GET /agent/x402/cost/HYPE

unprobed

True cost of trading HYPE on Hyperliquid, measured on Vaunt's own IOC taker orders: slippage vs mid (p50/p90 bps), taker fee paid, wall-clock to fill, fill rate, against the venue-class median, plus spread, round-trip cost, depth within 1% and funding APR. Real fills, not quotes.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
