# Testnet

{% hint style="info" %}
As of March 2025, we have switched our testnet infrastructure to **testnet4** by default. testnet3 is not supported anymore.
{% endhint %}

You can use our [testnet](https://en.bitcoin.it/wiki/Testnet) instance for testing the API.

Testnet API root: <https://testnet-api.ordinalsbot.com>&#x20;

Web UI: <https://testnet.ordinalsbot.com>

Status: <https://testnet-status.ordinalsbot.com>&#x20;

Explorer: <https://testnet-explorer.ordinalsbot.com>.

All endpoints will work on the testnet environment. Just replace the API root with testnet API root.
