This includes order IDs and timestamps for each order in the book. The Level3 endpoint requires authentication. **API Key Permissions Required:** `Orders and trades - Query open orders & trades` ## OpenAPI ````yaml /openapi/spot-rest.yaml post /private/Level3 openapi: 3.0.0 info: title: REST API version: 1.1.0 description: '' servers: - url: https://api.kraken.com/0 description: Production Server security: - API-Key: [] API-Sign: [] tags: - name: Market Data - name: Account Data - name: Trading - name: Funding - name: Subaccounts description: >- Subaccounts are currently only available to institutional clients.

It replaces the old `/staking` part of the API. The different available earn products are represented by earn strategies. This corresponds to the legacy `Staking/Assets`. `Stake`/`Unstake` are replaced by `Allocate`/`Deallocate`. ### Overview of the available endpoints under `/Earn`: - `Strategies` - list all earn strategies for which you are eligible or have a balance. - `Allocations` - lists the balance in your earn account for each strategy. Requires the `Query Funds` API key permission. - `Allocate`/`Deallocate` - allocate/deallocate to an earn strategy through an async operation. Requires the `Earn Funds` API key permission. - `AllocateStatus`/`DeallocateStatus` - verifies the state of the last allocation/deallocation. Requires the `Earn Funds` or `Query Funds` API key permission. ### Example usage: ### Determine which funds are earning rewards: 1. Call `Strategies` to obtain information about the relevant strategy. The `lock_type` field shows whether bonding/unbonding funds are earning yield. The relevant fields are `bonding_rewards`/`unbonding_rewards`. 2. Call `Allocations` for the relevant strategy. From the previous step, for strategies where bonding/unbonding does not earn yield, substract these balances from `amount_allocated.total` to determine which balances are currently earning. ### Get allocatable balance: Call `/0/private/BalanceEx`, subtract `hold_trading` amount. Remaining balance is available for allocation to a strategy. ### Geo restrictions: Some earn strategies are not available in all geographic regions. `Strategies` will return only strategies available to the caller. - name: Transparency paths: /private/Level3: post: tags: - Market Data summary: Query L3 Order Book description: > Retrieve Level3 order book data, which provides individual order information at each price level.
