How this service works
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. 0.001 USDC on Base. SYNTHORA.
Output
Returns a ranked, deduplicated list of crypto news headlines (up to 50), each with a lexical sentiment label (very_bullish, bullish, neutral, bearish, very_bearish), source attribution (CryptoPanic, CoinDesk, CoinTelegraph, Decrypt, Bitcoin Magazine), freshness/importance weighting, and an overall aggregate market sentiment signal. Response is Ed25519-signed for authenticity.
Example use cases
Example prompt

Technical details
Endpoint
POSThttps://cryptonews.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.001 USDC), real-time crypto news sentiment pulse aggregated from multiple authoritative sources without managing individual RSS feeds. Ideal for trading bots and quant agents that need a combined sentiment signal alongside headlines. Prefer over scraping individual news sites when you want deduplication, importance ranking, and a standardized bull/bear sentiment score in a single call.
Side effects
- Invalid asset ticker returns empty results or 400 error
- Limit out of range (must be 1–50) returns validation error
- RSS feed sources temporarily unavailable may yield stale or fewer headlines
- Insufficient USDC balance on Base causes payment failure and no response
- No headlines matching the requested asset filter returns empty list
