Crypto
A crypto price widget is a live cryptocurrency tracker for any embed surface. WidgetCraft's Crypto widget shows real-time prices, 24-hour change, market cap, and volume for any CoinGecko-listed coin — pasteable into Notion dashboards, personal sites, or trading note pages as a single iframe URL.
Crypto is a data-live widget backed by a 60-second-cached CoinGecko proxy on widgetcraft's own backend, so users never need an API key. Three layouts ship: card (one coin, big number + 24h delta + symbol), watchlist (multi-coin list with per-row price + delta), and big (single coin, oversized price for hero modules). Coin selection uses CoinGecko slugs (`bitcoin`, `ethereum`, `solana`, `cardano`, etc.) — the same identifiers CoinGecko uses on their own URLs. Numbers update every 60 seconds and the widget gracefully degrades to a 'loading' state on the first paint.
Questions, answered.
Which coins are supported?
Anything on CoinGecko — currently around 12,000 coins. Use the CoinGecko slug (e.g. `bitcoin` not `BTC`, `ethereum` not `ETH`). The full list lives at coingecko.com.
How do I add a watchlist of multiple coins?
Pick the watchlist layout in the builder and pass comma-separated slugs: `?coins=bitcoin,ethereum,solana,cardano`. The widget renders one row per coin with current price and 24-hour change.
Do I need an API key?
No. WidgetCraft proxies CoinGecko's public API server-side and caches responses for 60 seconds, so widgets render without any user-side credential and CoinGecko's rate limits stay comfortable.
How fresh is the data?
Prices refresh every 60 seconds from the cached proxy. CoinGecko itself updates its public API roughly every minute, so end-to-end latency is 1–2 minutes — typical for free crypto APIs and fine for dashboard use.
Can I show a USD price in another currency?
Currently USD only. Multi-currency support is on the roadmap; for now use the forex widget alongside crypto to show conversion rates.
Is this widget free?
Yes. WidgetCraft widgets are free to embed and customize, with no per-render fees and no signup required.
