How this service works
Return timestamped Solana priority-fee quantiles for compute-unit bidding, optionally localized to up to 20 writable accounts. Designed for recurring transaction-bot polling at $0.002 per call.
Output
Returns a JSON object containing priority fee quantile data (e.g. p25, p50, p75, p95, p99 in microlamports) representing recent fee levels observed on the Solana network, optionally scoped to the specified writable accounts if provided.
Example use cases
Optimal fee for DeFi swap
“I'm about to submit a Solana swap transaction on Raydium — what priority fees are other transactions paying right now for the pool accounts So11111111111111111111111111111111111111112 and EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v so I can set a competitive compute unit price?”
Network-wide fee baseline check
“What are the current Solana priority fee quantiles across the whole network right now? I just need a baseline p50 and p95 to decide how aggressive to be with my fee.”
Landing urgent arbitrage transaction
“I need to land an arbitrage transaction on Solana ASAP — can you pull the priority fee distribution for accounts JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QsTayo and whirLbMiicVdio4qvUfM5KAg6Ekf9o5hErPkv4DPDWE so I know what fee will get me into the next block?”
Technical details
Endpoint
GEThttps://api.utilia.ink/base/v1/fees/priorityWhen to prefer
Use this endpoint when you need real-time, account-localized Solana priority fee estimates before submitting a transaction. It is especially valuable when interacting with high-traffic programs (e.g. DEX pools, lending protocols) where account-specific congestion differs from the network baseline. Prefer this over generic fee estimators when you have specific writable accounts and need quantile-level detail to choose a fee that balances cost and confirmation speed.
Side effects
- Invalid or malformed Solana account address returns a 400 error
- More than 20 accounts provided exceeds the limit and may return a validation error
- Payment not attached or insufficient USDC results in a 402 Payment Required response
- Network timeout if Solana RPC is congested
- Empty or stale fee data if no recent transactions reference the specified accounts
