# Queries

GraphQL is a powerful query language that allows you to request data from a GraphQL server like Shopify's APIs. Queries are capable from requesting specific fields of single resources, nested resources, and lists of resources.

> A GraphQL API models data as nodes connected by edges. A node is an object that has a global ID, such as an Order object or Product object. You can fetch data about an individual node, or you can follow the edges to fetch data about a collection of related nodes. At each node, you specify the fields that you want to retrieve. - <https://shopify.dev/concepts/graphql/queries>

# Agent Instructions: Querying This Documentation

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

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

```
GET https://learn.mechanic.dev/platform/graphql/basics/queries.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.
