# Make batch requests

Multiple requests can be sent at the same time in an array, this is called a [batch](https://www.jsonrpc.org/specification#batch) request, and conforms to the [JSON-RPC 2.0 specification](https://www.jsonrpc.org/specification). Batch is also commonly referred to as "multi-call".

{% hint style="warning" %}
**All requests within the array are counted as individual requests against the daily request limit**.  For example, if the array contains 30 requests, then those 30 requests count against the daily request limit.
{% endhint %}

Each request contained within the array is processed before all the requests are returned. Therefore, when requests are sent in a batch, they will be returned only after every request is processed.

Example batch request (containing 30 requests):

```
curl --request POST \
  --url https://bsc-mainnet.paralinker.com/api/v1/<API-KEY> \
  --header 'Content-Type: application/json' \
  --data '[
