# Reqbook CLI for API Testing

> Run Reqbook from the terminal to validate, execute, flow-test, import, and package markdown API specs for coding agents.

## What is rqb-cli?

**rqb-cli** is the terminal interface to Reqbook. Every capability is accessible as a subcommand.

Use it for:

* Scripted API testing and CI/CD pipelines
* Importing and validating specs
* Running ad-hoc HTTP requests from the terminal
* AI agent tool integration via MCP

## Same binary two interfaces

```
rqb serve → opens rqb-ui in your browser
rqb exec → runs in the terminal (rqb-cli)
```

Both ship in one binary. There is no separate installation.
