How this service works
Solana priority fee estimator: recent per-slot priority fees (min, median, p75, p90, max micro-lamports per CU) and total cost in SOL for a 200k-CU transaction.
Output
Returns a JSON object with: the Solana network name, a note, the number of slots analyzed, the reference accounts used, a breakdown of micro-lamports per compute unit at min/median/p75/p90/max percentiles, and estimated total SOL cost for a 200k-CU transaction at median/p75/p90 and without any priority fee.
Example use cases
Optimizing Solana swap transaction fees
“I'm about to submit a Jupiter swap — what priority fee should I set? Give me the current p75 and p90 micro-lamports per CU on Solana so I can choose the right level without overpaying.”
Monitoring Solana network congestion
“Is the Solana network congested right now? Pull the latest priority fee stats across all percentiles for Raydium accounts and tell me how much a 200k-CU transaction would cost in SOL at the median and p90 levels.”
DeFi bot fee calibration
“For my Solana trading bot, I need the recent priority fee distribution — min, median, p75, p90, and max in micro-lamports per CU — so I can dynamically set fees. Use Jupiter and Raydium as the reference accounts.”
