​
repay_amount
default:0.01

Required range: x > 0
Example:

0.01

​
protocol
enum<string>
default:AAVE

Lending protocol to use. Defaults to Aave.

Available options:

string | null

Euler only: the EVK collateral vault to withdraw from. Required when protocol=EULER and withdrawing collateral.

​
sub_account_id
integer
default:0

Euler only: EVC sub-account (0–255) holding the debt to repay. Each sub-account is an independent Euler position with its own collateral, borrow controller, and health. Defaults to 0. Ignored for Aave/Morpho.

Required range: 0 <= x <= 255
​

boolean
default:false

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

Example:

false

​
permit2_signature
string | null

The EOA owner's signature of the Permit2 PermitTransferFrom typed data. When provided, the repay bundle will first pull repay_token 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
