Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Rizon is a paper-money exchange for horizon contracts: Higher or Lower on a number, paying a fixed 2× if it finishes on your side of the strike. The book quotes the strike, so every contract trades at 50/50 and the midpoint is the market's forecast. No real money is involved. Docs: https://rizon.markets/docs

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.
