Probably

Web demo showing live BTC, ETH and XRP prices with a shared Jev buy-or-wait judgment per coin; no trades placed.

Overview

Probably is a web demo that shows live BTC, ETH and XRP prices alongside a shared TypeSafe buy-or-wait judgment. Every 15 seconds prices refresh, and each coin's last 60 seconds of actual Coinbase trades are aggregated into up to twelve five-second OHLC and volume samples; the AI considers a hypothetical entry for the next 60 seconds and does not predict returns. If the trade window is incomplete or stale, the app withholds that coin's signal rather than fabricating data.

One inference request covers all coins at most once per 60 seconds per warm server instance. A JSON toggle shows the exact samples, timestamps, confidence and token count without new requests. It caches in server memory by default and can coordinate across Vercel instances through Upstash Redis with a refresh lease and atomic inference cooldown, failing closed if configured Redis is unavailable. API keys stay server-side. It places no trades and is not financial advice.

How it works

  1. Fetch recent Coinbase trades and aggregate samples.
  2. Send all coins in one Jev request at most once a minute.
  3. Show buy/wait and confidence per coin.
  4. Withhold signals when data is insufficient.

Strengths

  • No fabricated samples.
  • Cost-controlled shared inference.
  • Transparent JSON view.

Caveats

  • Demonstration only; no trades.
  • Very short horizon judgments are noisy.

Getting started
