Near-data-fetcher

This Python script fetches block height data from specified NEAR RPC endpoints. It makes repeated requests to the endpoints, logs the responses, and includes a timestamp for each request.

Prerequisites Ensure you have Python and the requests package installed on your system.

Install Python If Python is not already installed, you can install it using the following commands:

sudo apt update && sudo apt upgrade -y
sudo apt install python3 python3-pip -y
Install Required Python Packages

Install the requests package using pip:

pip3 install requests

Setup Clone the Repository:

git clone https://github.com/Hafxhak/Near-data-fetcher
cd Near-data-fetcher

Edit the Script: Open the script in a text editor:

nano  near.py

Replace the placeholder URLs in the urls list with your own NEAR RPC endpoint URLs. Example: first main-net then test-net

urls = [
    "https://near.lava.build/lava-referer-your-unique-id/",  # replace with your RPC
    "https://near-testnet.lava.build/lava-referer-your-unique-id/",  # replace with your RPC
]

Save and exit the editor (for nano, press CTRL + X, then Y, and Enter).

Running the Script Install and Use Screen:

Install screen to run the script in a detached session:

sudo apt install screen -y
screen -S near

Run the Script:

Execute the script using Python 3:

python3 near.py

Example Output The script will log the response from the RPC endpoint along with the block height for each request. Example output:

NEAR RPC has been called - Block Height: 12345678
Waiting for 15 seconds before the next call.
Completed cycle of calling all URLs.

Detach from the Screen Session:

Detach from the screen session without stopping the script by pressing CTRL + A, then D.
