api.usenami.ioSized-depth quote for one crypto perpetual on ONE named venue: best bid/ask, depth per side, and est_slippage_for_size_usd_bps — the cost of filling size_usd here, in BASIS POINTS over the mid, not dollars. On a book deep enough to fill at the touch it equals half the spread and reads the same for $1K/$5K/$10K; on a thinner book it walks the ladder and grows with size. Equal values across sizes mean the book covers you, not that size_usd was ignored. All tracked venues: /v1/orderbook/multi-venue-slippage. $10K cap per DIS-022.

api.usenami.ioPer-venue basis for one crypto perpetual — mark versus index price, basis_bps = (mark−index)/index×10000, and contango/backwardation structure, across tracked CEX and DEX perp venues. Every venue comes with an index except Crypto.com, Variational and dYdX; dYdX publishes one oracle price, and that price is its mark. `venues_without_index` names the ones missing from your response. Each venue also carries liquidity_state (live/dead/unknown), and a market with no trading is flagged unreliable however clean its basis looks.

api.usenami.ioCross-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.

Outcome evidence starts with your workflow.

Private intake is ready for task IDs, charges, retries, result fingerprints and your evaluation criteria. Public performance comparisons need measured results; we do not have that benchmark yet.

Collection coverage

Discovery comes from configured registries. Endpoint checks record responses, not task success. Older snapshots retain less detail. Customer usage, commercial terms and task evaluations require additional evidence.

1,423 historical or current source records quarantined during normalization; they are excluded from public comparisons.

43 of 43 archive objects verified in Backblaze. Last verification: Sep 12, 2026, 05:56 UTC.
