Crypto Sources

The Sources endpoint returns the publishers that have actively posted articles in the last 24 hours. The list is dynamic — it reflects only sources with recent content, not a fixed registry. Use the identifiers returned here as the source parameter in Crypto Articles to filter results to a single publisher.

Weekend variation

Crypto news publishing slows down on weekends. Expect a smaller number of sources on Saturdays and Sundays compared to weekdays. Always fetch this list at query time (or cache it for a short window) rather than hardcoding source names, so your app stays accurate when the active set changes.
