Price with a loop

Moralis General
#1

Need to put in a loop that works

#2 

api_key = "5JMy60ThHmJWvS8kXnxJfNjrThMooHfW2IWsOSQA9ZfLh94g3Yryj8GR0NenQQ1f"
params = {
    "address": "0x2260fac5e5542a773aa44fbcfedf7c193bc2c599",
    "chain": "eth"
}

try:
    result = evm_api.token.get_token_price(
        api_key=api_key,
        params=params,
    )

    # Assuming that the API response is in JSON format with a "usdPrice" field
    usd_price = result.get("usdPrice")
    if usd_price:
        print(f"Bitcoin (USD): ${usd_price}")
    else:
        print("USD Price not found in the API response.")
except Exception as e:
    print(f"An error occurred: {e}")```

i want to add a loop bt i dont really kno how

#4

We have here an example of using loops for the price, you can check it and make your code similar to it
https://docs.moralis.io/web3-data-api/evm/how-to-get-historical-erc20-token-price?programming-language=python

#5

that makes a loop every 5 mins?

#6

You can also check our full video tutorial here - https://www.youtube.com/watch?v=B5tsTsIHOeo, which shows how to make the loops

#7

I’m using Python he uses js

#8

The logic will be same as in the tutorial you just have to add the similar loop logic in your python code.

Have a look at the solution on the below forum post on how to add timed loops in python.

#9

If I do that the rest of my files doesn’t load

#10

How does it affect your files?

#11

When that loop runs in that file it looks like it freezes the rest of the startup

#12

If you remove the loop does it work?

Try adding any prints to check if the expected code is running

#13

If I remove the loop it works and it does print the price with the loop

#14

Maybe you are calling the loop in an async function? If possible try making multiple parallel requests at once.

#15

Can I send my code and you can edit it

#16 

api_key = "API key"
params = {
    "address": "0x2260fac5e5542a773aa44fbcfedf7c193bc2c599",
    "chain": "eth"
}

try:
    result = evm_api.token.get_token_price(
        api_key=api_key,
        params=params,
    )

    # Assuming that the API response is in JSON format with a "usdPrice" field
    usd_price = result.get("usdPrice")
    if usd_price:
        print(f"Bitcoin (USD): ${usd_price}")
    else:
        print("USD Price not found in the API response.")
except Exception as e:
    print(f"An error occurred: {e}")```

Can u add a loop here and I’ll see if it works

#18

Here is an example code with loops. I used threading to run the loop in the background so it should not affect another part of your app.

from moralis import evm_api
import threading
import time

api_key = "API Key"
params = {"address": "0x2260fac5e5542a773aa44fbcfedf7c193bc2c599", "chain": "eth"}


# Separate the logic into a function to fetch the token price.
def get_token_price():
    try:
        result = evm_api.token.get_token_price(
            api_key=api_key,
            params=params,
        )

        usd_price = result.get("usdPrice")
        if usd_price:
            print(f"Bitcoin (USD): ${usd_price}")
        else:
            print("USD Price not found in the API response.")
    except Exception as e:
        print(f"An error occurred: {e}")


# Loop that runs in a separate thread.
def price_loop(stop_event):
    while not stop_event.is_set():
        get_token_price()
        time.sleep(5)  # Pause for 5 seconds before the next API call


# Function to start the lop
def start_loop():
    stop_event.clear()
    threading.Thread(target=price_loop, args=(stop_event,)).start()


# Function to stop the loop
def stop_loop():
    stop_event.set()

stop_event = threading.Event()

K Tks I’ll let u kno if it works I just need the change the api key right
