Legacy API scheduled for removal
Sui Foundation disabled JSON-RPC on Mainnet full nodes the week of July 27, 2026, and plans full decommission, including code removal, for mid-October 2026, when this reference moves to the archive. Use this page to identify the legacy methods your application still calls, not to build new integrations. Call gRPC or GraphQL RPC instead, and see the JSON-RPC Migration Guide for the method-by-method mapping.
Complete reference for the legacy Sui JSON-RPC API. Browse methods, request parameters, and response schemas to identify the calls your application still depends on, then map each one to its gRPC or GraphQL replacement.
