    "blockNumber": 21000000
  },

}

getBlockByNumber

Get blocks by number from multiple chains in a single call. Pass chain:blockNumber pairs. Supports EVM chains, Solana, and Bitcoin in the same batch — Bitcoin returns Bitcoin Core's `getblock` payload (the `confirmations` field drifts as new tip blocks arrive).

curl -X POST https://your-endpoint.simplystaking.xyz/v1 \
  -H "Content-Type: application/json" \

{
  "jsonrpc": "2.0",
  "method": "getBlockByNumber",
  "params": [
    {
      "chain": "ethereum",
      "block": 21000000
    },
    {
      "chain": "bitcoin",
      "block": 900000
    }
  ],
  "id": 1
}

Parameters

Name	Required	Description
items	yes	Comma-separated chain:blockNumber pairs (EVM/Solana/Bitcoin) e.g. ethereum:21000000,bitcoin:900000

Response Fields
