API

The API module classes provide client classes for interacting with the Helium APIs.

For full API specification and documentation please reference docs.helium.com.

from datetime import datetime, timedelta
from helium_py.api import ChainVariables, Hotspots

# Example of fetching chain variables
chain_vars = ChainVariables()  # Create a ChainVariables client
print(chain_vars.get_all())    # Get all chain variables

# Example of fetching hotspot earnings for the last five days
hotspot_address = "some_valid_hotspot_address"
hotspots = Hotspots()
hotspots.get_hotspot_rewards_total(hotspot_address, min_time=datetime.now() - timedelta(days=5))

Crypto

The Crypto module classes provide Address, Keypair, and Mnemonic classes as well as helpful utilities.

from helium_py.crypto.keypair import Keypair

# Example of creating a random keypair, accessing the address, and signing a message
keypair = Keypair.make_random()
address = keypair.address.b58  # B58 public key address
keypair.sign(b'message')  # Sign a message with keypair private key
