GET /agent/x402/news-evidence

live

Live track record of Vaunt's news-driven lanes on Hyperliquid: per strategy, closed real-money trades, independent days, mean return per trade net of fees, win rate, median hold, realized USD. Not a backtest — an audited ledger of what a running engine actually booked.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
