How this service works
Priority fee estimates for Solana transactions
Output
Returns priority fee estimates (compute unit prices) for Solana transactions — either globally across the network or scoped to a specific program like Jupiter, helping callers set appropriate fees to ensure timely transaction confirmation.
Example use cases
Example prompt
“What priority fee should I use for a Jupiter swap on Solana right now? Use the program ID JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QNyVTaV4.”
Technical details
Endpoint
GEThttps://solana-fees.api.klymax402.com/api/feesWhen to prefer
Use this endpoint when building Solana transaction submission flows that need dynamic priority fee recommendations, especially when targeting specific programs like Jupiter, Raydium, or other DeFi protocols where program-specific fees differ from global averages.
Side effects
- Invalid or unrecognized program ID returns an error or falls back to global fees
- Network congestion data unavailable leads to stale or missing estimates
- Rate limiting or payment failure (402) if USDC payment is not included
- Malformed query parameters may return a 400 bad request
