trakr-monitor 0.1.1

AI agent cost and failure monitoring — Sentry for AI agents

trakr-monitor

Observability SDK for AI agent workflows. Automatically captures Anthropic and OpenAI LLM calls with cost, tokens, latency, and tool use — sent to your Trakr dashboard.

Install

pip install trakr-monitor

# With Anthropic auto-instrumentation
pip install trakr-monitor[anthropic]

# With OpenAI auto-instrumentation
pip install trakr-monitor[openai]

Quick start

import trakr_monitor as trakr
import anthropic

trakr.init()  # reads TRAKR_API_KEY

client = anthropic.Anthropic()

with trakr.start_run("daily-report") as run:
    client.messages.create(
        model="claude-sonnet-4-6",
        max_tokens=256,
        messages=[{"role": "user", "content": "Summarize logs"}],
    )

trakr.flush()  # blocking — call before sys.exit() in scripts

Decorator pattern

import trakr_monitor as trakr

trakr.init()

@trakr.track_agent(name="invoice-extractor")
def extract_invoice(document: str) -> dict:
    return do_extraction(document)

Async functions are supported:

@trakr.track_agent(name="async-processor")
async def process_async(data: str) -> str:
    return await call_llm(data)

Local development

import os
import trakr_monitor as trakr

trakr.init(
    api_key="tk_live_testkey00000000000000000000000000",
    endpoint=os.environ.get("TRAKR_INGEST_URL", "http://localhost:3000/api/ingest"),
)

API

trakr.init(...)
trakr.start_run(workflow_name, ...) -> Run  # context manager
trakr.track_agent(name, metadata=None)    # decorator
trakr.flush()                             # blocking flush
trakr.disable()

run.end(status="success" | "error", error_message=None)
run.set_metadata(key, value)
