required

Amount to borrow (in token units, not wei).

Required range: x > 0
Example:

50

​
token_in
string | null
default:USDC

A token identifier - either a supported symbol (e.g., USDC, WETH) or a valid Ethereum address (0x...)

Example:

"USDC"

​
amount_in
default:100

Amount of token_in to use (in token units, not wei). Omit together with token_in and collateral_token for borrow-only mode.

Required range: x > 0
Example:

100

​
collateral_token
string | null
default:USDC

A token identifier - either a supported symbol (e.g., USDC, WETH) or a valid Ethereum address (0x...)

Example:

"WETH"

​
interest_rate_mode
enum<string>
default:variable

The interest rate mode for the borrow position.

Available options:
stable,
variable
Example:

"variable"

​
slippage
default:0.5

Maximum slippage tolerance as a percentage (e.g., 0.5 = 0.5%). Only used when a swap is needed.

Required range: 0 <= x <= 100
Example:

0.5

​
gas_sponsorship
boolean
default:false

If true, returns EIP-712 signature data instead of an unsigned transaction.

​
permit2_signature
string | null

The EOA owner's signature of the Permit2 PermitTransferFrom typed data. When provided, the borrow bundle will first pull token_in from the owner's EOA into the Credit Account via Permit2. Obtain by calling /v2/credit/transfer and signing the returned EIP-712 data.

​
permit2_nonce
integer | null

The nonce used in the Permit2 signature (from the signed typed data).

Required range: x >= 0
​
permit2_deadline
integer | null

The deadline timestamp used in the Permit2 signature (from the signed typed data).

Required range: x >= 0
