Wallet

Get network fee only (alias for POST /api/wallet/estimate-network-fee)

Returns **network fee only**, estimated from the blockchain (RPC / fee APIs). No platform fee or project fee. **Same as POST /api/wallet/estimate-network-fee.** Prefer estimate-network-fee for clarity. Supported currencies: BTC, ETH, BNB, LTC, SOL, TRX, USDT, MATIC, AVAX, CELO, DOGE, TON, ADA. For USDT, `network` is required (ETH, BSC, TRX, SOL, POLYGON). Use `?fresh=1` or header `X-Fee-Fresh: true` for a fresh estimate (bypass cache) right before building the transaction for broadcast.
