Step 1: Get storage pricing and payment options. Returns price breakdown and every available payment method (SOL/USDC/USDT/WETH/BETA on Solana, USDC/USDT0/MON/WETH on Monad). Each option carries a destination_kind: 'wallet' (native SOL — send lamports to pay_to_address), 'spl_token_account' (Solana SPL tokens — pay_to_address IS already the treasury's token account; pass it DIRECTLY as the transferChecked destination, do NOT derive an ATA from it), or 'evm_address' (Monad — send native value to the address, or call transfer() on the token contract at token_address). SPL options also include a self-contained spl_transfer block (program_id, destination_token_account, mint, amount_raw, decimals) you can pass straight to a signer. Review payment_options, pick one, then sign+submit externally and call nukez_pay with the resulting tx_sig. Providers: gcs (default), mongodb, storj, arweave, filecoin, firestore.
