LunarCrush

LunarCrush is a real-time social intelligence platform for crypto, stocks, and trending topics. It aggregates billions of public posts from X (Twitter), Reddit, YouTube, TikTok, Instagram, and News across 4,000+ assets, runs them through topic classification, spam/bot filtering, sentiment scoring, and creator weighting, and turns them into proprietary metrics such as Galaxy Score, AltRank, TopicRank, CreatorRank, Social Dominance, and Sentiment. LunarCrush exposes this data through two developer surfaces: the LunarCrush API v4 (a REST API at lunarcrush.com/api4 for topics, categories, creators, posts, coins, stocks, and NFTs) and lunarcrush.ai (an AI/agent-native interface returning markdown/JSON/CSV, with a hosted Model Context Protocol server and a first-party CLI). Both use Bearer-token API-key authentication.

LunarCrush publishes 2 APIs on the APIs.io network. Tagged areas include Company, Social Intelligence, Cryptocurrency, Stocks, and Sentiment Analysis.

LunarCrush’s developer surface includes documentation, API reference, authentication, CLI, pricing, signup flow, engineering blog, and 15 more developer resources.
