Cross-venue arbitrage opportunities from the Arb Bets feed
Server-side proxy to the Arb Bets vendor feed, called with a Kairos-held key so the credential never reaches a client. Fixed vendor parameters: $100 investment, 1.0% minimum profit. The body is the vendor’s payload passed through unchanged — Kairos does not normalize it, and its shape is owned by the vendor. Note the trailing slash: the route is registered at /arb-bets/, and /arb-bets redirects.
