client names work: Occludra is the branded name; AISG is kept for backward compatibility.
