NythosX is the name of a full-stack developer's site (Joven Andrei Lagahit) that lists MCP servers named NythosX Market Data and NythosX Agent Tools 1, so it is the product the request names. For market data as a general tool, the established options are Alpha Vantage 3 and TickDB 2, which both offer REST and WebSocket market data APIs, with LastLook Data 4 as an agent-oriented alternative.
