# Testnet

We use our own testnet whose API node is hosted at <https://stacks-node-api.testnet.alexlab.co/>, with a few useful modifications (such as [puppet mode controller](http://127.0.0.1:5000/s/sPu0USrFZJvbjvTbkBTh/)) to the stock testnet deployment.

You can explore the state of the testnet at <https://explorer.testnet.alexlab.co/?chain=mainnet>.

Developers generally would interact directly with our contracts deployed on the testnet through the API node above, but we also make available <https://app.testnet.alexlab.co/> for those who would like to interact from a browser.

Please note the testnet may be reset from time to time for maintenance and other purposes. We try to minimise the frequency of these resets, but it can and does happen, so please do bear that in mind when interacting with our testnet.

For any questions / follow-ups, please use our Discord channel (<https://discord.gg/alexlab>).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.alexlab.co/developers/integrations/networks/testnet.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
