Cambrian Token Price (Current) API

By Cambrian Network base

GET /api/v1/evm/price-current

Token Price (Current)

Overview

Returns the current USD price of an EVM token calculated based on Uniswap V3 and compatible liquidity pools. The price is derived from on-chain liquidity pool data, providing accurate real-time pricing for any whitelisted EVM token. Results include the chain ID, token address, symbol, price in USD, and the timestamp of the last update.

Business Value

  • Real-Time Token Pricing: Instantly retrieve the latest USD price for any supported EVM token without needing to interact directly with smart contracts or maintain your own price feeds.
  • Multi-Chain Support: Query token prices across multiple EVM-compatible chains by specifying the token address, enabling cross-chain portfolio and DeFi analytics.
  • DEX-Aggregated Accuracy: Prices are calculated from Uniswap V3 and clone liquidity pools, ensuring accurate market-reflective valuations based on actual on-chain liquidity.
  • DeFi Application Integration: Ideal for wallets, dashboards, and DeFi protocols that need up-to-date token valuations to display portfolio values or compute trade sizes.
  • Lightweight & Fast: A simple single-parameter GET request returns structured pricing data with timestamps, making it easy to integrate into any application or automated workflow.

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/evm/price-current"
);
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/evm/price-current")
        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.
