Latest Block Number and Time

This endpoint returns the latest block number and block time for the Solana blockchain. It provides real-time information about the most recently processed block, including the block number, Unix timestamp, and UTC timestamp.

Business Value

• Real-time Monitoring: Track the current state of the Solana blockchain with up-to-date block information
• Synchronization: Ensure applications are synchronized with the latest blockchain state
• Latency Measurement: Calculate blockchain processing delays by comparing block times with current time
• Health Checks: Monitor blockchain network health and block production rates
• Data Pipeline: Use as a reference point for blockchain data processing and ETL operations

Examples

1. Get Latest Block Information

This example demonstrates how to retrieve the current latest block information from Solana.

curl -X GET "https://opabinia.cambrian.network/api/v1/solana/latest-block" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json"

Response:

{
  "columns": [
    {
      "name": "blockNumber",
      "type": "UInt64"
    },
    {
      "name": "blockUnixTime",
      "type": "UInt32"
    },
    {
      "name": "blockUTCTime",
      "type": "String"
    }
  ],
  "data": [
    [
      392362393,
      1767967687,
      "2026-01-09T14:08:07Z"
    ]
  ],
  "rows": 1
}

The response shows the latest block number 392362393, which was processed at Unix timestamp 1767967687 (2026-01-09T14:08:07Z).

2. Monitor Blockchain Health

This example shows how to use the latest block endpoint for blockchain health monitoring.

curl -X GET "https://opabinia.cambrian.network/api/v1/solana/latest-block" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json"

Response:

{
  "columns": [
    {
      "name": "blockNumber",
      "type": "UInt64"
    },
    {
      "name": "blockUnixTime",
      "type": "UInt32"
    },
    {
      "name": "blockUTCTime",
      "type": "String"
    }
  ],
  "data": [
    [
      392362393,
      1767967687,
      "2026-01-09T14:08:07Z"
    ]
  ],
  "rows": 1
}

You can compare the block timestamp with the current time to measure blockchain processing latency and ensure the network is functioning properly.

x402 Payment Option

This endpoint supports pay-per-use access via the x402 payment protocol (v2) — pay $0.05 USDC per request using blockchain micropayments. No API key required.

Quick Start (TypeScript)

npm install @x402/fetch @x402/evm viem

import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { wrapFetchWithPayment } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(process.env.EVM_PRIVATE_KEY as `0x${string}`);
const client = new x402Client();
client.register("eip155:*", new ExactEvmScheme(signer));

const fetchWithPayment = wrapFetchWithPayment(fetch, client);
const response = await fetchWithPayment(
  "https://deep42.cambrian.network/api/v1/solana/latest-block"
);
const data = await response.json();

Quick Start (Python)

pip install "x402[httpx]"

import asyncio, os
from eth_account import Account
from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.evm import EthAccountSigner
from x402.mechanisms.evm.exact.register import register_exact_evm_client

async def main():
    client = x402Client()
    account = Account.from_key(os.getenv("EVM_PRIVATE_KEY"))
    register_exact_evm_client(client, EthAccountSigner(account))

    async with x402HttpxClient(client) as http:
        response = await http.get("https://deep42.cambrian.network/api/v1/solana/latest-block")
        print(response.json())

asyncio.run(main())

Payment Flow

1. Send a normal request to the endpoint (no API key needed)
2. Server returns 402 Payment Required with payment details
3. The x402 SDK automatically signs a payment authorization with your wallet
4. The SDK resubmits the request with the signed payment
5. Server verifies payment and returns the API response

The x402 SDK handles steps 2–5 automatically.

Network: Base (chain ID 8453) | Currency: USDC | Price: $0.05 per request
