# Transfer internal USDC between Hyperliquid accounts

`POST /v1/trade/{venue}/usd-send`

## Request

- Base URL: `http://localhost:3200`
- URL: `http://localhost:3200/v1/trade/{venue}/usd-send`
- Auth: API key in header `X-Steward-Platform-Key`
- TypeScript: <https://skmtc.dev/steward-fi/apis/steward-api/docs/v1/trade/:venue/usd-send/post.ts> (a function with typed inputs; its response is checked against the schema)

Operator recovery endpoint. Auth deliberately accepts platform operators or tenant admins and must not require an agent JWT, so humans can recover funds when the agent token is expired. Raw signing keys never leave the vault; all recovery actions are audited and idempotency-protected. Platform-key only route that submits Hyperliquid's user-signed usdSend action for internal USDC transfers between Hyperliquid accounts. The transfer is signed by the sending agent's master Hyperliquid wallet.
