Returns an unsigned Solana transaction from DFlow. The agent signs it locally and submits via POST /kalshi/submit. Your private key never leaves your machine.

​
Notes

  • Supports both agent and UI flows.
  • BUY requires KYC when userPublicKey is provided.
  • When BUY and userPublicKey is missing, server returns previewOnly=true for quote preview.
  • Response is raw JSON (not wrapped by global ApiResponse interceptor).
