# Domains
### History
This endpoint can be used to retrieve the transaction history for all registered domains. Since the response payload will be large, the below optional query parameters can be passed.
`limit` - This is the number of records per response up to 200. 200 is also the default if no limit parameter is passed.
`start_time` - The start in unix timestamp from when the domain transaction records should be obtained.
`end_time` - The end in unix timestamp to when the domain transaction records should be obtained.
`last_token` - This token is used to fetch the next set of responses and is recieved from the API response. After the initial API call, you can pass this as a parameter for further responses.
`order_by` - Sorting direction. Use "ASC" to return results from oldest to newest, or "DESC" (default) to return newest to oldest.

}
```
The `operation` property in the response has the structure below. The `transaction_type` property correlates to `operation` where a value of 0 indicates a registration, and a value of 1 indicates a sale or transfer. For other operations, the `transaction_type` is `null`.
```ts
enum Operation {
Create, // registration (0)
Transfer, // sale or transfer (1)
Update, // update data in a name record (2)
Delete, // delete or burn a domain (3)
Realloc, // change the domain storage size (4)
}
```
