how to get Top pools by total volume locked (TVL), and 24Hr volume by using Uniswap V3 Subgraph
user
Sure, I'd be happy to guide you on how to use Uniswap V3 Subgraph to get top pools by Total Volume Locked (TVL) and 24H volume.

1. First, you'll need to set up your development environment. You can use Node.js, a JavaScript runtime, to interact with the Uniswap V3 Subgraph. You'll also need to have GraphQL API enabled in your setup.

2. Next, you'll need to create a new file for your client, where you import necessary features.

3. Import the `graphql-request` library, which is responsible for sending GraphQL requests to the uniswap V3 Subgraph.

4. Now, you can define a GraphQL query as a string.

   ```javascript
   const query = `
     query {
       poolWithParams(first: 10, orderBy: totalLiquidityUSD) {
         id
         address
         totalLiquidityUSD
         totalLiquidityIon
         totalSupplyUSD
       }
     }
   `;
   ```

   The `poolWithParams` query returns a list of pools sorted by `totalLiquidityUSD`.

5. Finally, you can use `graphql-request` to send it to Uniswap V3 Subgraph.

   ```javascript
   const { Request, response } = require('express');
   const { graphqlRequest } = require('graphql-request');
   const { mergeResponses } = require('@apollo/graphql');

   app.get('/apis/tvl', async (req, res) => {
     const data = await graphqlRequest('https://api.thegraph.com/v4/subgraphs/name/uniswap/v3.0/mainnet', query);

     const result = mergeResponses(data);

     if (result.errors) {
       return res.status(500).send('Internal Server Error');
     }

     if (!result.data) {
       return res.status(400).send('Bad Request');
     }

     res.status(200).json(result.data.poolWithParams);
   });
   ```

   In this code, we send a `GET` request to `https://api.thegraph.com/v4/subgraphs/name/uniswap/v3.0/mainnet`. The `-v3.0` part specifies the version of Subgraph. You'll need to update it to match the Uniswap version you're querying.

   The `data` contains the response from the Subgraph. We merge responses to get the correct response for nested requests.

   If the request failed or data is not present, return appropriate HTTP status code.

6. The same creates an instance of the Express app and handles requests for 24H Volume:

   ```javascript
   const { Request, response } = require('express');
   const { mergeResponses } = require('@apollo/graphql');

   const app = express();

   app.get('/apis/vol', async (req, res) => {
     const data = await graphqlRequest(
       'https://api.thegraph.com/v4/subgraphs/name/uniswap/v3.0/mainnet',
       `
       query {
         poolETH_WETH_ lpToken(first: 1){
           transactions(first: ${req.query.limit ?? 50},orderBy:blockNumber_DESC){
             block
            margin
           }
         }
       }`
     );

     const result = mergeResponses(data);

     if (result.errors) {
       return res.status(500).send('Internal Server Error');
     }

     if (!result.data) {
       return res.status(400).send('Bad Request');
     }

     res.status(200).json({
       volume: 0,
       block: result.data.poolETH_WETH_0.transactions.length
     });
   });

   app.listen(4000, () => {
     console.log('Server up and running!');
   });
   ```

   After handling HTTP requests and sending HTTP responses, the function logs an info message and exits.

7. By doing this, you can send an HTTP request to the endpoint `http://localhost:4000/api/tvl` and `http://localhost:4000/api/vol` with your respectively requested parameters.

It's always recommended to review the Uniswap V3 Subgraph API to ensure you are using the correct method calls and parameters. These instructions are not exhaustive, so study the API, and, in truth, reduce the demands to your necessities.

how to get Top pools by total volume locked (TVL), and 24Hr volume by using Uniswap V3 Subgraph
user
To get the top pools by total volume locked (TVL) and 24-hour volume using the Uniswap V3 Subgraph, you'll need to use GraphQL queries. Here's a step-by-step guide:

1. **Access the Uniswap V3 Subgraph**: The Uniswap V3 Subgraph is hosted on The Graph network. You can access it via the following URL: `https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v3`

2. **Write a GraphQL Query**: GraphQL is a query language for APIs. Here's an example of a query that fetches the top 5 pools sorted by TVL:

```graphql
{
  pools(first: 5, orderBy: totalValueLockedUSD, orderDirection: desc) {
    id
    totalValueLockedUSD
    volumeUSD
  }
}
```

In this query, `first: 5` specifies that we want the top 5 pools, `orderBy: totalValueLockedUSD` sorts the pools by TVL, and `orderDirection: desc` sorts them in descending order. The `id`, `totalValueLockedUSD`, and `volumeUSD` fields are the data we want to fetch for each pool.

Please note that the `volumeUSD` field represents the total volume, not the 24-hour volume. The Uniswap V3 Subgraph does not directly provide 24-hour volume data. You would need to calculate this yourself by fetching volume data for the past 24 hours and subtracting the volume from 24 hours ago from the current volume.

3. **Send the Query**: You can send the query to the Uniswap V3 Subgraph by making a POST request to the subgraph's URL with the query in the request body. You can do this using a tool like `curl` or `fetch`, or by using a GraphQL client like Apollo Client.

Here's an example using `fetch` in JavaScript:

```javascript
fetch('https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v3', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ query: '{ pools(first: 5, orderBy: totalValueLockedUSD, orderDirection: desc) { id, totalValueLockedUSD, volumeUSD } }' }),
})
.then(response => response.json())
.then(data => console.log(data));
```

This will print the query response to the console.

Remember to replace `'your-query-here'` with your actual GraphQL query.

Please note that you'll need to handle pagination if there are more than 5 pools. The GraphQL API only returns a limited number of results per query, so you'll need to make multiple queries to fetch all the data.

Also, keep in mind that the Uniswap V3 Subgraph is a third-party service that's not operated by Uniswap. It may have limitations or restrictions on usage, and it may not always be available or up-to-date. Always make sure to handle errors and retries in your code.

For more information about the Uniswap V3 Subgraph, you can refer to the [Uniswap V3 Subgraph documentation](https://github.com/Uniswap/v3-subgraph). For more information about GraphQL, you can refer to the [GraphQL documentation](https://graphql.org/learn/).
