# BizOS CLI & API > BizOS is a thin, secure command-line client over the billing-enforced BizOS API. The `bizos` CLI lets AI agents and humans run tasks, manage documents and leads, generate ad creatives, manage landing pages, read Meta campaign data, and inspect the credit wallet — all from the terminal. Credit-spending commands require `--yes`. 1 credit = 1 task run or 1 creative. ## Documentation - [Introduction](https://docs.bizos.lol/docs): What BizOS is, what the CLI does, and the thin-client-over-a-billing-enforced-API model. - [Quickstart](https://docs.bizos.lol/docs/quickstart): Install the CLI, create an API key, log in, and verify — in under two minutes. - [Use with Claude Code](https://docs.bizos.lol/docs/claude-code): A ready-to-paste prompt that teaches Claude Code (or any AI agent) to drive BizOS through the CLI. - [Authentication](https://docs.bizos.lol/docs/authentication): API keys — how they're scoped to one org, how they're secured, and the env vars the CLI reads. - [Commands reference](https://docs.bizos.lol/docs/commands): Every bizos command group — description, usage, flags, examples, JSON output, and credit markers. - [API reference](https://docs.bizos.lol/docs/api-reference): The raw /api/cli/* endpoints — method, path, auth, body, response, and cost — for calling BizOS directly. - [Billing & credits](https://docs.bizos.lol/docs/billing): How credits and the prepaid wallet work, what spends them, and how to handle 402 out-of-credits responses. ## Machine-readable - [Full docs as one file](https://docs.bizos.lol/llms-full.txt): every page inlined as markdown. - Per-page markdown: append `/content.md` patterns are exposed at https://docs.bizos.lol/llms.mdx/docs//content.md
