**APIs profiled:** 9

Forum is a centralized exchange offering exposure to engagement-backed assets — "the first exchange to trade on attention." It turns online attention across social, search, and streaming data into measurable, tradable attention indices, then lists continuous perpetual-style futures contracts on top of them so participants can go long or short on cultural relevance as a new asset class. Forum (Y Combinator W26, based in New York City) exposes a full public developer surface: an OpenAPI 3.1 REST API at api.forum.market/v1 for market data, order management, positions, and account queries, and an AsyncAPI 3.0 WebSocket feed at wss://api.forum.market/ws/v1 for real-time order book, ticker, trade, index, and funding updates. Authentication is HMAC-SHA256 request signing with read/trade API-key permissions, and the docs ship an agent-native discovery surface (llms.txt, agent-card, agent-skills, and a documentation MCP server).
