Leader schedule
Leader schedule names the validator leading each slot, in order, starting from the slot you request.
Solana Leader Slot API: schedule, stake, location & ping
Leader Slot API
Know who's leading the next slot.
The leader rotates slot by slot, and the order is redrawn every epoch.
That makes it something you check as you go, not a fact you note once and set aside.

In every response
Get schedule, stake, location, and ping in one call.
Each record names the leader for that slot, their stake weight, and their estimated city, country, and network operator. A Solana epoch runs about 432,000 slots; keeping the leader schedule, each leader's location, and reference ping current across all of them takes a dedicated pipeline. We maintain it, so you read the map instead of building one.
Stake weight
Stake weight is drawn from the current epoch: validators with more stake tend to appear in the leader schedule more often over time.
Leader location
Leader location comes from the validator's estimated city, country, coordinates, and network operator, so you can place each leader before you connect.
Reference ping
Reference ping comes from ERPC's seven observation regions (Frankfurt, Amsterdam, New York, London, Tokyo, Singapore, Sydney), each measured independently, so a slower or missing reading from one region does not mean a leader is unreachable.
