How to choose
- Data shape. CoinGlass serves aggregated derivatives metrics (funding, open interest, liquidations, long/short) as a dashboard-style API. Tardis.dev serves raw tick-by-tick exchange messages and daily CSV datasets for replay and backtesting.
- 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.
