6### Val Town-Hosted SQLite
7
8[Val Town](https://val.town/) hosts SQLite as part of its standard library ([@std/sqlite](https://val.town/v/std/sqlite)). This makes a fetch request against their closed-source API (using your API token) which returns results in a consistent format. This is great because you can host your own endpoints that work similarly, and _reuse code that was only designed in mind for that original hosted interface_
9
10The standard format (abridged to important fields):
143#### Default `options.interfaces.patterns`:
144
145- `patterns.https` - `/^https:\/\//` ( `https://example.com/somePath/tableName`): fetch from `https://example.com/somePath/batch`
146- `patterns.val` - `/^@/` (`@author/name/somePath/tableName`): fetch from the val's endpoint, `https://author-name.web.val.run/somePath/batch`
147
148#### Other Available Patterns:
13## Examples
14
15### Fetching the val code
16
17```console
21You can also use `js`, `jsx` and `ts` extension (only the content-type change, there is no transpilation).
22
23### Fetching private val
24
25Pass an api token as an username
29```
30
31### Fetching the val README
32
33```console
41```
42
43### Fetching a specific version of a val
44
45```console
49You need to be authenticated to use this method.
50
51### Fetching the val metadata
52
53```console
