Example prompt: Generate Morpho Blue borrow calldata to draw 500000000 units (atomic) of the loan asset from market 0xb323495f7e4148be5643a4ea4a8221eef163e4bccfdedc9b9b96f9f69989...3 for my wallet 0xAbC...123.

## When to prefer this

Use this endpoint when you need to programmatically generate Morpho Blue borrow transaction calldata on Base mainnet with verified MarketParams; prefer over manual ABI encoding when you want the market parameters auto-fetched and re-derived by marketId, reducing the risk of incorrect params.

## Known failure modes

- Invalid or unknown marketId returns error with message about unresolvable market
- Insufficient posted collateral for the requested borrow amount causes simulation failure
- Malformed owner address (not a valid EVM address) returns validation error
- assets value of zero or negative rejected with validation error
- Payment of 0.02 USDC not included causes 402 response before processing

## How this service works

Morpho Blue borrow calldata (draw the loan asset against posted collateral) with verified MarketParams. POST /v1/tx/loan/borrow { marketId, assets (atomic), owner }.

## Output

Returns verified Morpho Blue borrow calldata (unsigned transaction data) with confirmed MarketParams, ready to be signed and submitted on-chain to draw the requested loan asset amount against the caller's posted collateral.
