## Using the Priority Fee API

> [accordion] How do I improve the landing rate for my transactions with low fees?
>
> Use the [Priority Fee API](https://www.helius.dev/docs/priority-fee-api.md) to get optimal fee recommendations instead of guessing fees. Choose appropriate priority levels ("Medium" for most cases, "High" for time-sensitive operations) and follow transaction best practices.
>
> For paid plans, staked connections provide near-guaranteed delivery when combined with proper priority fees.
>
> See our [Transaction Optimization Guide](https://www.helius.dev/docs/sending-transactions/optimizing-transactions.md) for complete implementation details.

>
> Helius provides three main approaches:
>
> 1. **Smart Transactions** (Recommended) - Use our [SDKs](https://www.helius.dev/docs/sdks.md) for automatic optimization
> 2. **Manual Optimization** - Build and optimize transactions yourself with full control
> 3. **Ultra-Low Latency** - Use [Helius Sender](https://www.helius.dev/docs/sending-transactions/sender.md) for high-frequency trading
>
> See our [Sending Transactions Overview](https://www.helius.dev/docs/sending-transactions/overview.md) to choose the right method and [Manual Transaction Sending](https://www.helius.dev/docs/sending-transactions/send-manually.md) for step-by-step implementation.

> [accordion] What priority level should I use for my transactions?
>
> **Start with "Medium"** for most applications. Use "High" or "VeryHigh" for time-sensitive operations, and "Low" for cost-optimized non-urgent transactions.
>
> See the [Priority Fee API guide](https://www.helius.dev/docs/priority-fee-api.md) for detailed explanations of all six priority levels and when to use each.

> [accordion] How do I calculate the total cost of priority fees?
>
> **Formula**: Total priority fee = Price per compute unit × Compute units consumed
>
> Use the [Priority Fee API](https://www.helius.dev/docs/priority-fee-api.md) to get real time estimates for your specific transaction instead of manual calculations. The API accounts for current network conditions and transaction complexity.
