Welcome to the OpenScan APIs documentation 🚀.

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

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

### API Endpoints <a href="#api-endpoints" id="api-endpoints"></a>

> 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.

OpenScan offers 2 types of API plans, a set of free **community endpoints** and **API PRO**(Coming soon) which consists of additional derived blockchain data.

### Tutorials <a href="#tutorials" id="tutorials"></a>

> There is an overwhelming amount of data 📈 that can be extracted from the XDC Network 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.
