slotsUpdatesSubscribe

Subscribe to detailed slot lifecycle updates on the Solana route (Beta).

Available under Solana WebSocket API (Beta). Use the chain-family pages for handle discovery and this page for exact subscription semantics.

Stage: Beta

Access

Surfaces: raw_rpc_ws
Metering: raw_rpc_ws_target_minute
Scope: Solana slot updates subscription

Handles

Surface	Label	Value
`raw_rpc_ws`	Endpoint	`wss://gw-aql.tomo.services/rpc/solana/wss`
`raw_rpc_ws`	Auth header	`Bearer <api_key>`
`raw_rpc_ws`	Subscribe method	`slotsUpdatesSubscribe`
`raw_rpc_ws`	Notification method	`slotsUpdatesNotification`

Use `slotsUpdatesSubscribe` when the runtime needs richer slot lifecycle events than the compact `slotSubscribe` payload.

This beta example uses `/rpc/solana/wss` and the reviewed `slotsUpdatesSubscribe` request shape.
