This document describes the Native Core business API. Clients submit signed trading actions with POST /trade and read business state with POST /info.

Operational, recovery, and node-private interfaces are intentionally not part of this contract.

Conventions

• API_URL examples use https://api-test.native.org.

• Hex values are 0x-prefixed lowercase strings unless noted otherwise.

• Protocol numeric fields in signed actions are decimal strings.

• Business query responses include query_height and app_hash when a query view is available. query_height is the execution height represented by the published read view.

• POST /trade returns admission success or rejection. Public clients confirm effects through business queries such as orderStatus, openOrders, userFills, userBalances, spotCreditPositions, spotCreditAccount, quoteAssets, oracleStatus, and markPrices.
