Quickstart Guide
Getting Started
This is a quick start guide for the OKLink Explorer APIs. Quickly learn how to create an account, generate API keys, and perform authentication to build customized applications using our APIs.
Visit the OKLink official website and register using your email or phone number.
After successful registration, log in using your email or phone number.
Go to the API management page and create your API keys.
Use the API keys to start exploring on-chain data with OKLink Explorer APIs.
API authentication
API keys are unique identifiers used to access API endpoints. All OpenAPI endpoints require API key authentication for access. You can create up to 5 API keys based on your needs. For your data security, do not share your API key with anyone.
API request URL:
- https://www.oklink.com/
Usage of API keys:
- For each API request, you need to add "Ok-Access-Key" in the HTTP Request Headers followed by your API key.
Examples of API interface calls:
- The following code snippets provide examples of calling the API in various languages, including cURL, Python, JavaScript - jQuery, Go, Java - OkHttp, PHP, and Rust to help you get started quickly.

Developer tools
Retrieve detailed information on address and token authorizations. Utilize API tools for domain risk detection, on-chain transaction broadcasting, and contract verification for both proxy and standard contracts.
Contract verification
Source code verification provides a way for projects to open source their smart contract code for end users to inspect and verify that it does what it claims to do and improve the transparency.
Endpoints of the "Contract verification" module support submitting contract source code for contract verification, verifying proxy contracts, and querying the contract ABI and source code of already verified contracts.
Verify contract source code
By uploading the contract source code, OKLink explorer will match the compiled contract bytecode with the bytecode on the blockchain and display it on the contract page of the explorer.
You can use this endpoint to quickly verify contracts and improve verification efficiency. The average processing time for contract verification is between 30-60 seconds.

