Exact Priority Fee lets traders specify a fixed fee in lamports. This fee will be used for every swap, regardless of network congestion.
To use Exact Priority Fee on the Create Swap endpoint, set the prioritizationFeeLamports parameter to your desired priority fee.To set an Exact Priority Fee using the Get Intent Quote endpoint, set the feeBudget parameter to your desired priority fee plus the base processing fee (10,000 lamports).
When using Get Intent Quote, remember to add the base processing fee (10,000 lamports) to your desired priority fee when setting feeBudget. Example: For a 5,000 lamport priority fee, set feeBudget to 15,000 lamports.

​
How It Works

  • The fee you specify will always be applied.
  • No automatic adjustments are made.
  • If the network requires higher fees, your swap may be delayed or fail.
The priority fee must always be at least 1 lamport; otherwise the swap will never be processed.
