slot-info

The GetSlotInfo endpoint can be used to determine whether the leader of a slot is malicious or non-malicious. Data is supported for the past two historic epochs, the current one, and the future one.

Use this endpoint’s data with caution. The maliciousness determination relies on historical block-building behavior during the leader’s previous slots. The data may be unreliable for newly staked validators without historical activity or if the validator is engaging in new, previously unseen MEV behaviours.

Note: This endpoint is available exclusively to Ultra-tier customers.
