pfc-client 0.1.3

Lightweight Python SDK for the PFC API

pfc-client

pfc-client is the lightweight Python SDK for customers integrating with the PFC API.

Install

pip install pfc-client

For local development from this repository:

pip install ./sdk/python

Quickstart

from pfc_client import PFCClient, guarded_tool

client = PFCClient(
    api_url="https://pfc-api.fly.dev",
    api_key="YOUR_API_KEY",
)

decision = client.evaluate(
    action="deploy_production",
    subject={"type": "agent", "id": "website-backend"},
    resource={"type": "service", "id": "checkout-api"},
)

print(decision)

Base URL Configuration

By default the client points to the hosted PFC API:

client = PFCClient()

To use a different environment:

client = PFCClient(api_url="https://your-pfc-host.example.com")

API Key Usage

Pass your website customer API key when creating the client:

client = PFCClient(
    api_url="https://pfc-api.fly.dev",
    api_key="pfc_live_your_api_key",
)

The SDK sends the key as the x-api-key header on evaluate requests.

Guarded Tool Example

from pfc_client import PFCClient, guarded_tool

client = PFCClient(api_key="pfc_live_your_api_key")


@guarded_tool(client)
def deploy():
    print("Deploying to production")


deploy()

Supported Operations

• client.evaluate(...) submits an action for policy and authority evaluation
• client.verify(...) verifies an artifact against a public key via the API
