Installation

Install the CLI globally so the spectrum binary is on your PATH.

npm

npm install -g @spectrumnodes/cli

yarn

yarn global add @spectrumnodes/cli

pnpm

pnpm add -g @spectrumnodes/cli

Verify

spectrum --version
spectrum --help

One-off runs

To try the CLI without a global install, run it with npx:

npx @spectrumnodes/cli prices price ETH

Requirements

• Node.js 20 or later. The CLI uses native fetch, so no polyfill is needed.
