agentcost

Know what your AI agents actually cost. Track LLM tokens, tool API calls, and compute costs — per agent, per task, per tool.

Get Started (3 commands)

pip install agentcost
agentcost login
agentcost run my_agent.py

That's it. Every OpenAI and Anthropic call inside your script is automatically tracked — zero code changes needed.

How It Works

agentcost run wraps your script, detects installed LLM libraries, and captures token usage from every API response. Events are sent to your dashboard in the background. No slowdown, no side effects.

Setup

1. Install

pip install agentcost

2. Login (one time)

agentcost login

Stores your API key securely in ~/.config/agentcost/. Get your key from agentmeter.com.

3. Run

agentcost run my_agent.py

Works with any Python script that uses OpenAI or Anthropic SDKs.

CLI Commands

agentcost login       # Save your API key (one-time setup)
agentcost run app.py  # Track a script automatically
agentcost status      # Check login status and connection
agentcost summary     # View cost summary in terminal
agentcost agents      # List all tracked agents
agentcost logout      # Remove stored credentials

Alternative: Python API

For more control, use the Python API directly:

import agentcost

# Auto-patch all LLM calls (after login, no key needed)
agentcost.init(agent_id="my-agent")

# Or with explicit key
agentcost.init(api_key="ac_xxxxx", agent_id="my-agent")

Track tool costs

from agentcost import AgentCost

ac = AgentCost()

@ac.track_tool(name="stripe_api", cost_per_call=0.02)
def charge_customer(amount):
    return stripe.charges.create(amount=amount)

Group calls into runs

with ac.track_run("support-agent", task="process_refund") as run:
    run.record("stripe_api", cost=0.02)
    run.record_llm("gpt-4o", tokens_in=500, tokens_out=200)

print(f"Run cost: ${run.total_cost:.4f}")

Custom Pricing

ac = AgentCost(
    pricing_overrides={
        "my_custom_api": 0.05,
        "my-fine-tuned-model": {"input": 5.00, "output": 15.00},
    }
)
