{"name":"x-kol-sentiment","description":"KOL sentiment API: send a topic and get back a follower-weighted sentiment read across recent X/Twitter posts from accounts big enough to move opinion, not noise accounts. Composite: one call runs tweet-search over a large page, filters to authors above a follower bar, scores each qualifying post with a deterministic lexicon, and rolls the scores into one follower-weighted number, then runs an optional sentiment-analysis LLM pass over the same text as corroboration. tweet-search is required; the LLM leg degrades the response instead of failing the call, since the weighted score comes from the local scorer either way. Use it as a KOL sentiment tracker, influencer sentiment API, or follower-weighted social sentiment tool for agents gauging how a topic lands with accounts that matter.","price":"$0.05","method":"POST","input_schema":{"properties":{"topic":{"type":"string","description":"Topic, brand, ticker, or phrase to gauge sentiment on, e.g. 'x402 payments'.
