● healthy a2a-agent

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.
