Just the data.
Use it on its own, without integrating the rest of ParlayX.
- Data keysRead-only keys for market discovery and the orderbook stream, with no access to orders or balances.
- Nothing to custodyNo wallets, no venue accounts and no funding. The Data plan never touches capital.
Questions, answered.
Do I need to use the rest of ParlayX?
