MNX API
MNX is a derivatives exchange running on the MegaETH blockchain. This site documents its public REST API: 69 endpoints covering markets, order books, order placement, balances, positions, and candlestick data. The reference is generated directly from the exchange's API schema, so it always matches what the server actually accepts and returns.
