The Learning Commons API provides programmatic access to Knowledge Graph data:

* [Academic Standards](/knowledge-graph/graph-reference/academic-standards) – All 50 U.S. states
* [Learning Components](/knowledge-graph/graph-reference/learning-components) – Mathematics and English Language Arts
* [Standards Crosswalks](/knowledge-graph/graph-reference/standards-crosswalks) – Relationships between state standards and Common Core State Standards (CCSS)
* [Curriculum](/knowledge-graph/graph-reference/curriculum) – Scope and sequence

## How to use the API

|                    |                                                                                                                                                                                                             |

| **Base URL**       | `https://api.learningcommons.org/knowledge-graph/v0`                                                                                                                                                        |
| **Authentication** | Generate an API key in the [Learning Commons Platform](https://platform.learningcommons.org/?utm_source=docs\&utm_medium=api-reference) ↗ and include it in the request header as `x-api-key: YOUR_API_KEY` |
