How this service works
Morpho Midnight repay calldata (approve + repay debt units at face- units are loan-token atomic, 1:1 at maturity). POST /v1/tx/fixed/repay { marketId, assets (atomic face), owner }.
Output
Returns a structured object containing an array of transaction steps, each with 'to' (contract address), 'data' (encoded calldata), and 'value' (ETH value) fields, plus a 'network' identifier. Typically includes two steps: one ERC-20 approve and one repay call to the Morpho Midnight market contract.
Example use cases

Technical details
Endpoint
POSThttps://ozmium.org/v1/tx/fixed/repayWhen to prefer
Use this endpoint when you need to repay debt in a Morpho Midnight fixed-rate lending market and want pre-built, ready-to-sign approve + repay calldata. Prefer this over manually encoding calls when working with Morpho Midnight's face-value atomic units. Not appropriate for variable-rate Morpho Blue markets, Aave, or Compound repayments.
Side effects
- Missing or invalid marketId returns an error or empty steps
- Invalid owner address (non-checksummed or malformed) causes a 400-level error
- Assets value of zero or negative may be rejected
- Market ID not found in Morpho Midnight registry returns an error
- Insufficient on-chain balance at execution time (calldata is valid but tx will revert on-chain)
