Keyveve

LangChain and LangGraph callback for AI usage costs, customer attribution and Veqen budgets.

What every AI request costs, by customer, feature or project, with the key hint that lets Veqen catch stolen keys. Includes the veqen CLI, with an offline coding-agent bill.

The cost ledger for AI inference: exact cost for every model call (text, embeddings, images, video, speech and transcription, across labs, open-model hosts and clouds), per customer, feature and project, with budgets.
