How this service works
Use before setting a priority fee. Gives prices in the exact unit Compute Budget expects (micro-lamports per compute unit) and the total cost in SOL, so you never overpay by a unit mistake. Turns recent on-chain priority fees into three price tiers and, when you pass your transaction, a compute limit and exact cost for each tier.
Output
Returns three fee tiers (e.g. low, medium, high) each expressed in micro-lamports per compute unit drawn from recent on-chain data. When a transaction is provided, also returns the estimated compute unit limit for that transaction and the exact total cost in SOL for each tier, enabling precise Compute Budget instruction construction without unit errors.
Example use cases
Setting fee before token transfer
“I'm about to send 50 USDC to a friend on Solana — what priority fee should I set right now? Give me the three tiers in micro-lamports per compute unit so I pick the right one without overpaying.”
Urgent NFT mint fee selection
“I need to get this NFT mint transaction confirmed ASAP — what's the current high-tier priority fee in micro-lamports per compute unit, and how much extra SOL will that actually cost me?”
Compute budget check for DeFi swap
“Before my agent signs this swap transaction, run it through the fee advisor to get the compute limit it needs plus the low, medium, and high priority fee options with their total SOL costs.”

Endpoint
POSThttps://solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/fee_advice?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when you need Solana priority fees expressed in the exact micro-lamports-per-compute-unit format that the Compute Budget program expects, avoiding unit-conversion mistakes. Prefer it over generic RPC calls when you want pre-tiered recommendations (low/medium/high) plus total SOL cost estimates in a single call, especially before signing any transaction in an automated agent workflow.
Side effects
- Invalid or malformed transaction bytes cause parsing failure
- Stale or unavailable on-chain fee data may result in less accurate tier estimates
- Missing required fields return a 400-level error
- RPC node connectivity issues may delay or block fee data retrieval
- If compute limit cannot be simulated, per-transaction cost estimates are omitted
