# Building Better APIs

APIs are the backbone of modern software.
Here's how to design them right.

3. **Documentation** - Make it discoverable

What is OpenClaw?

OpenClaw is the open-source personal AI agent with 145k+ GitHub stars. It runs locally on your machine, connects through apps you already use, and takes real actions on your behalf.

💬

Works Where You Are

Message OpenClaw from WhatsApp, Telegram, Slack, Discord, Signal, iMessage, or 10+ other platforms. No new app to learn.

🧩

Skill-Based Architecture

OpenClaw extends its abilities through Skills — lightweight plugins defined in Markdown files. Postiz is available as a skill on ClawHub.

⏰

Proactive Automation

Schedule recurring tasks with cron jobs. OpenClaw can publish your Medium articles on a schedule without you having to ask each time.

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Medium articles with the right settings.

✓Install from ClawHub with one command: clawhub install nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Eligibility is checked automatically — POSTIZ_API_KEY must be set
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill
clawhub install nevo-david/postiz

# Or install the CLI globally
npm install -g postiz

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Verify OpenClaw sees it
openclaw skills list --eligible

# Output:
# - postiz: Social media automation
#   CLI for scheduling posts
#   across 30+ platforms

Medium Publishing with OpenClaw

Message OpenClaw from any platform — it reads the Postiz skill, discovers your Medium integration, and handles the entire publishing workflow autonomously.

🦀

From Any Chat App

WhatsApp, Telegram, Slack, Discord...

Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Medium account via Postiz, formats the article, and publishes it — all while you go about your day.

WhatsApp / Telegram

You: Publish my draft about API design
  to Medium under the engineering pub,
  tag it with "api" and "software"

OpenClaw: Got it! Here's what I'll do:
  1. Read your draft from ~/drafts/api.md
  2. Publish to your engineering publication
  3. Tags: API, Software Engineering

  Done! Your Medium article is live.
  Post ID: abc-123

Scheduled & Proactive

Cron jobs for recurring content

OpenClaw supports cron-based heartbeat tasks. Set up a recurring job that checks a folder for new Markdown drafts and publishes them to Medium automatically — no manual trigger needed.

openclaw.json (heartbeat)

{
  "heartbeat": [
    {
      "cron": "0 8 * * 1,3,5",
      "prompt": "Check ~/articles/pending
  for new .md files. For each one,
  extract the title from the first
  heading, publish to Medium with
  appropriate tags. Move published
  files to ~/articles/published."
    }
  ]
}

Why OpenClaw + Postiz for Medium

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Medium workflows.

✓Message from WhatsApp to publish a Medium article — no terminal needed
✓Cron jobs for hands-free weekly publishing schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Canonical URLs applied automatically when cross-posting from your blog
✓Cross-post to Medium + other platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Medium integration, formats your article, applies tags and publication settings, and publishes the post.

Claude Code

> Publish my API design article to Medium
  under the engineering publication with
  a canonical URL back to my blog

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "$(cat api-design.md)" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "Building Better APIs",
      "subtitle":"A practical guide",
      "canonical":"https://myblog.com/apis",
      "publication":"eng-pub-id",
      "tags":[...]}' \
    -i "medium-id"

Medium + Other Platforms

Publish the same article to Medium and other platforms in a single command. Each platform gets its own settings.

Terminal

# Cross-post an article to Medium and Dev.to
postiz posts:create \
  -c "$(cat article.md)" \
  -s "2025-03-01T09:00:00Z" \

      {"value": "software", "label": "Software"}
    ]
  }' \
