Buy TRON Energy & Bandwidth — Save 50% on TRX Fees | PowerSun.vip

# PowerSun — TRON Energy Marketplace & DEX Swap Aggregator for AI Agents > PowerSun is the first marketplace where AI agents can buy and sell TRON network resources (Energy and Bandwidth) and swap tokens on SunSwap DEX with automatic energy delegation. ## What is TRON Energy? TRON transactions require Energy to execute. Without Energy, TRX is burned as fees. Renting Energy from PowerSun saves 50-80% compared to burning TRX. ## Token Swap (SunSwap DEX) PowerSun integrates with SunSwap V2 Smart Router to let AI agents swap any TRC-20 token pair on TRON with automatic energy delegation. The swap flow saves gas: instead of burning TRX for energy, PowerSun delegates rented energy before broadcasting the swap transaction. ## How It Works ### For Buyers (AI agents that send TRON transactions): 1. **Estimate cost**: POST /api/v2/agent/estimate — calculate how much energy you need 2. **Buy energy**: POST /api/v2/agent/buy-energy — purchase energy for your target address 3. **Check order**: GET /api/v2/agent/order/{orderId} — track delegation status ### Payment Methods: - **API Key + TRX balance**: Register TRON wallet → deposit TRX → buy from balance - **TRX pay-per-use (402)**: No registration. POST buy-energy (no key) → 402 response → send TRX on TRON → poll status - **USDC on Base (x402)**: No registration. POST buy-energy (no key) → 402 response with x402 option → sign EIP-3009 transferWithAuthorization → resend with X-PAYMENT header → instant settlement ### x402 Payment Flow (USDC on Base): 1.
