# Cryptyx Asset Liquidity Depth

> Cryptyx Asset Liquidity Depth is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns order-book depth at 50, 100, and 200 basis points per crypto asset — bid/ask USD notional and imbalance ratio — aggregated from Binance spot books and refreshed every 15 minutes.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cryptyx-asset-liquidity-depth-e9c4c616
```

Example prompt: What's the current order book depth for BTC at 100 basis points — how much USD notional is sitting on the bid and ask sides, and is there any imbalance?

## When to prefer this

Use this endpoint when you need granular pre-trade liquidity data — specifically USD notional depth at multiple basis-point tiers — for slippage estimation or exchange routing decisions. Prefer it over generic ticker or price endpoints when the question is not 'what is the price?' but 'how much can I trade without moving the market?' Best suited for quantitative trading workflows, smart order routing, and position sizing checks on Binance-listed spot assets.

## Known failure modes

- Missing 'asset' query parameter returns an error or empty result
- Invalid or unsupported asset symbol (e.g. a delisted token) returns no data
- Stale data if Binance feed is temporarily unavailable (up to 15-minute refresh lag)
- Payment failure for the $0.01 USDC x402 fee returns 402 Payment Required
- Rate limiting if too many requests are made in rapid succession

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Per-asset spot order-book depth timeseries from api.asset_liquidity_timeseries_v1: ob_bid_50bp_usd, ob_ask_50bp_usd, ob_bid_100bp_usd, ob_ask_100bp_usd, ob_bid_200bp_usd, ob_ask_200bp_usd, plus spot_vol_1d_usd, spot_vol_7d_avg_usd, spot_vol_30d_avg_usd. Daily aggregate anchored to UTC−1, full history or trailing days window. Handler returns a bare JSON array of rows ordered by asof_day ASC; include=futures switches the envelope to {spot:[...], futures:{...}} where futures carries latest-day fut_ob_bid/ask_*bp_usd from compat.fut_ob_agg_1d_*. Use for pre-trade depth checks and venue routing across ~200 CRYPTYX-tracked assets.

## Output

Returns a JSON array under the 'liquidity' key containing per-asset records with bid and ask USD notional depth at 50, 100, and 200 basis points, plus an imbalance ratio indicating relative bid/ask skew, sourced from aggregated Binance spot books refreshed every 15 minutes.
