# getHighestSnapshotSlot ## getHighestSnapshotSlot — Highest slots covered by snapshots > Returns the highest slot information that the node has snapshots for. This will find the highest full snapshot slot, and the highest incremental snapshot slot based on the full snapshot slot, if there is one. Version Restriction : This method is only available in solana-core v1.9 or newer. Please use getSnapshotSlot for solana-core v1.8 and below. ```json {"openapi":"3.0.3","info":{"title":"Solana RPC: getHighestSnapshotSlot","version":"1.0.0"},"tags":[{"name":"Block","description":"Solana RPC block method."}],"servers":[{"url":"https://public.rpc.solanavibestation.com","description":"Public endpoint (rate-limited, no auth)"},{"url":"https://lite.rpc.solanavibestation.com","description":"Lite tier"},{"url":"https://basic.rpc.solanavibestation.com","description":"Basic tier"},{"url":"https://ultra.rpc.solanavibestation.com","description":"Ultra tier"},{"url":"https://elite.rpc.solanavibestation.com","description":"Elite tier"},{"url":"https://epic.rpc.solanavibestation.com","description":"Epic tier"},{"url":"https://basic.swqos.solanavibestation.com","description":"Basic tier with Stake-Weighted QoS"},{"url":"https://ultra.swqos.solanavibestation.com","description":"Ultra tier with Stake-Weighted QoS"},{"url":"https://elite.swqos.solanavibestation.com","description":"Elite tier with Stake-Weighted QoS"}],"security":[{},{"AuthHeader":[]},{"URLParameter":[]}],"components":{"securitySchemes":{"AuthHeader":{"type":"apiKey","in":"header","name":"Authorization","description":"Pass `Authorization: ` on each request."},"URLParameter":{"type":"apiKey","in":"query","name":"api_key","description":"Pass `?api_key=` on the URL."}},"schemas":{"JsonRpcEnvelope":{"type":"object","required":["jsonrpc","id"],"description":"Base envelope of every JSON-RPC 2.0 response.","properties":{"jsonrpc":{"type":"string","enum":["2.0"]},"id":{"oneOf":[{"type":"string"},{"type":"integer"}],"description":"Echoed request id."}}},"JsonRpcErrorResponse":{"type":"object","required":["jsonrpc","id","error"],"description":"JSON-RPC 2.0 error response.","properties":{"jsonrpc":{"type":"string","enum":["2.0"]},"id":{"oneOf":[{"type":"string"},{"type":"integer"}]},"error":{"$ref":"#/components/schemas/JsonRpcError"}}},"JsonRpcError":{"type":"object","required":["code","message"],"description":"Structured JSON-RPC error.","properties":{"code":{"type":"integer","description":"Numeric error code per JSON-RPC 2.0 spec.
