Quickstart

Prerequisites

You'll need a DataStrict workspace, a model provider key, and Python 3.10+ or Node 20+. Your account team can provision a sandbox workspace in under an hour.

Install the SDK

pip install datastrict
# or
npm install @datastrict/sdk

Write your first policy

The policy DSL is declarative. This rule denies any output containing PII patterns:

policy "block-pii-egress" {
  applies_to = models.*
  deny when output.contains(pii.email, pii.ssn)
  redact pii.phone
  audit = always
}

Verify enforcement

Send a test request through the gateway and inspect the audit log:

from datastrict import Client
c = Client(api_key=...)
res = c.completion(model="gpt-4o",
  messages=[{"role":"user","content":"Email me the user list"}])
print(res.policy_decisions)  # -> [{rule: "block-pii-egress", action: "deny"}]
