Python API for Cryptocurrency – Get Crypto Knowledge
Within the following sections, we’ll dive deeper into how you should utilize the Web3 API to get cryptocurrency information with Python. In doing so, we’ll discover 5 distinguished examples:
How you can 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
Nonetheless, earlier than leaping straight into the primary instance displaying you the way to pull cryptocurrency costs, we should deal with 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 – Conditions
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 – Enroll with Moralis and purchase your Web3 API key. When you register, yow will discover your key by logging in and navigating to the ”Web3 APIs” tab:
Create a Python Venture – Create a brand new Python venture with an ”index.py” file. Set up the Moralis SDK by opening a brand new terminal and working the next command within the venture’s root folder: pip set up moralis
With the conditions lined, 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!
How you can Pull Cryptocurrency Costs
When utilizing the Moralis Web3 Knowledge API and Python, all it’s worthwhile 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 = {
“tackle”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”
}
end result = evm_api.token.get_token_price(
api_key=api_key,
params=params,
)
print(end result)
From right here, it’s worthwhile to make just a few minor configurations to the code. First, change YOUR_API_KEY with the Moralis API key you fetched when taking good care of the conditions. Subsequent, specify the chain and tackle parameters to suit your preferences.
That’s it; you need to now be capable to run the script utilizing the next command:
python index.py
In return, you need to end up with a response wanting one thing like this:
{
“nativePrice”: {
“worth”: “13753134139373781549”,
“decimals”: 18,
“title”: “Ether”,
“image”: “ETH”
},
“usdPrice”: 16115.165641767926,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,
“exchangeName”: “Uniswap v3”
}
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, it’s worthwhile to specify a spread and question one block at a time by way of a for loop. As such, you may 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 = {
“tackle”: “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, it’s worthwhile to change YOUR_API_KEY together with your Moralis key and specify the chain and tackle parameters, alongside together with your most well-liked vary. As soon as you might be finished with these configurations, you may 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 numerous deadlines. 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,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,
“exchangeName”: “Uniswap v3”
},
]
How you can Question Pockets Token Balances
For the third instance, we’ll present you the way to question pockets token balances. To get this info, we’ll make an API name to the get_wallet_token_balances() endpoint. As such, copy the snippet beneath and enter the code into your ”index.py” file:
from moralis import evm_api
api_key = “YOUR_API_KEY”
params = {
“tackle”: “0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d”,
“chain”: “eth”,
}
end result = evm_api.token.get_wallet_token_balances(
api_key=api_key,
params=params,
)
print(end result)
You may observe the identical sample right here and add your Moralis API key by changing YOUR_API_KEY. Subsequent, modify the tackle and chain parameters to suit your improvement wants. From there, all that continues to be is working the code with the identical terminal enter:
python index.py
In return, that is what the response ought to seem like:
[
{
“token_address”: “0xefd6c64533602ac55ab64442307f6fe2c9307305”,
“name”: “APE”,
“symbol”: “APE”,

“decimals”: 18,
“balance”: “85000000000000000”
}
]
How you can Get Pockets Token Transfers
Subsequent, allow us to present you the way to get pockets token transfers. Getting this information is straightforward when working with the Moralis Web3 Knowledge API and Python. In reality, all you want is a single API name to the get_wallet_token_transfers() endpoint:
from moralis import evm_api
api_key = “YOUR_API_KEY”
params = {
“tackle”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”
}
end result = evm_api.token.get_wallet_token_transfers(
api_key=api_key,
params=params,
)
print(end result)
When you add the snippet above to your ”index.py” file, you will need to alter the code by including your API key and configuring the parameters to suit your wants. You may then run the script with the command beneath:
python index.py
If you run the code, you need to end up with a response much like the one proven beneath in your terminal:
{
“whole”: 126,
“web page”: 0,
“page_size”: 100,
“cursor”: “eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhZGRyZXNzIjoiMHgyMjYwZmFjNWU1NTQyYTc3M2FhNDRmYmNmZWRmN2MxOTNiYzJjNTk5IiwiY2hhaW4iOiJldGgiLCJhcGlLZXlJZCI6MTkwNjU5LCJsaW1pdCI6MTAwLCJ0b3BpYzMiOiI9Om51bGwiLCJ0b19ibG9jayI6IjExMTAwMDQ1IiwicGFnZSI6MSwidG90YWwiOjEyNiwib2Zmc2V0IjoxLCJ1YyI6dHJ1ZSwiaWF0IjoxNjY5NjQ2ODMzfQ.NIWg35DjoTMlaE6JaoJld24p9zBgGL56Zp8PPzQnJk4”,

“value”: “4489517”,
“transaction_index”: 48,
“log_index”: 66
}
]
}
How you can Question ERC-20 Metadata by Contract
For our final instance of how you should utilize the Moralis Web3 Knowledge API with Python, we’ll present you the way to question ERC-20 metadata based mostly on a contract tackle. To get this information, Moralis offers you with the get_token_metadata() endpoint. To name this endpoint, enter the next code into your ”index.py” file:
from moralis import evm_api
api_key = “YOUR_API_KEY”
params = {
“addresses”: [“0x1f9840a85d5af5bf1d1762f925bdaddc4201f984”],
“chain”: “eth”
}
end result = evm_api.token.get_token_metadata(
api_key=api_key,
params=params,
)
print(end result)
Subsequent, swap out YOUR_API_KEY on your Moralis Web3 API key. From there, acquire the contract tackle you need to question and change the parameters accordingly. You may then run the script by inputting python index.py into your terminal and hitting enter.
Consequently, you need to obtain a JSON response much like this:
[
