Crypto Historical Articles

The Historical Articles endpoint works like Crypto Articles but covers longer time windows — from 2 days up to 30 days back. Use it when you need to analyse trends, build charts, or backfill a dataset beyond the 24-hour window of the standard articles endpoint.

Use this to:

Build sentiment trend charts over the past week or month
Backfill a database with historical crypto news data
Compare how coverage of a coin or topic has evolved over time
Export large CSV datasets for offline analysis or ML training
