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 outstanding examples: 

The best way 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

Nonetheless, earlier than leaping straight into the primary instance displaying you tips on how to pull cryptocurrency costs, we should maintain a couple of conditions. These conditions are common for every of our examples. So, ensure to cowl them earlier than persevering with! 

Moralis Web3 Knowledge API with Python – Stipulations

Earlier than you progress, ensure 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, you’ll find your key by logging in and navigating to the ”Web3 APIs” tab:

Create a Python Mission – Create a brand new Python challenge with an ”index.py” file. Set up the Moralis SDK by opening a brand new terminal and operating the next command within the challenge’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 masking how one can pull cryptocurrency costs with Python!

The best way to Pull Cryptocurrency Costs 

When utilizing the Moralis Web3 Knowledge API and Python, all you must 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 = {
“handle”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”
}

outcome = evm_api.token.get_token_price(
api_key=api_key,
params=params,
)

print(outcome)

From right here, you must make a couple of 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 handle parameters to suit your preferences.

That’s it; it is best to now be capable of run the script utilizing the next command: 

python index.py

In return, it is best to end up with a response wanting one thing like this: 

{
“nativePrice”: {
“worth”: “13753134139373781549”,
“decimals”: 18,
“identify”: “Ether”,
“image”: “ETH”
},
“usdPrice”: 16115.165641767926,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,
“exchangeName”: “Uniswap v3”
}

Congratulations! It’s as simple 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; nonetheless, this time, you must specify a spread and question one block at a time by 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 = {
“handle”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”,
“to_block”: to_block
}
outcome = evm_api.token.get_token_price(
api_key=api_key,
params=params,
)

historicalPrice.append(outcome)

print(historicalPrice)

This time, you must change YOUR_API_KEY together with your Moralis key and specify the chain and handle parameters, alongside together with your most well-liked vary. As soon as you might be achieved 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 varied closing 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,
“exchangeAddress”: “0x1f98431c8ad98523631ae4a59f267346ea31f984”,
“exchangeName”: “Uniswap v3”
},
]

The best way to Question Pockets Token Balances 

For the third instance, we’ll present you tips on how 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 = {
“handle”: “0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d”,
“chain”: “eth”,
}

outcome = evm_api.token.get_wallet_token_balances(
api_key=api_key,
params=params,
)

print(outcome)

You’ll be able to observe the identical sample right here and add your Moralis API key by changing YOUR_API_KEY. Subsequent, modify the handle and chain parameters to suit your improvement wants. From there, all that continues to be is operating the code with the identical terminal enter: 

python index.py

In return, that is what the response ought to appear to be: 

[
{
“token_address”: “0xefd6c64533602ac55ab64442307f6fe2c9307305”,
“name”: “APE”,
“symbol”: “APE”,

The best way to Get Pockets Token Transfers 

Subsequent, allow us to present you tips on how to get pockets token transfers. Getting this information is easy when working with the Moralis Web3 Knowledge API and Python. The truth is, 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 = {
“handle”: “0x2260fac5e5542a773aa44fbcfedf7c193bc2c599”,
“chain”: “eth”
}

outcome = evm_api.token.get_wallet_token_transfers(
api_key=api_key,
params=params,
)

print(outcome)

When you add the snippet above to your ”index.py” file, you should alter the code by including your API key and configuring the parameters to suit your wants. You’ll be able to then run the script with the command beneath: 

python index.py

Whenever you run the code, it is best to end up with a response just like the one proven beneath in your terminal: 

{
“complete”: 126,
“web page”: 0,
“page_size”: 100,
