habbo mp
tracker.

a telegram bot for habbo.com's player marketplace. type a furni name, get prices in seconds: ranked search, 30-day trend charts, inline lookups from any chat, and alerts that ping you when something drops below your price.

live on telegram, read commands open to everyone (rate limited). watches stay whitelisted so strangers can't farm my cron.

[ how / it works ] three steps, no spreadsheet
01
search

type part of a name and a ranked search (exact, then prefix, then substring) picks the right furni out of fifteen thousand. up to ten results, priced in a single batched api call, never one request per item.

02
chart

/history draws a 30-day price chart as a png. cloudflare workers can't draw, so the bot builds a chart.js config and quickchart renders it. watched items get a second, intraday chart from the bot's own 30-minute snapshots.

03
watch

set a price threshold and a cron checks every 30 minutes. alerts fire once per crossing, then re-arm when the price recovers, so a cheap week doesn't mean forty identical pings.
