description: Public (Public Holdings, Inc.) is a multi-asset investing platform where people can trade stocks, ETFs, options,
  index options, crypto, bonds, and treasuries, and hold IRAs, direct indexing, high-yield cash, and margin in one account.
  Public positions itself as an "agentic brokerage" and ships a public Trading API (api.public.com) that lets developers programmatically
  manage accounts, pull market data, and place equity, crypto, and options orders with commission-free execution and options
  rebates. It also operates a hosted, OAuth-secured MCP server (mcp.public.com) so AI assistants like Claude and ChatGPT can
  query portfolios and trade on a user's behalf, alongside an official Python SDK, command-line interface, and Postman collection.
  Backed by Accel.
