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

Official website
Source (CoinMarketCap)
Timestamp

Invalid or incomplete entries are automatically skipped.
