The Stellar Decentralized Exchange (SDEX) central-limit order book, live from the public Stellar Horizon API — no key, nothing cached. Where the pools reader covers Stellar's AMM and the asset reader covers token metadata, this surfaces the on-chain order book the others miss. Pull the live bids and asks for any asset pair with their price and amount, plus the derived best bid, best ask, mid price and spread. Get a compact ticker for a pair — best bid/ask, mid, spread and the last executed trade. And read the most recent executed trades, network-wide or filtered to a single pair, with their price and base/counter amounts. Defaults to the deeply-traded XLM/USDC pair; quote any pair by passing the selling and buying assets (asset code plus issuer, or XLM for native). The order-book-and-trading layer for Stellar wallets, swap UIs, market-makers and analytics. Live from horizon.stellar.org.

What a crypto trade actually costs once it eats into the order book — computed live from Binance's full depth feed (up to 5000 levels per side), no key, nothing stored. Top-of-book price is a fiction for anything but the smallest order: a real market order walks down the book, filling progressively worse levels, and the gap between the quoted price and the realised average fill is slippage. The estimate endpoint takes a pair, a side (buy or sell) and a size — in quote currency (notional, e.g. $250,000) or in base coin (quantity) — walks the live book level by level and returns the average fill price, the slippage versus the mid and versus top-of-book, the price impact (how far the last filled level sits from mid), the number of levels consumed and whether the book even holds enough liquidity to fill. The depth endpoint returns a liquidity profile: top bid/ask, mid, spread and the cumulative bid- and ask-side liquidity sitting within ±0.1%, ±0.25%, ±0.5%, ±1% and ±2% of mid, plus the book imbalance — a one-glance read on how deep and how lopsided a market is. The symbols endpoint lists tradable pairs. This is the execution-cost / market-impact analytics cut for crypto — distinct from the raw exchange order-book feed, from VWAP-on-candles, and from the price, ticker and quote APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form.
