# Built in Nodes

This section contains a listing of all modules and nodes available out of the box in Midio.

## Core/std

The [core/std](/midio-docs/built-in-nodes/core-std.md) package contains the most basic building blocks needed for most Midio applications, like nodes for working with [numbers](/midio-docs/built-in-nodes/core-std.md#math), [strings](/midio-docs/built-in-nodes/core-std.md#strings), [objects](/midio-docs/built-in-nodes/core-std.md#map) and [lists](/midio-docs/built-in-nodes/core-std.md#list), as well as operations related to [cryptographic hashing](/midio-docs/built-in-nodes/core-std.md#hashing-crypto), [JSON](/midio-docs/built-in-nodes/core-std.md#json) and [CSV](/midio-docs/built-in-nodes/core-std.md#csv) data, [writing tests](/midio-docs/built-in-nodes/core-std.md#testing), [working with time](/midio-docs/built-in-nodes/core-std.md#time), [scheduling](/midio-docs/built-in-nodes/core-std.md#scheduling), [tracing](/midio-docs/built-in-nodes/core-std.md#tracing), [regular expressions](/midio-docs/built-in-nodes/core-std.md#match), [image manipulation](/midio-docs/built-in-nodes/core-std.md#image), and much more.

## HTTP

The http package contains nodes for [making](/midio-docs/built-in-nodes/http.md#fetchurl), and [responding](/midio-docs/built-in-nodes/http.md#endpoint), to http requests, as well as related to these tasks, like [url-encoding](/midio-docs/built-in-nodes/http.md#urlencodestring).

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.midio.com/midio-docs/built-in-nodes.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
