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.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/lunarcrush: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
