Install

Install Reqbook CLI and API workflow notebook

Install Reqbook with the shell installer, npm, crates.io, Homebrew, Docker, Windows MSI, VS Code extension, or source checkout.

Recommended install

shell installer
$ curl -fsSL https://markapidown.net/install.sh | sh
$ rqb init --yes
$ rqb serve

Verify the API notebook workflow

After installation, create or import specs under api-docs/, validate the files, and run the local browser workspace.

$ rqb version
$ rqb doctor
$ rqb validate api-docs/
$ rqb exec api-docs/
$ rqb serve

If your team uses coding agents, run rqb skills install after the first specs are committed. See the FAQ or the Claude Code API testing guide.
