Request the percentage of gas used for each block and extrapolate based on that.

curl -s https://mainnet.infura.io/v3/a9a11141e4e34d8fa95c5b5ddd37ea29 -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_feeHistory","params":[1, "latest", [100]],"id":1}' | jq

The type of params is [int, string, int[]]

We have decided to use etherscan API for EIP-1559 gas oracle so closing this one.
