As one of the original validators on SUI we provide full service SUI API access. We support:

* Mainnet
  * JSON-RPC (to be deprecated in 2026)
  * GRPC beta (will be replacing JSON-RP)
  * Walrus storage, publisher and aggregator
  * Seal permissioned server
* Testnet

Sui is rolling out GraphQL alpha, indexed-based APIs, and Triton will support them in Q1-Q2 2026.

Note: the Sui WebSocket API is officially deprecated and is being retired by Mysten Labs.
