Rumble has some documentation suggesting the existence of an official API, but it appears all requests for API keys have fallen on deaf mailboxes. This is working, for now:

#!/usr/bin/env bash
#rts/oarion7

# Search for videos on rumble.com, returns url(s) for selected results; tab key to select multiple

# Dependencies: xmllint, rlwrap, jq, fzf https://github.com/junegunn/fzf
# Needs a recent enough fzf to support {n} placeholders and the become() event

# Recommended: https://github.com/yt-dlp/yt-dlp/

history_file="$HOME/.config/rumble_search_history"
UA=$(<"$HOME/scripts/UserAgent/string.txt") #Spoof an updated UA string just in case.

if [[ -z "$@" ]] ; then
    printf '\n%s\n' '=>> Search for Rumble videos'
    #read -p "> " readitem
    readitem=$(rlwrap -S '> ' -H "$history_file" -o cat) 
else
    readitem="$@"
fi

query="$( printf '%s\n' "$readitem" | tr -d '\n' | tr -d '!' | tr -d "'" | jq -sRr @uri )"

[[ -z "$query" ]] && exit

html=$(curl -A "$UA" -Ss "https://rumble.com/search/all?q=$query")

[[ -z "$html" ]] && { printf '%s\n' "Error fetching results." ; exit 1; } 

list=$(for i in $(seq "$(printf '%s\n' "$html" | xmllint --html --xpath 'count((//li/article//a/div/img))' - 2>/dev/null)") 
    
    do

        title="$(printf '%s\n' "$html" | xmllint --html --xpath "string((//img[@class='video-item--img']) [$i]/@alt)" - 2>/dev/null )"
        url="$(printf '%s\n' "$html" | xmllint --html --xpath "string((//a[@class='video-item--a']) [$i]/@href)" - 2>/dev/null )"
        time="$(printf '%s\n' "$html" | xmllint --html --xpath "string((//time[@class='video-item--meta video-item--time']) [$i]/@datetime)" - 2>/dev/null )"

        printf '%s:\t %s\n' "$(printf '%s\n' "$time" | cut -c-10)" "$title" | tr -cd '.,?!`!@#$%^&*()"-=_+[]{}|:;<>a-zA-Z0-9 \n'

    done)

[[ -z "$list" ]] && { printf '%s\n' "No results found." ; exit 1; } 

_conv() { printf '%s\n' $(( "$1" + 1 )) ; }

for i in $( printf '%s\n' "$list" |  fzf -m --bind 'enter:become(printf "%s\\n" {+n})') ; do 
    url_part="$(printf '%s\n' "$html" | \
        xmllint --html --xpath "string((//a[@class='video-item--a']) ["$(_conv "$i")"]/@href)" - 2>/dev/null )"
    printf 'https://rumble.com%s\n' "$url_part"
done
