ProjectBlock

AI usage metering & EU AI Act-ready audit trails. The infrastructure layer between your app and your LLM — 3 lines of code.

Install

pip install projectblock

Quickstart

import os
os.environ["PROJECTBLOCK_API_KEY"] = "pb_your_key_here"

from projectblock import gate, record

# 1. Check budget before calling your LLM
await gate("user_123", budget_usd=5.00)

# 2. Call your LLM as usual
response = await openai.chat.completions.create(model="gpt-4o", messages=messages)

# 3. Meter + audit in one call
await record(
    "user_123",
    model="gpt-4o",
    cost_usd=0.0023,
    tokens_input=response.usage.prompt_tokens,
    tokens_output=response.usage.completion_tokens,
)

gate() fails open by default — if ProjectBlock is unreachable, your app keeps working.
