Build a betting agent

Everything on this site is free to build on: the JSON feed, the OpenAPI spec, and an MCP server that now places paper orders by default and live ones only with your own key. The tutorials below go from "no account, fifteen minutes" to "a bot that grades itself". Each one is honest about what it cannot do: our own model currently scores worse than the T-6h market on the public ledger, and the tutorials teach you to measure that, not to hide it.

Reference

Which platforms allow agents

API, bot policy, fees, states, offers. Dated cells, ranked by suitability for an agent.

Where can an agent actually trade? Only where there is an API, and only the exchanges have one. See which platforms let an AI agent trade for you before you go live. Humans open accounts; agents trade. Never automate account creation or identity checks.

Disclosure: the Kalshi link is a partner link; we may earn a referral credit at no cost to you. 18+ on exchanges, 21+ at sportsbooks, state rules apply. Gambling problem? 1-800-GAMBLER. Paper first; the ledger, not the win rate, is the score.
