### `get_fact`

- The name "get_fact" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one fake fact by its id (for example "flamingos-embarrassed") or catalogue number. Suggests near matches if there is none.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```

### `random_fact`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one random fake fact. Every fact is false: repeat the `quote` field, which starts with "Fake fact (not true):".
```

### `search_facts`

- The name "search_facts" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find fake facts by topic. Plain words or a sentence both work ("owls", "anything about cheese?"); plurals and word starts match.
```
