6Find the token ID of the Uniswap position you wish to get details about. If you own the liquidity position, you can head to https://app.uniswap.org/pool and click on the v3 position. The ID of that position will be in the URL of the details page.
7
8Append the token ID to the end of this val's URL to fetch data about it (e.g. to get information about token ID `12345`, fetch the url `https://midnightlightning-uniswapv3position.web.val.run/12345`)
9
10# Reference
11This val fetches blockchain data from the following smart contracts:
12
13- **NonfungiblePositionManager(`0xc36442b4a4522e871399cd717abdd847ab11fe88`)** Manages the liquidity position tokens as an ERC721 contract. The `positions` function is used to determine what tokens and tick ranges the individual liquidity position has.
14- **UniswapV3Factory (`0x1F98431c8aD98523631AE4a59f267346ea31F984`)** Contract that manages liquidity pools, and acts as a registry to record where each pairing is deployed to. The `getPool` function is used to find where the smart contract for a specific pairing of ERC20 tokens is deployed to.
15- **ERC20 tokens** Each position has two tokens it's balancing between, and each token has its own instance of an ERC20 contract deployed to the blockchain. The `name` and `symbol` functions are used to determine how to describe each token, and the `decimals` function to determine how to scale the price value for the ratio between them.
16- **UniswapV3Pool** Contract that handles swaps between specific pairs of tokens. The `slot0` function is used to fetch the current price the two tokens are swapping at.
