Performance samples are taken every 60 seconds and include the number of transactions and slots that occur in a given time window.. ## OpenAPI ````yaml openapi/rpc-http/getRecentPerformanceSamples.yaml POST / openapi: 3.1.0 info: title: Solana RPC API version: 1.0.0 description: >- Network performance analytics API for monitoring Solana blockchain throughput, transaction processing rates, and real-time health metrics across recent time periods. license: name: Apache 2.0 url: https://www.apache.org/licenses/LICENSE-2.0.html servers: - url: https://mainnet.helius-rpc.com description: Mainnet RPC endpoint - url: https://devnet.helius-rpc.com description: Devnet RPC endpoint security: [] paths: /: post: tags: - RPC summary: getRecentPerformanceSamples description: > Retrieve detailed performance metrics about the Solana blockchain's recent operational efficiency. This network analytics API provides time-series data showing transaction throughput, slot production, and voting activity across regular sampling intervals. Essential for monitoring network health, analyzing blockchain capacity, tracking performance trends, and verifying network reliability. The metrics offer insights into both the overall transaction volume and specifically non-voting transactions, helping differentiate between consensus overhead and actual user operations on the network. operationId: getRecentPerformanceSamples requestBody: required: true content: application/json: schema: type: object required: - jsonrpc - id - method properties: jsonrpc: type: string description: The JSON-RPC protocol version. enum: - '2.0' example: '2.0' default: '2.0' id: type: string description: A unique identifier for the request. example: '1' default: '1' method: type: string description: The name of the RPC method to invoke. enum: - getRecentPerformanceSamples example: getRecentPerformanceSamples default: getRecentPerformanceSamples params: type: array description: Optional parameter to limit the number of samples to return. default: - 4 items: type: integer description: >- Number of historical performance sample intervals to retrieve (maximum 720, representing up to 12 hours). example: 4 responses: '200': description: Successfully retrieved performance samples. content: application/json: schema: type: object properties: jsonrpc: type: string description: The JSON-RPC protocol version. enum: - '2.0' example: '2.0' id: type: string description: Identifier matching the request. example: '1' result: type: array description: List of performance samples. items: type: object description: Performance sample data. properties: slot: type: integer description: >- Solana blockchain slot at the end of this performance sampling period. example: 348125 numTransactions: type: integer description: >- Total number of transactions processed during this sampling window, including both user transactions and validator votes. example: 126 numNonVoteTransactions: type: integer description: >- Number of actual user transactions (excluding validator consensus votes) processed in this period. example: 1 samplePeriodSecs: type: integer format: int16 description: >- Duration of this performance measurement window in seconds, typically 60-second intervals. example: 60 numSlots: type: integer description: >- Number of Solana slots successfully produced during this sampling period, indicating blockchain progress. example: 126 '400': description: Bad Request - Invalid request parameters or malformed request. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32602 message: Invalid params id: '1' '401': description: Unauthorized - Invalid or missing API key. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32001 message: Unauthorized id: '1' '429': description: Too Many Requests - Rate limit exceeded. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32005 message: Too many requests id: '1' '500': description: Internal Server Error - An error occurred on the server. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32603 message: Internal error id: '1' '503': description: Service Unavailable - The service is temporarily unavailable. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32002 message: Service unavailable id: '1' '504': description: Gateway Timeout - The request timed out. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: jsonrpc: '2.0' error: code: -32003 message: Gateway timeout id: '1' security: - ApiKeyQuery: [] components: schemas: ErrorResponse: type: object properties: jsonrpc: type: string description: The JSON-RPC protocol version. enum: - '2.0' example: '2.0' error: type: object properties: code: type: integer description: The error code. example: -32602 message: type: string description: The error message. data: type: object description: Additional data about the error. id: type: string description: Identifier matching the request. example: '1' securitySchemes: ApiKeyQuery: type: apiKey in: query name: api-key description: >- Your Helius API key.
