- **Price tier:** CoinGlass lists $29-$699/month plans. Tardis.dev lists all-exchange plans from $1,200/month (Solo) with a $300 minimum order; its API serves the first day of each month without a key.
- **Real time:** CoinGlass documents a WebSocket API. Tardis.dev is primarily historical; real-time streaming runs through its client libraries and the Tardis Machine local server.
