Example: fetch and parse a USDT Transfer Event

import os
import web3
import web3research
from web3research.evm import SingleEventDecoder
from web3research.common import Address

# for internet
w3r = web3research.Web3Research(api_token=YOUT_APIKEY)

USDT_address = Address('0xdac17f958d2ee523a2206206994597c13d831ec7')

log = w3r.eth.events(
    where=f"address = {USDT_address}", 
    order_by={"blockNumber", True},
    limit=1
)[0]

w3 = web3.Web3()

abi = {
    "anonymous": False,
    "inputs": [
        {"indexed": True, "name": "from", "type": "address"},
        {"indexed": True, "name": "to", "type": "address"},
        {"indexed": False, "name": "value", "type": "uint256"},
    ],
    "name": "Transfer",
    "type": "event",

decoder = SingleEventDecoder(w3, event_abi=abi)
result = decoder.decode(log)
print(result)
