Introduction

Welcome to the opBNB BscScan APIs documentation 🚀.

opBNB BscScan is the leading blockchain explorer, search, API and analytics platform for BNB, a decentralized smart contracts platform.

As a means to provide equitable access to blockchain data, we've developed the opBNB BscScan Developer APIs to empower developers with direct access to opBNB BscScan's block explorer data and services via GET/POST requests.

opBNB BscScan's APIs are provided as a community service and without warranty, so please use what you need and no more.

Source attribution via a backlink or a mention that your app is "Powered by opBNB BscScan.io APIs" is required except for personal/private usage.

API Endpoints

Your app may need to show a user's ERC-20 token holdings and their USD value 💰 , check if a transaction has been mined ⛏️ or get the latest gas price estimates ⛽ .

For that you may find a suitable endpoint from our wide range of APIs that you can simply query to provide data while you remain fully focused on building your applications.

opBNB BscScan offers 2 types of API plans, a set of free community endpoints and API PRO which consists of additional derived blockchain data.

Tutorials

There is an overwhelming amount of data 📈 that can be extracted from the BNB blockchain.

We've helped you take the first steps by writing some thorough tutorials on how to query and derive popular blockchain metrics.

For power users, we've also added guides such as how you can programmatically verify contracts through API calls and more advanced use cases of endpoints.
