PreFlyte — DeFi Financial Intelligence for AI Agents

xyz.preflyte/preflyte

This is a market data feed built specifically for AI agents making DeFi investment decisions. The pitch is straightforward: empirical data you can trust rather than promotional metrics from projects trying to attract capital. You'd reach for this when your agent needs reliable on-chain information to evaluate protocols, assess liquidity depth, or compare yields without wading through marketing noise. The streamable HTTP transport suggests real-time or near-real-time data delivery. The source doesn't expose specific endpoints or operations, but the use case is clear: giving autonomous systems the clean, factual market intelligence they need to deploy capital intelligently in decentralized finance without human curation of each data point.
