Naive single-venue best execution for one crypto perpetual: the venue with the lowest precomputed slippage at your requested size. Excludes fees, funding and latency — a baseline to measure a router against, not a router.

Greedy multi-venue execution route for one crypto perpetual: walks venues in slippage order, allocating up to each venue's depth cap until size_usd is filled. Returns the route, total filled and blended slippage — how a large order splits across CEX and DEX venues. NAIVE: excludes fees.

Historical 24h-volume timeseries for one crypto perpetual on one venue, aggregated 1h/4h/1d — liquidity over time for backtests and venue selection. 30–90d window cap.

Cross-venue funding-rate spread for one crypto perpetual — the highest- and lowest-paying venues and the spread in bps, across major CEX and DEX perp venues (Binance, Bybit, OKX, Hyperliquid, Paradex, Drift …). The screen a funding-arb or basis desk starts from. `spread_bps` is the RAW rate difference — the same quantity, under the same name, as on `/v1/perp/arbitrage/funding`; `normalized_spread_8h_bps` scales both legs to 8h first — the comparable one, since venues quote on 1h/4h/8h. Leg intervals ship with the row; normalized is null when a schedule is unknown, never defaulted.

24-hour rolling USD volume for one crypto perpetual on one venue — liquidity and activity ranking across tracked CEX and DEX perp venues.

Why isn't my x402 listing getting discovered/sold? ?domain=you.com returns your Bazaar ranking inputs as cohort percentiles — last-30-day calls & unique payers, staleness, resource count, live health — so you can see where you sit vs the catalog. No args = cohort distribution + zero-call (invisible) listings. The visibility companion to listing-doctor. Descriptive percentiles, not a verdict.

Systemic reliability of x402 services grouped by shared hosting platform (workers.dev, vercel.app, fly.dev, onrender.com, run.app, trycloudflare.com …).
