Wow, thanks. Hm, yeah, porting from Typescript to Python seems overwhelming( Means we are a little stuck. We tried to get quotes from 1inch via Node. But 1inch removed this function in new protocol, now its possible to get quotes only via API, and API has a really low limits :( |

Well, you could try to use mentioned package locally to get quotes. I'm not an expert, but it seems not that difficult for me to create such interaction via some REST API. |

Hi. Firstly, thanks a lot for you work, its great. We managed to track price from Uniswap v2. But with Uni v3 we have a huge issue:
Function get_price_output returns price only from one direct pool. For example, if there are 2 pools WETH/token and USDC/token, function will quote only from one of them. That means that function will return the price not as efficient, as if i buy on Uniswap V3 manually. Function is not using router, i guess.
So, my question is expected: how can i get a price from uniswap v3 with optimal routing? The code below:
address = None # or None if you're not going to make transactions
private_key = None # or None if you're not going to make transactions
version = 3 # specify which version of Uniswap to use
provider = “infura” # can also be set through the environment variable
PROVIDERuniswap = Uniswap(address=address, private_key=private_key, version=version, provider=provider)
total = {}
usdc = "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"
coin_to_check = "0x2b591e99afE9f32eAA6214f7B7629768c40Eeb39"
qty = uniswap.get_price_output(usdc,coin_to_check, 1000 * 10 ** 8,fee=3000)
print(qty)
