PostKing CLI: Marketing Automation That Speaks Your Language

Most marketing platforms assume you want to live in their dashboard. Click here to draft a post. Click there to schedule it. Click 47 more times to actually create something.

That's why we built the PostKing CLI.

What the PostKing CLI Actually Does

The PostKing CLI (command name: pking) is a terminal-based tool that controls the entire PostKing platform. You can authenticate, onboard brands by crawling websites, generate AI-written posts for X, LinkedIn, Instagram, schedule content calendars, repurpose existing content, and manage everything from voice profiles to domain verification.

All without opening a browser.

Here's the practical breakdown. You authenticate once with your API key. Then you can crawl a company website to extract brand voice, generate 30 days of social posts in under a minute, schedule them across platforms, and walk away. If you've got existing blog posts or URLs you want to repurpose, the CLI handles that too—turning long-form content into platform-specific snippets that actually sound like your brand.

The full source code lives on GitHub, and you can install it directly from npm in about 10 seconds.

Why We Built a CLI Instead of Just Another Dashboard

Developers think in scripts, not mouse clicks. When you're shipping fast, context-switching kills momentum. You're in your terminal deploying code, checking logs, running tests. Why should marketing require you to alt-tab into a web app?

According to the Stack Overflow Developer Survey, 87% of developers use the command line daily. It's not a preference—it's where work actually happens.

The CLI also solves a bigger problem: **working with AI agents**. If you're running autonomous agents that handle tasks while you sleep (and plenty of people are in 2026), those agents need programmatic access. They can't click buttons. They can execute commands, parse JSON, and make decisions based on structured output.

PostKing CLI speaks that language natively.

What You Can Do Right Now

Install the CLI with npm:

npm install -g postking-cli

Authenticate with your API key (grab one from your PostKing dashboard):

pking login

Onboard a brand by entering your website:

pking onboard --url https://yourstartup.com

The CLI scrapes the site, analyzes tone, extracts key messaging, and builds a voice profile. That profile powers every post it generates later, so your automated content doesn't sound like a generic bot wrote it.

Generate 10 LinkedIn posts based on that voice:

pking generate --platform linkedin --count 10

Schedule them across the next 2 weeks:

pking schedule --interval 2d

Done. You just automated 2 weeks of LinkedIn presence in 4 terminal commands.

Repurposing Content Without Copy-Paste Hell

If you've written a blog post that took 6 hours to research, you should get more than one piece of content out of it. The CLI's repurpose function takes a URL, raw text, or a local markdown file and splits it into platform-specific posts.

Example: you wrote a 2,000-word guide on API design. Run this:

pking repurpose --url https://yourblog.com/api-design-guide --platforms twitter,linkedin

It'll extract key points, rewrite them in your brand voice, and output 5 tweets plus 3 LinkedIn posts. Each one stands alone, references the original post, and fits the character limits and norms of each platform.

No manual reformatting. No trying to remember which points you already posted.

Voice Profiles and Domain Verification

The voice profile system is what keeps your automated posts from sounding like everyone else's automated posts. When you onboard a brand, the CLI analyzes sentence structure, vocabulary, formality level, and messaging themes. It stores that as a JSON profile you can version-control (because of course you're putting this in git).

You can also manually tweak profiles:

pking voice edit --brand yourcompany

That opens an editor where you can adjust tone sliders, add forbidden phrases, or specify topics to prioritize. Save it, and every future post reflects those changes.

Domain verification works the same way it does in the web app, but you trigger it from the terminal:

pking verify-domain --domain yourstartup.com

It returns a DNS record to add. Once verified, your posts can include links back to your site without getting flagged by spam filters.

Who This Is Actually For

If you're a solo founder running product, sales, and support, the CLI cuts marketing down to a maintenance task instead of a daily time sink. You can script your entire content calendar in a Sunday afternoon and forget about it until next month.

If you're running a small dev team at a SaaS company, this integrates into your CI/CD pipeline. You can auto-generate release notes posts every time you tag a new version. Or set up a cron job that reposts your top-performing blog content every quarter.

NGOs and non-profits often run on volunteer time. A CLI tool means the one person who knows how to code can set up automation that keeps social channels active without needing a dedicated marketing hire.

And if you're building AI agents (which a lot of people are in 2026, according to research from McKinsey's State of AI report), the CLI gives your agents a marketing arm. They can monitor product metrics, detect milestones, and auto-publish updates without human input.

What You Should Actually Do Next

Install the CLI from npm. Run the onboard command on your website. Generate 5 posts and see if they sound like you.

If they don't, edit the voice profile. If they do, schedule a month's worth of content and reclaim those hours.

The GitHub repo (here) includes full docs, example scripts, and a changelog. If you find a bug or want a feature, open an issue. We're shipping updates weekly.

Marketing automation shouldn't mean generic content. It should mean your actual brand voice, scaled across platforms, without the manual labor.

That's what we built. Go use it.
