    ],
    "rows": 5
  }
]

Note: The result collection above is limited to its first 10 items for documentation purposes; this example returned 5 rows because limit=5 was requested.

This demonstrates pagination: with offset=10, the response starts at hour 12:00:00 UTC, i.e. the hour immediately preceding the last row returned in Example 1. This confirms continuous, non-overlapping hourly coverage.

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://x402.cambrian.org/evm/price-hour"
);
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://x402.cambrian.org/evm/price-hour")
        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 through 5 automatically.
