# Exchange Live Orderbook

### GET /v1/exchange/orderbook — Exchange Live Orderbook

Returns the most recent L2 orderbook snapshot (full 20-level bids/asks) for Hyperliquid perpetual futures — BTC, ETH, SOL, XRP. Only rows from the last 60 seconds count as live; returns 404 "No recent data" otherwise (retry shortly). Scale and Enterprise tiers only (Free/Pro get 403).

**Query parameters**

| Name | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `format` | string | no | json | Response encoding. csv and tsv return the rows as a flat file instead of a JSON envelope — the envelope moves to X-* response headers and nulls render as \N. REQUIRES SCALE OR ENTERPRISE (json is available on every tier). Works with includebook=true — the bids/asks ladders come through as compact JSON inside their cell, complete and parseable (pandas: df["bids"].apply(json.loads)). |
| `exchange` | string | yes | — | Exchange identifier |
| `symbol` | string | yes | — | Perp symbol — all 7 collected coins |
