SimulationBody

Request body for POST variants of action endpoints. Provides the current portfolio state so the API can project post-trade metrics. All fields (balanceData, aprData, positions) are returned by the user-data endpoints — pass them through directly without modification.

balanceData objectrequired

Aggregated balance data for a sub-account.

depositsnumber

Total deposits in USD

Example: 10000.5

debtnumber

Total debt in USD

Example: 5000.25

adjustedDebtnumber

Debt adjusted for borrow factors

Example: 5500

collateralnumber

Collateral value in USD

Example: 9000

collateralAllActivenumber

Collateral if all assets were enabled

Example: 10000.5

borrowDiscountedCollateralnumber

Collateral discounted by borrow factors

Example: 8000

borrowDiscountedCollateralAllActivenumber

Discounted collateral if all enabled

Example: 9000

navnumber

Net asset value (deposits - debt)

Example: 5000.25

deposits24hnumber

Deposits 24h ago (for change calculation)

Example: 9800

debt24hnumber

Debt 24h ago

Example: 4900

nav24hnumber

NAV 24h ago

Example: 4900

rewards object

Pending rewards by token

property name*any

Pending rewards by token

aprData objectrequired

APR breakdown for a sub-account.

aprnumber

Net APR (deposit - borrow)

Example: 2.5

depositAprnumber

Weighted deposit APR

Example: 3.5

borrowAprnumber

Weighted borrow APR

Example: 5.2

rewardAprnumber

Total reward APR

Example: 1.2

rewardDepositAprnumber

Reward APR on deposits

Example: 0.8

rewardBorrowAprnumber

Reward APR on borrows

Example: 0.4

intrinsicAprnumber

Intrinsic yield APR (e.g., stETH staking)

Example: 0

intrinsicDepositAprnumber

Intrinsic yield APR portion from deposits

Example: 0

intrinsicBorrowAprnumber

Intrinsic yield APR portion from borrows

Example: 0

rewards object

Reward token details

property name*any

Reward token details

modeIdstring

Mode/config key (defaults to "0")

Example: 0

positions object[]

Current lending positions for the relevant lender sub-account. Use the positions array from the user-data endpoint response (items[].positions). Always include this field for accurate simulation — the API uses it to compute collateral adjustments across all markets.

Array [

marketUidstringrequired

Unique market identifier (format: {lender}:{chainId}:{address})

Example: AAVE_V3:1:0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2

depositsUSDnumberrequired

Deposit amount in USD

Example: 5000
