{"name":"crypto-signal-scan","description":"Structured, informational signal brief for a token or crypto topic: X/Twitter sentiment, recent web coverage, and (when a fiat quote currency is supplied) a current exchange-rate reference, in one call. Composite: one call runs twitter-sentiment + search in parallel (both required together — the call only fails if both fail) plus exchange-rates as an optional third leg, since most crypto tickers aren't ECB-quoted fiat pairs. Data snapshot only: no trade signals, price targets, or investment recommendations. Use it as a crypto sentiment and news snapshot for agents tracking a token or topic across social and web sources.","price":"$0.05","method":"POST","input_schema":{"properties":{"topic":{"type":"string","description":"Token, ticker, or crypto topic to scan, e.g. 'ETH' or 'restaking'.
