A list of recent altcoin news items from CoinDesk RSS, each containing a title, a short summary, and a link to the full article.

Technical details
Endpoint
GEThttps://finance-api.kdlcfa.workers.dev/altcoin-newsWhen to prefer
Choose this endpoint when you need a quick, pre-filtered altcoin news digest from CoinDesk without building your own RSS parsing or keyword filtering. It is ideal for agents that need timely altcoin headlines for the seven major coins listed, and want to avoid irrelevant Bitcoin/Ethereum-only stories. Prefer it over general crypto news endpoints when the user's focus is specifically on altcoins.
Side effects
- CoinDesk RSS feed unavailable — returns empty or error response
- No matching altcoin stories in the current RSS window — returns empty list
- Rate limit or payment failure — 402 response requiring USDC payment
- Cloudflare Worker timeout if upstream RSS is slow
