{"name":"crypto-news-brief","description":"Daily crypto news digest for a topic: today's headlines plus a structured research brief with overview, key facts, and recent news with source citations, in one call. Composite: one call runs search (day-recency headlines) as the required leg and research-brief in parallel as an optional leg, so a single scrape or LLM hiccup on the brief degrades the response instead of failing the call since the raw headlines already stand on their own. Use it as a daily crypto news roundup or topic digest for agents tracking a coin, protocol, or crypto theme.","price":"$0.03","method":"POST","input_schema":{"properties":{"topic":{"type":"string","description":"Crypto topic, coin, or protocol to digest, e.g. 'Solana' or 'stablecoin regulation'.
