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
