Track A · Agent OS Mini Hackathon

Market evidence that argues against itself.

PayAna turns live Binance market data into a traceable briefing with explicit uncertainty, falsifiers and blind spots. The hosted analysis has no account access, no wallet authority and no trading endpoint; an optional user-initiated Agent OS OAuth flow verifies only the authorized MCP tool catalog and does not persist Binance tokens.

{SYMBOLS.map(s => )}

Permission boundary enforced

Public market analysis stays read-only. Optional Agent OS authorization is user-initiated, token-ephemeral and limited to catalog verification; no MCP tool is called automatically.
