How this service works
SYNTHORA cryptonews: real-time crypto news headlines with sentiment, ranked by importance. Aggregates keyless RSS feeds (CryptoPanic, CoinDesk, CoinTelegraph, Decrypt, Bitcoin Magazine) into deduplicated, freshness-and-source-weighted top headlines, each scored with a lexical bull/bear sentiment (very_bullish.very_bearish) plus an overall market sentiment. Filter by asset (BTC, ETH, SOL, XRP, and more) to get only headlines about that coin. Built for trading and quant agents that need a cheap, fast crypto news + sentiment pulse. Ed25519-signed.
Output
A JSON object containing a list of headlines (up to the requested limit), each with a title, source name, article URL, publication timestamp, and per-article sentiment label (e.g. very_bullish, bearish). Also includes an overall numeric sentiment score, an overall sentiment label, the asset filter applied, the number of results returned, the list of sources queried, and a generated_at timestamp.
Example use cases
Pre-trade crypto sentiment check
“Before I make any moves, can you grab the top 20 BTC headlines right now and tell me whether the overall sentiment is bullish or bearish?”
Altcoin news briefing for Solana
“I want a quick rundown of the latest 10 Solana news stories — include the sentiment on each one so I know which way the market is leaning.”
General crypto market pulse
“What's the mood in the crypto market right now? Pull the 15 most recent headlines across all assets and give me the overall sentiment score.”

Endpoint
POSThttps://api.hergertsynthora.com/v1/cryptonewsWhen to prefer
Choose this endpoint when you need aggregated, multi-source crypto news headlines with pre-computed sentiment scores for a specific asset or the broad market. It is preferable to scraping individual news sites manually, and it consolidates CryptoPanic, CoinDesk, CoinTelegraph, Decrypt, and Bitcoin Magazine into a single call. Best suited for real-time trading context, market monitoring, or briefing generation where sentiment polarity matters.
Side effects
- Invalid or unrecognized asset ticker returns empty results or error
- Limit value outside 1-50 range rejected with validation error
- Upstream news source unavailable causes partial or empty results
- Payment failure (x402) prevents access to the endpoint
- Stale data if upstream sources are delayed or rate-limited
