getRecentPrioritizationFees

Read the recent Solana priority-fee floor over rpc edge to price compute-unit fees that land.

getRecentPrioritizationFees returns the per-compute-unit priority fees paid in recent slots. Use it to price your own compute-unit fee so your transaction lands during congestion without overpaying.

Request

Pass an optional array of account addresses to scope the sample to slots that touched those accounts; omit or pass [] for the network-wide floor.

curl -s https://rpc.rpcedge.com \
  -H 'content-type: application/json' \
  -H 'x-api-key: YOUR_UUID_KEY' \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getRecentPrioritizationFees",
    "params": [[]]
  }'

In Python, take a high percentile as your compute-unit price:

import requests
 
ENDPOINT = "https://rpc.rpcedge.com?key=YOUR_UUID_KEY"
 
fees = requests.post(ENDPOINT, json={
    "jsonrpc": "2.0", "id": 1,
    "method": "getRecentPrioritizationFees", "params": [[]],
}).json()["result"]
 
vals = sorted(f["prioritizationFee"] for f in fees)
p75 = vals[int(len(vals) * 0.75)]
print("suggested compute-unit price (micro-lamports/CU):", p75)

Parameters

Response

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": [
    { "slot": 429641440, "prioritizationFee": 0 },
    { "slot": 429641441, "prioritizationFee": 12000 }
  ]
}

Each element is one recent slot. prioritizationFee is in micro-lamports per compute unit (1 lamport = 1,000,000 micro-lamports). Take a high percentile (p75-p90) of the returned values as your compute-unit price, and set it with ComputeBudgetProgram.setComputeUnitPrice.
