Where every order finds its match.

A small stock exchange that pairs your buy and sell orders the instant their prices meet.

The platform

Everything a broker needs

A full trading surface, from the dashboard or the API.

  1. 01

    Order matching

    Best price first, then first in line. Big orders fill in pieces.

  2. 02

    Live market data

    A live order book and price for every symbol.

  3. 03

    Settlement & webhooks

    Cash and shares settle at once, with a webhook on every fill.

For developers

Built to build on

A clean REST API over a matching engine you can actually reason about.

  • Place a buy or sell order, get an id back.
  • Get a signed webhook on every fill.
  • Drive it all from an LLM over MCP.
