The `pairlist_url` option specifies the URL of the remote server where the pairlist is located, or the path to a local file (if file:/// is prepended). This allows the user to use either a remote server or a local file as the source for the pairlist.
The `save_to_file` option, when provided with a valid filename, saves the processed pairlist to that file in JSON format. This option is optional, and by default, the pairlist is not saved.

??? Note
Example:
`save_to_file` can be used to save the pairlist to a file with Bot1:
```json
"pairlists": [
{
"method": "RemotePairList",
"mode": "whitelist",
"pairlist_url": "https://example.com/pairlist",
"number_assets": 10,
"refresh_period": 1800,
"keep_pairlist_on_failure": true,
"read_timeout": 60,
"save_to_file": "user_data/filename.json"
}
]
```
This saved pairlist file can be loaded by Bot2, or any additional bot with this configuration:
```json
"pairlists": [
{
"method": "RemotePairList",
"mode": "whitelist",
"pairlist_url": "file:///user_data/filename.json",
"number_assets": 10,
"refresh_period": 10,
"keep_pairlist_on_failure": true,
}
]
```
The user is responsible for providing a server or local file that returns a JSON object with the following structure:
