# Get Off-Chain Snapshot

> Read depth, last price and 24-hour statistics for an off-chain book

Returns the same snapshot as [Get Order Book Snapshot](/endpoints/stock-trading/get-order-book-snapshot), served from the off-chain surface so a customer-facing integration does not need the Trading service entitlement.

Because an off-chain book holds no balance locks, its depth is not filtered on lock state: every `OPEN` or `PARTIALLY_FILLED` order that has not expired is counted.

This route does not assert the settlement mode, so it answers for on-chain books too. It also does not filter by token type.

## Path Parameters

<ParamField path="orderBookId" type="string" required>Order book ID.</ParamField>

## Query Parameters

<ParamField query="levels" type="integer" default="20">Price levels per side, capped at 100.</ParamField>

## Response Fields

Same shape as [Get Order Book Snapshot](/endpoints/stock-trading/get-order-book-snapshot): `orderBook`, `depth`, `lastPrice`, `priceReference`, `stats24h` and `timestamp`.
