POST/api/public/v1/tx/send

Send transaction (buy · sell · create launch)

Sign and broadcast any transaction from your custodial wallet. This one endpoint powers buy, sell, and create-launch — encode the calldata for the Noxa router / factory and pass it as `data`. Convenience wrappers (/trade, /launch/create) ship once the Noxa ABI is finalized; until then this is the direct path bots are already using.

Parameters

Name	Type	Description
`to`required	`address`	Target contract (Noxa router for buy/sell, factory for launch)
`data`	`hex`	Encoded calldata (0x-prefixed). Omit for a plain ETH transfer.
`value`	`wei string`	ETH to attach in wei. Required for buys.
`gas`	`string?`	Optional gas limit override

Request
