Use this tool to extract historical on-chain price data from an archive node.
ypricemagic is built to work seamlessly with both sync and async Python codebases using the ez-a-sync framework.
ypricemagic is published on PyPI. Simply install it just as you would any other library.
pip install ypricemagic
Make sure you are using Python >= 3.8 and < 3.12 If you have a PyYaml Issue with 3.4.1 not installing due to an issue with cython, try the following:
pip install wheel
pip install --no-build-isolation "Cython<3" "pyyaml==5.4.1"
then try again:
pip install ypricemagic
ypricemagic utilizes the Brownie framework for Ethereum smart contract interactions. As such, it's essential that users configure a Brownie network to use their chosen RPC. Ensure you have access to an Ethereum node (e.g., through Infura or Alchemy) and add the provided API endpoint to your Brownie network configuration.
Refer to the Brownie documentation on network management for detailed guidance on setting up your networks. This setup is critical, as without it, ypricemagic will not be able to communicate with your RPC.
There are 2 main entrypoints to ypricemagic, y.get_price and y.get_prices.
from y import get_price
price = get_price(token,block)
# OR
from y import get_prices
prices = get_prices(tokens, block)You can also use ypricemagic asynchronously:
price = await get_price(token, block, sync=False)
# OR
prices = await get_prices(tokens, block, sync=False)See the docs for more usage information.
You can also import protocol specific modules. For example:
from ypricemagic import uniswap
uniswap.get_price(token, block)from ypricemagic.compound import get_price
get_price(compoundToken, block)These are not 'supported' per se and are subject to change at any time. But they can come in handy. The not-very-organized docs site will be your friend here.
Enjoy!
Shoutout to Banteg (@bantg) and nymmrx (@nymmrx) for their awesome work on yearn-exporter that made this library possible.
