THE PROBLEM
AIcostsareinvisibleuntiltheydestroyyourrunway.
You get one monthly invoice. You have no idea which agent, workflow, or runaway loop caused half of it. By the time you notice, it's already expensive.
INTEGRATIONS
PLATFORM
Three steps to full cost clarity.
01
Point your SDK at Kostly
Change one line. Your existing code keeps working — every call now flows through the proxy.
# Before
client = OpenAI()
# After
client = OpenAI(
base_url="https://api.kostly.dev"
)
02
Tag calls with context
Pass agent and task metadata in headers. Kostly attributes costs automatically.
headers={
"x-agent-id": "research-bot",
"x-task-id": "summarise-docs"
}
03
Read the dashboard
See cost by agent, model efficiency, zombie alerts, and savings — in real time.
