Installation

pip install buildit-argus

Quick start

import argus

argus.init(
    endpoint='https://api.buildit.sh',
    api_key='bld_live_...',  # Settings → API Keys on app.buildit.sh
)

Usage

Anthropic

Wrap your Anthropic client once — every messages.create call is tracked automatically.

import anthropic
import argus

argus.init(endpoint='https://api.buildit.sh', api_key='bld_live_...')

client = argus.wrap_anthropic(anthropic.Anthropic())

msg = client.messages.create(
    model='claude-haiku-4-5-20251001',
    max_tokens=1024,
    messages=[{'role': 'user', 'content': 'Hello'}],
)

OpenAI

from openai import OpenAI
import argus

argus.init(endpoint='https://api.buildit.sh', api_key='bld_live_...')

client = argus.wrap_openai(OpenAI())

res = client.chat.completions.create(
    model='gpt-4o-mini',
    messages=[{'role': 'user', 'content': 'Hello'}],
)

Manual tracking

result = argus.track(
    provider='my-provider',
    model='my-model-v1',
    fn=lambda: my_llm_call(),
    op_name='chat',  # optional label shown in dashboard
)
