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/token-mint-burn-transactions"
);
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/token-mint-burn-transactions")
        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.
