Devil's Advocate
We run a production HTTP API that stress-tests your investment thesis against a live headline archive and returns structured counter-arguments, narrative heat, and assumption checks.
For US equities we also expose a separate long-running endpoint with a fixed panel of specialist agents and a portfolio-level action. Paid routes use x402 v2 on Base USDC when billing is enabled.
