NEXUS oracle — Kalshi/Polymarket spread feed for pmxt agents

[RileyCraig14]

pmxt unifies prediction market APIs. NEXUS adds the Kalshi↔Polymarket cross-venue spread pmxt doesn't normalize today:

GET /kalshi?market=Fed          → free Kalshi odds
GET /arb/check?markets=Fed,BTC → paid spread + direction (22.75pt Fed live)
GET /probe                       → discovery manifest
MCP /mcp                         → agent tools

248+ bots already probing. Agentic Market validated x402 v2.

Custom data on request — any market, any schema, webhook feeds, RSS. We adapt to pmxt's adapter pattern.

If pmxt agents need spread data before placing orders, /arb/check is $0.02 USDC on Base. Free tier works without wallets.
