Easy methods to pull cryptocurrency pricesHow to get historic ERC-20 token pricesHow to question pockets token balancesHow to get pockets token transfersHow to question ERC-20 metadata by contract
Nevertheless, earlier than leaping straight into the primary instance exhibiting you tips on how to pull cryptocurrency costs, we should maintain just a few conditions. These conditions are common for every of our examples. So, ensure that to cowl them earlier than persevering with!
Moralis Web3 Knowledge API with Python – Stipulations
Earlier than you progress, ensure that to have the next prepared:
Set up Python and PIP – Obtain and set up Python and PIP. Set Up Moralis – Join with Moralis and purchase your Web3 API key. When you register, you will discover your key by logging in and navigating to the ”Web3 APIs” tab:
Create a Python Undertaking – Create a brand new Python mission with an ”index.py” file. Set up the Moralis SDK by opening a brand new terminal and working the next command within the mission’s root folder: pip set up moralis
With the conditions coated, you at the moment are able to discover the varied Moralis Web3 Knowledge API endpoint. So, allow us to begin by overlaying how one can pull cryptocurrency costs with Python!
Easy methods to Pull Cryptocurrency Costs
When utilizing the Moralis Web3 Knowledge API and Python, all you want to pull cryptocurrency costs of ERC-20 tokens is a single name to the get_token_price() endpoint. So, open the ”index.py” file you created within the earlier part and add the next code snippet:
from moralis import evm_api
api_key = “YOUR_API_KEY”
params = {
“deal with”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”
}
end result = evm_api.token.get_token_price(
api_key=api_key,
params=params,
)
print(end result)
From right here, you want to make just a few minor configurations to the code. First, substitute YOUR_API_KEY with the Moralis API key you fetched when caring for the conditions. Subsequent, specify the chain and deal with parameters to suit your preferences.
That’s it; you must now be capable to run the script utilizing the next command:
python index.py
In return, you must end up with a response wanting one thing like this:
{
“nativePrice”: {
“worth”: “13753134139373781549”,
“decimals”: 18,
“title”: “Ether”,
“image”: “ETH”
},
“usdPrice”: 16115.165641767926,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,

}
Congratulations! It’s as straightforward as that to tug cryptocurrency costs when working with the Moralis Knowledge API and Python!
Get Historic ERC-20 Token Costs
Subsequent, we’ll look nearer at how one can question historic ERC-20 token costs with the Web3 Knowledge API and Python. To take action, we’ll use the identical get_token_price() endpoint; nevertheless, this time, you want to specify a spread and question one block at a time by means of a for loop. As such, you possibly can go forward and enter the next into the ”index.py” file:
from moralis import evm_api
api_key = “YOUR_API_KEY”
historicalPrice = []
for to_block in vary(16323500, 16323550, 10):
params = {
“deal with”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”,
“to_block”: to_block
}
end result = evm_api.token.get_token_price(
api_key=api_key,
params=params,
)
historicalPrice.append(end result)
print(historicalPrice)
This time, you want to substitute YOUR_API_KEY together with your Moralis key and specify the chain and deal with parameters, alongside together with your most well-liked vary. As soon as you might be achieved with these configurations, you possibly can as soon as once more run the script with the next terminal enter:
python index.py
In return, you get a response containing an array of various costs from varied cut-off dates. Right here is an instance containing two costs:
[
{
“nativePrice”: {
“value”: “642828540698243”,
“decimals”: 18,
“name”: “Ether”,
“symbol”: “ETH”
},
“usdPrice”: 0.7811524052648599,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,
“exchangeName”: “Uniswap v3”
},
{
“nativePrice”: {
“value”: “642828540698243”,
“decimals”: 18,
“name”: “Ether”,
“symbol”: “ETH”
},
“usdPrice”: 0.7811524052648599,
