FAQ
Questions about this playbook
Which AI providers can Costory import?
OpenAI, Anthropic (API and claude.ai Enterprise), Azure OpenAI, AWS Bedrock, Google Vertex AI, OpenRouter, Cursor, ElevenLabs, Kling AI and BytePlus.
How long does this playbook take to set up?
Connecting your billing data and the Costory MCP takes under 30 minutes with Terraform or CloudFormation. The playbook itself takes minutes: pick the scope, the trigger and the Slack channel. The first billing data lands the next day, and the agent starts from there.
Can we adjust what the agent does?
Yes. You choose the trigger, the scope (team, service, environment), the channel and the format, and you can pause or change it at any time.
Does Costory change anything in our cloud accounts?
No. Costory reads billing exports and the metrics you connect, and has no write access to your cloud. Actions it takes create Costory objects only: alerts, reports, dashboards and events. Your team stays in control of every change.

A feature's model cost per request rises, or a new model ships.
Choose LLM models and routing based on cost per feature
The agent tracks per-model spend for each AI feature across OpenAI, Anthropic, Bedrock and Vertex AI, and recommends where a cheaper model or a routing change could fit.
