# Get Bonding Curve Details by Pool Address

Each Launchpad pool uses a <mark style="color:yellow;">bonding curve</mark> to manage price and token distribution. By querying the pool using its address, we can fetch detailed curve parameters like virtual reserves, tokens sold, and total funds raised. Shyft's GraphQL API enables us to query and filter pool data based on any available field. Here, we filter by the `pubkey` field to fetch the bonding curve details for the corresponding pool.

You can directly copy paste this code on <mark style="color:yellow;">replit</mark> and see it in action.

                pubkey
            }
        }`; //you can cherrypick the fields as per your requirement

  const result = await fetch(

    {
      method: "POST",
      body: JSON.stringify({
        query: operationsDoc,
        variables: {},
        operationName: "MyQuery",
      }),
    }
  );

  const { errors, data } = await result.json();

  if (errors) {
    console.error(errors);
    console.log(
      "Failed to fetch data, please provide correct API key or pool address."
    );
    return;
  }

  console.dir(data, { depth: null });
}

getBondingCurveByPoolAddress("4yhL99wpeeM2ptRT6U81hG8P3bCaCNabuw28gSBTCemU");
```

{% endcode %}
{% endtab %}

{% tab title="Response" %}

```json
{
  "raydium_launchpad_PoolState": [
    {
      "supply": 100000000000000,
      "total_base_sell": 80000000000000,
      "total_quote_fund_raising": 85000000000,
      "virtual_base": 106666666666666,
      "virtual_quote": 28333333333,
      "real_base": 408443396730,

      "pubkey": "4yhL99wpeeM2ptRT6U81hG8P3bCaCNabuw28gSBTCemU"
    }
  ]
}
```

{% endtab %}
{% endtabs %}

The response contains the following fields which involves the fields of the bonding curve

* `supply`: Total base token supply in the bonding curve.
* `total_base_sell`: Total base tokens sold so far via the curve.
* `total_quote_fund_raising`: Total SOL (quote tokens) raised from buyers.
* `virtual_base` & `virtual_quote`: Curve parameters that define price behavior depending on the curve type (e.g., for Constant Product or Fixed Price).
* `real_base` & `real_quote`: Actual on-chain token balances in the pool vaults (useful for pricing and tracking liquidity backing).
* `curveType` (Available on Global Config): A curvetype `0` indicates a constant curve, `1` means constant price, and `2` means linear. This data is essential for token price calculation.

However, these are not the only fields available in the <mark style="color:yellow;">PoolState</mark> account, other fields such as `quote_mint`, `base_mint` can also be cherrypicked, or omitted as per your requirement.&#x20;

In the next example we will explore how we can fetch more Pool details on Raydium Launchpad, which is as simple as adding more fields on the request query.
