Sharing one API account across Claude Code and Codex

Agent tools are used more often, and teams quickly run into the cost of configuring keys, balances, and provider choices for every tool.

A cleaner approach is to point Claude Code, Codex, Cursor, and custom agents at one compatible API entry, then monitor usage and cost in the console.

This does not change the core model traffic path. High-volume /v1 requests continue through Sub2API and CPA; the frontend handles configuration, education, and visibility.
