Discover, enrich & store cryptocurrency data with CoinMarketCap API

CoinMarketCap Token Discovery (Free API) Automatically discover cryptocurrency tokens from CoinMarketCap, clean the data, enrich it with official websites, and store the results in your preferred database or sheet. This workflow is designed to be safe for free API usage, easy to understand, and ready for extension. --- What This Workflow Does This workflow runs on a schedule and: 1. Randomly selects pages from CoinMarketCap listings 2. Fetches token data using the free CoinMarketCap API 3. Cleans and normalizes token fields 4. Enriches each token with official website data 5. Processes tokens in safe batches with delays 6. Outputs clean, structured token records 7. Optionally saves results to a database or sheet --- Who This Is For This workflow is useful if you are: - Doing crypto research or market discovery - Building token datasets - Running crypto outreach or lead generation - Learning how to work with APIs in n8n - Looking for a clean, real-world n8n example No advanced n8n knowledge is required. --- Setup Instructions (Required) Follow these steps before running the workflow: 1. Get a CoinMarketCap API Key - Create a free account on CoinMarketCap - Generate an API key from your dashboard 2. Add Your API Key - Open the HTTP Request nodes - Add your API key to the request headers: text X-CMCPROAPIKEY = YOURAPIKEY 3. Connect Storage Replace the storage node with your preferred option: - Google Sheets - Airtable - PostgreSQL - Webhook Add your own credentials before running the workflow. --- 4. Activate the Workflow - Enable the workflow - Let it run automatically based on the schedule --- How the Workflow Is Structured - Trigger: Runs every few days to avoid API limits - Random Page Generator: Prevents bias toward only top tokens - Batch Processing: Controls memory and request volume - Delay Logic: Keeps the workflow stable and API-friendly - Cleaning Steps: Removes messy or invalid data - Final Output: Clean, simple token records ready for use --- Output Example Each valid token produces a clean record like: - Token name - Symbol (ticker) - Official website - Source (CoinMarketCap) - Timestamp Invalid or incomplete entries are automatically skipped. --- Customization Ideas You can easily extend this workflow to: - Add social media scraping - Track new tokens over time - Trigger alerts for specific tokens - Combine with other crypto APIs - Feed data into outreach or analytics pipelines --- Important Notes - This workflow uses CoinMarketCap’s free API tier - Do not remove batch limits or delays unless you upgrade your API plan - Replace sample storage with your own before production use --- License This workflow is provided for educational and practical use. You are free to modify and adapt it for your own projects. --- Author Built and shared by Itunu Ola n8n automation builder focused on practical, production-ready workflows.
