Bring your own bot. Keep your strategy.

Your bot sends Nevarn intents, never orders or keys. Decionis rules on each one. In shadow mode Nevarn records the ruling and sends nothing to a venue; with an execute key, your account's Sandbox fills it on paper and its Production places it live, only on an allow.

A first shadow ruling with nothing but curl, and what you can download.

  • Quickstart: your bot's first shadow ruling

    Create an account, mint an API key for your bot, and send one intent. Nevarn asks Decionis about it in shadow mode; nothing is sent to a venue.

Run