Contract verification plugin
OKLink supports contract verification using third-party plugins such as hardhat and truffle and foundry, greatly improving your contract verification efficiency.
The supported chains include ETH, XLAYER, XLAYER_TESTNET, BSC, POLYGON, AVAXC, FTM, OP, ARBITRUM, LINEA, MANTA, CANTO, BASE, SCROLL, OPBNB, POLYGON_ZKEVM, SEPOLIA_TESTNET, GOERLI_TESTNET, AMOY_TESTNET, MUMBAI_TESTNET, POLYGON_ZKEVM_TESTNET
Contract verification using Hardhat
Method 1 (recommended): Verify by @okxweb3/hardhat-explorer-verify plugin
1、Install the Plugin: To install this plugin in your Hardhat project, use the following command:
npm install @okxweb3/hardhat-explorer-verify
2、Configure Hardhat: In your Hardhat configuration file (usually hardhat.config.js or hardhat.config.ts), import and configure the plugin. Ensure your network configuration and API keys are correctly set.
Example：
import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";
import '@okxweb3/hardhat-explorer-verify'; // Import the plugin
const config: HardhatUserConfig = {
solidity: "0.8.24",
sourcify: {
enabled: true,
},
networks: {
xlayer: {
url: "https://xlayerrpc.example.com",
accounts: ["<Your Wallet Private Key>"],
},
},
etherscan: {
apiKey: '...'
},
okxweb3explorer: {
apiKey: "<Your API Key>",
customChains: [
{
network: "Fractal Bitcoin Mainnet",
chainId: 70000061,
urls: {
apiURL: "https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/FRACTAL",
browserURL: "https://www.oklink.com",
}
}
]
}
};
export default config;
Custom chains can be configured based on the chains supported in openAPI https://www.oklink.com/docs/zh/#quickstart-guide-list-of-supported-chains).
customChains: [{
network: "chainName",
chainId: {chainId},
urls: {
apiURL: "https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/{chainShortName}",
browserURL: "https://www.oklink.com",
}}]
3、Verify Contracts: After deploying the contracts, use Hardhat to run the verification script. This typically involves running a specific Hardhat task that automatically fetches contract data and submits it to the OKLink blockchain explorer for verification.
Example command:
npx hardhat okverify --network xlayer <Your Contract Address>
4、View Verification Results: Once verification is successful, you can view the verification status and the contract code on the OKLink blockchain explorer.
5、Verify TransparentUpgradeableProxy Contract
Example command:
npx hardhat okverify --network xlayer --contract <Contract>:<Name> --proxy <address>
--proxy: mention it's a proxy contract address.- Note: If using 897 Contract, don't add
--proxy. Directly usenpx hardhat okverify --network xlayer --contract <Contract>:<Name>
You can view detailed usage and instructions in https://github.com/okx/hardhat-explorer-verify
Take the ETH chain as an example:
module.exports = {
...
etherscan: {
apiKey: {OKLink API key},
customChains: [
{
network: "eth",
chainId: 1,
urls: {
apiURL: "https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/eth",
browserURL: "https://www.oklink.com",
}
}
]
}
};
Method 2: Verify by making the following modifications to the hardhat.config.js file:
- Set the apiKey to your OKLink API key, which can be obtained from My account - API management on https://www.oklink.com/.
- Set the network to the blockchain network you have added.
- Set the chainId to the ID of the chain.
- Set the apiURL in the urls to https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/{chainShortName}, you can find the {chainShortName} of different chains here, and set the browserURL to https://www.oklink.com.
Contract verification using foundry
Apply for OKLink API key: https://www.oklink.com/docs/en/#quickstart-guide-getting-started
Verify a contract with the forge verify-contract command. You must provide:
- the contract address
- the contract name or the path to the contract
: - verify-url OKLink verify API url: https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/{chainShortName}, {chainShortName} is the short name of the chain, you can see the short name of the supported chain at here, explorerUrl is https://www.oklink.com
- your OKLink API key
full APIkey example：
forge verify-contract <the_contract_address>
src/MyToken.sol:MyToken
--verifier oklink
--verifier-url https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/eth
--api-key oklinkApiKey
Check verification result
It is recommended to use the --watch flag along with verify-contract command in order to poll for the verification result.
If the --watch flag was not supplied, you can check the verification status with the forge verify-check command:
example：
forge verify-check --chain 11155111 --verifier oklink --verifier-url https://www.oklink.com/api/explorer/v1/contract/verify/async/api/ethsepolia --api-key <your_OKLink_api_key> <GUID>
Contract verification using truffle
Take the ETH chain as an example:
plugins: ['truffle-plugin-verify']
oklinkVerify: {
provider: () => new HDWalletProvider(privateKey, infuraUrl), // Localhost (default: none)
gas: gasAmount,
network_id: 1,
verify: {
apiUrl: 'https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/eth@truffle',
apiKey: '{OKLink API key}',
explorerUrl: 'https://www.oklink.com/',
}
},
To verify a contract using truffle plugin, you need to add the following content to the module.exports module in the configuration file:
- Set the apiKey to your OKLink API key, which can be obtained from My account - API management on https://www.oklink.com/.
- Set the network_id to the ID of the chain.
- Set the apiURL in the urls to https://www.oklink.com/api/v5/explorer/contract/verify-source-code-plugin/{chainShortName}@truffle, you can find the {chainShortName} of different chains here, and set the explorerUrl to https://www.oklink.com.

Webhook test demo
Test whether the webhook monitoring task can receive data
- Test webhooks with Ngrok
- Sign-up for a free Ngrok account.
- Install Ngrok using the Ngrok guide. On macOS run 'brew install ngrok'
- Connect your Ngrok account.'ngrok authtoken YOUR_AUTH_TOKEN'
- Start your local forwarding tunnel ：get webhook url (Forwarding)
Python Code Demo
from flask import Flask, request
app = Flask(__name__)
@app.route('/webhook', methods=['POST'])
def webhook():
data = request.get_json()
print(data)
return 'suucess'
if __name__ == '__main__':
app.run(port=8001, debug=True)
Once you have a URL to test your webhook,follow the steps below:
1.Create webhook listeners （use the url get from Ngrok）
2.Creat webhook monitoring taskCreate webhook listeners,use the starter code
Notice As an added security measure, you can ensure your webhook notification originates from OKLink by using one of the following IP addresses: '47.52.206.222'
