# Query Collection

{% hint style="warning" %} <mark style="color:red;">**Collections is an analytics API (not real-time, though it may look like one).**</mark>

<mark style="color:red;">**Not all filters and sortings are working now. Data is provided only for the past 7 days.**</mark>
{% endhint %}

## When you may need collections?

If you want to apply some custom filters and sortings on the data.

## About collections

There are a few collections with blockchain data:

* *accounts*: blockchain account data;
* *transactions*: transactions related to accounts;
* *messages*: input and output messages related to transactions;
* *blocks*: blockchain blocks.
* *block\_signatures* : validator block signatures

[Use `query_collection` method to query data that can be filtered and sorted](https://docs.everos.dev/ever-sdk/reference/types-and-methods/mod_net#query_collection).

## Usage

```javascript
await client.net.query_collection({
    collection: 'accounts',
    filter: {
        id: {
            eq: wallet1Address
        }
    },
    result: 'balance'
})
```
