Make offer (build typed-data)

GET 
/v1/actions/midnight/make

MAKE — step 1 of 2. Build the EIP-712 typed-data for a limit offer at your own rate.

Morpho Midnight is an order-book lender — liquidity is a book of maker offers, not a pool — so there are two ways to interact:

• TAKE (fill existing offers): use the standard lending actions, which route to Midnight automatically for a MORPHO_MIDNIGHT_<id> market. There is no separate "take" endpoint.
  • lend → /v1/actions/lending/deposit — fills the ask side (supply offers)
  • borrow → /v1/actions/lending/borrow — fills the bid side (demand offers)
  • repay / withdraw → /v1/actions/lending/repay · /withdraw
  • Read the live two-sided ladder from /v1/data/lending/latest?includeOffers=true — each order-book market's loan leg carries offers (bids) and lendOffers (asks), best-first, with per-level aprPct, assets, and cumulativeAssets.
• MAKE (post your own limit offer at a chosen rate): the endpoints in this section (/v1/actions/midnight/*) plus /v1/data/lending/midnight/open-offers to list and cancel them.

Make flow (worker-assisted signing):

1. GET /v1/actions/midnight/make → returns typedData, the echoed inputs, and a one-time authorization tx.
2. The maker signs typedData with their wallet (wallet.signTypedData).
3. POST /v1/actions/midnight/finalize with { inputs, signature } → the on-chain transaction that publishes the offer to the Midnight mempool.

If authorization is present and the maker has not yet authorized the ratifier (read isAuthorized on-chain), send that one-time setIsAuthorized transaction before finalizing. The APR you request is snapped to an order-book tick — aprPctSnapped is the exact rate the offer will quote.
