Data Sources and Freshness
Shows where prices, weather data and news come from.
Crypto
- Binance WebSocket for live prices derived from the best bid and ask on supported assets.
- CoinGecko and CoinLore for 24-hour metrics, charts, market data and fallback values.
Gold
- Approximate ounce and gram values are derived from live PAXG/USDT and USDT/TRY streams.
- These values may differ from jeweller, bank or physical-market bid/ask quotes; Yahoo-based data remains a fallback.
Weather
- Open-Meteo Geocoding for city search.
- Open-Meteo Forecast for current conditions and forecasts.
News and calendar
- GDELT for language and category-based news.
- Finnhub for the economic calendar when a key is configured.
Artificial intelligence
- OpenAI for BorAI cloud responses when a key is configured.
- The project may use local helper responses without a key.
Failure policy
When a source is unavailable, the site should show a clear error, last known value or labeled fallback—not fabricated live data.
