Live data from the public Steam Market — highest‑value items, price history, and market status.
EN — Soulstone never touches the game: no memory reading, no code injection, no input automation. It works exclusively with public Steam Community Market data (HTTP, no login). That's what separates it from bots (which get you banned) and from malware bait — and what makes it defensible as a portfolio piece.
PT — Soulstone nunca toca no jogo: nada de ler memória, injetar código ou automatizar input. Trabalha exclusivamente com dados públicos do Steam Community Market (HTTP, sem login). É isso que o separa de bots (que dão ban) e de iscas de malware.
TBH: Task Bar Hero is a free‑to‑play idle RPG that went viral on Steam (~415k peak concurrent players) thanks to a real‑money economy: you farm loot AFK and sell it on the Steam Market for Steam balance. The game never tells you where it's worth farming or how the market moves. Soulstone fills that gap with live data — without ever touching the game process (zero ban risk).
Steam has no inbound webhooks, and its full price history requires a login. So Soulstone builds the history itself by snapshotting the public search/render endpoint on a schedule. That time series is the product.
- ⏱️ Poller (Supabase Edge Function) — paginates the Steam Market, respects rate limits (delay + 429 backoff), with an isolated, unit‑tested parser.
- 🗄️ Postgres time series — every poll is a timestamped snapshot; RLS keeps it public‑read.
- 📊 Single‑page dashboard — highest‑value items, a price × time chart, and live market status. Rarity‑colored, dark, fast.

O TBH: Task Bar Hero é um idle RPG free‑to‑play que viralizou na Steam (~415 mil jogadores simultâneos de pico) por causa de uma economia de dinheiro real: você farma loot AFK e vende no Steam Market por saldo Steam. O jogo não explica onde vale a pena farmar nem como o mercado se move. Soulstone preenche essa lacuna com dados ao vivo — sem nunca tocar no processo do jogo (zero risco de ban).
A Steam não tem webhooks de entrada, e o histórico completo exige login. Então o Soulstone constrói o histórico sozinho, snapshotando o endpoint público search/render de tempos em tempos. Essa série temporal é o produto.
- ⏱️ Poller (Supabase Edge Function) — pagina o Steam Market, respeita rate limit (delay + backoff em 429), com um parser isolado e testado.
- 🗄️ Série temporal no Postgres — cada coleta é um snapshot com timestamp; RLS mantém leitura pública.
- 📊 Dashboard de página única — itens de maior valor, gráfico de preço × tempo e status do mercado ao vivo. Dark, rápido, com cores de raridade.
