Switch X display language

Change the display language for the signed-in X (Twitter) account, under Settings > Accessibility, display, and languages > Languages. Takes an X locale code (e.g. fr, de, en, it, es, en-gb, zh-cn) and applies it immediately — the account's interface language changes account-wide until switched again. This only affects X's own UI text (menus, buttons), not the language of tweets in your timeline.

Input

locale required

X locale code to switch the account's display language to, e.g. "fr", "de", "en", "it", "es" (also accepts region/script variants X exposes, like "en-gb", "zh-cn", "ar-x-fm").

Output

label required

The language's display name as shown in the selector, e.g. "French - français".

locale required
was_already required

True if the account's display language already matched the requested locale before this call.

verified_on_page required

True if the page was re-inspected after the change and the display language is now confirmed set to the requested locale.

Search X tweets

Search X for tweets, supporting all X search operators; the tab arg picks 'top' (ranked sample, default) or 'latest' (chronological). Returns per tweet a canonical record: id, url, author {id, handle, name}, text, created_at, lang, likes, retweets, replies, quotes, bookmarks, views, is_retweet, is_quote, plus followers (the author's follower count, a search-only enrichment), and the top-level query and count. Top is a ranked sample, not exhaustive.

Get X user posts

Get a user's Posts tab by handle (x.com/<handle>) — their own tweets and self-threads, newest first. Excludes replies to others (see get_user_replies for the Replies tab), and excludes reposts, which X keeps on a separate Reposts tab. The post count shown on the profile header includes replies, so expect fewer items than that number. Returns per tweet: id, url, text, created_at, lang, likes, retweets, replies, quotes, views, bookmarks, is_retweet, is_quote. Count is capped by how far X paginates before throttling.
