# @FeeSaver\_bot
The Telegram bot is the main interface for purchasing energy and bandwidth.
Go to the bot [t.me/FeeSaver\_bot](https://t.me/FeeSaver_bot) and press **/start**. After that you will be registered in the system, a deposit address will be assigned to you and all services will become available.
[Energy](/docs/feesaver/buy-energy.md) - you can buy from 32,000 to 5,000,000 energy per order
[Bandwidth](/docs/feesaver/buying-bandwidth.md) - purchase bandwidth from 350 to 300,000 units
[Smart Mode](/docs/feesaver/smart-mode.md) - the address connected to smart mode will always maintain a level of **131,000 energy**
[Instant Purchase](/docs/feesaver/instant-purchase.md) - purchase via TRX transfer. Send TRX to the address and in the next transaction you will receive energy
[AutoRefill](/docs/feesaver/auto-refill.md) - automatic replenishment of energy by a set amount when the specified threshold is reached. In settings set the rule: refill **200,000 energy** when its level falls below **500 000**
Unlimited rental - energy **is purchased for 24 hours**, after that time a reclaim is performed and new energy is delegated, so the energy remains on your address at all times until the mode is turned off or the balance runs out
