Web Scraping & Screenshot Automation
Convert natural language prompts into precise web searches using Firecrawl to scrape data and capture full-page screenshots.
What it does
You turn natural language requests into precise web searches that automatically scrape data and capture full-page screenshots using Firecrawl. You receive structured results with titles, links, content snippets, and images instantly without writing any code.
Step by step
- Configure the n8n HTTP Request node to call the Firecrawl scrape endpoint with the target URL and desired output format.
- Set up the OpenRouter API key in the environment variables of the n8n Chat Model node for authentication.
- Define a strict JSON schema in the LLM prompt template to ensure consistent output structure for titles, links, and snippets.
Where the LLM does the work
- Generate natural language search queries from vague user prompts by leveraging the OpenRouter model's reasoning capabilities.
- Filter and rank scraped content relevance based on the original user intent using few-shot examples in the prompt.
- Extract specific data points like prices or dates from unstructured HTML snippets returned by Firecrawl.
Watch out for
Full-page screenshots consume significant API credits and bandwidth, only request them for high-priority targets to manage costs effectively.
Dynamic content loaded via JavaScript might not appear in static HTML snippets, use Firecrawl's browser-based scraping mode for such sites.

You are helping me build the following AI agent workflow. ## Goal Web Scraping & Screenshot Automation: Convert natural language prompts into precise web searches using Firecrawl to scrape data and capture full-page screenshots. ## Specification - What it does: You turn natural language requests into precise web searches that automatically scrape data and capture full-page screenshots using Firecrawl. You receive structured results with titles, links, content snippets, and images instantly without writing any code. - Trigger: Run manually (Manual · on demand) - Autonomy: Fully hands-off - Expected setup effort: under an hour - Tools/services involved: - n8n: Workflow orchestration platform - Firecrawl: Web scraping and screenshot capture via API - OpenRouter Chat Model: Converting natural language to search queries ## Known pitfalls, handle each one explicitly in your implementation 1. Full-page screenshots consume significant API credits and bandwidth, only request them for high-priority targets to manage costs effectively. 2. Dynamic content loaded via JavaScript might not appear in static HTML snippets, use Firecrawl's browser-based scraping mode for such sites. ## Reference implementation https://n8n.io/workflows/6343 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Automation Platform than n8n?
Yes. n8n is only the example automation platform in this recipe. The same flow works with Home Assistant. Swap the automation platform connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for data analysts who want the pull-and-summarize grind automated.
Developers can adapt this to their own repo or ticket queue with the same trigger and tools.
