Automated Blog Post Creation from News with AI and Blogger

This workflow automates the entire process of creating a fully SEO-optimized blog post from a news article. It fetches a trending technology news headline from Mediastack, generates relevant images from Pexels, uses two AI agents (via OpenRouter) to produce a title, slug, meta description, and a complete WordPress-compatible HTML blog post, then posts it directly to Blogger and sends you a Telegram notification. It's perfect for content marketers, bloggers, or anyone who wants to consistently publish fresh, data-driven content without manual effort.

Node Breakdown

• Schedule Trigger (No auth) — Runs the workflow at a set interval (configured every minute by default, but you should change it to daily or hourly).
• Mediastack News (API Key auth via query parameter) — Fetches the latest technology news article in English from the Mediastack API. Parameters: url set to https://api.mediastack.com/v1/news?categories=technology&limit=1&languages=en.
• Genarate image (API Key auth via header, httpHeaderAuth) — Searches Pexels for up to 2 images related to the news title. Parameters: query = {{ $json.data[0].title }}, per_page = 2.
• Send a text message1 (Telegram bot token auth) — Sends a Telegram message with the generated image URLs to the chat ID stored in $vars.telegramchatid.
• AI Agent (Uses OpenRouter Chat Model — API Key auth) — This agent takes the news title and returns a JSON object with three fields: slug, title, and meta (meta description). The prompt includes strict guidelines for SEO-friendly output.
• OpenRouter Chat Model (API Key auth) — The language model for the first AI agent, using microsoft/mai-ds-r1:free.
• Parsing (No auth) — A Code node that cleans the raw AI output (removes markdown code fences) and parses the JSON into usable fields.
• Copywriter AI Agent (Uses OpenRouter Chat Model2 — API Key auth) — This agent writes a complete 1,000-word SEO blog post in HTML format. It uses the title, meta, and the two images from Pexels. The prompt is very detailed, specifying structure, keyword placement, and styling.
• OpenRouter Chat Model2 (API Key auth) — Same model as the first, but used for the second agent.
• Cleanup HTML (No auth) — A Set node that removes any leftover ````html` or code fences from the AI output.
• HTTP Request (OAuth2 auth to Blogger) — Posts the cleaned HTML content to Blogger using the Blogger API v3. Parameters: url = https://www.googleapis.com/blogger/v3/blogs/$vars.bloggerid/posts, method POST, JSON body with title and content.
• Send a text message (Telegram bot token auth) — Sends a final Telegram notification confirming the blog post was created, including the title and a timestamp.

Setup Instructions

1. Mediastack — Sign up at mediastack.com to get a free API key. Create a new credential in n8n of type "Query Auth" (for httpQueryAuth) and enter your API key.
2. Pexels — Get a free API key from pexels.com/api. Create an n8n credential of type "Header Auth" and set the header name to Authorization and value to your API key.
3. OpenRouter — Register at openrouter.ai and generate an API key. Create an n8n credential of type "OpenRouter API".
4. Telegram — Create a Telegram bot via @BotFather and get the bot token. Set the chat ID (your user or group chat ID) as a workflow variable $vars.telegramchatid.
5. Blogger — Enable the Blogger API in Google Cloud Console, create OAuth2 credentials, and authorize n8n to access your blog. Obtain your blog ID and set it as $vars.bloggerid.
6. Adjust the Schedule Trigger to run at your desired frequency (e.g., daily at 9 AM) instead of every minute.

Use Cases & Variations

• Content Automation — Let the workflow run daily to automatically publish a new blog post based on the latest news. You can change the Mediastack category (e.g., business, sports) to match your niche.
• Multi-language Support — Modify the Mediastack query to fetch news in other languages, and adjust the AI prompts to write in that language.
• Custom Image Sources — Replace the Pexels node with another image API (e.g., Unsplash) or use a local image generation model.
• Different CMS — Swap the Blogger HTTP Request node with WordPress or any other CMS API (just change the URL and body format).
• Human-in-the-Loop — Add a Slack or email approval step before publishing to review the AI-generated content.
• Newsletter Integration — Instead of posting to a blog, send the formatted content as an email newsletter via Gmail or SendGrid.
