You can access the knowledge graph data using:
  • REST API: Authenticate and make HTTP requests to retrieve academic standards directly. Best for applications that need real-time access. Learn more about the API.
  • MCP Server: Using the server, AI models can reliably work with academic standards, learning components, and learning progressions. They can resolve standards, decompose them into granular learning components, and trace progressions across standards. Learn more about the MCP server.
  • Local JSONL: Download local JSONL files and query them directly. Best for offline access, custom processing, or complex queries.
Use the tabs below to follow the quickstart for the REST API or Local JSONL approaches.

Early access
The API is in early access and is actively evolving. We will continue expanding it, and breaking changes may occur as we improve accuracy and reliability. Email support@learningcommons.org ↗ with your feedback or issues.

​
What you’ll do

  • Authenticate using an API key.
  • Get a standards framework identifier (CASE UUID) for Multi-State Mathematics.
  • Retrieve a list of academic standards using that framework identifier.

​
What you’ll need

​
Base URL

All REST API requests should be sent to the base URL provided in the Learning Commons Portal when you create your API key. The base URL will follow this format:
https://api.learningcommons.org/knowledge-graph/v0

​
Authentication

Include your API key in the x-api-key header on every request.
x-api-key: YOUR_API_KEY
Your API key will be securely shared with you through the Learning Commons Portal.

​
STEP 1: Get a standards framework identifier

Use your preferred HTTP client to send a GET request to the standards frameworks endpoint to get the CASE UUID for Multi-State Mathematics.
curl -X GET \
  -H "x-api-key: YOUR_API_KEY" \
  "https://api.learningcommons.org/knowledge-graph/v0/standards-frameworks?academicSubject=Mathematics&jurisdiction=Multi-State"
You should receive a 200 response with the CCSS Math framework for Multi-State, including the framework name, jurisdiction, adoption status, and a caseIdentifierUUID (GUID). Copy the caseIdentifierUUID from the response, you’ll use it in the next step.

​
STEP 2: Retrieve academic standards

Use the caseIdentifierUUID you copied from Step 1’s response with the academic standards endpoint to retrieve the individual standards for that framework.
curl -X GET \
  -H "x-api-key: YOUR_API_KEY" \
  "https://api.learningcommons.org/knowledge-graph/v0/academic-standards?standardsFrameworkCaseIdentifierUUID=YOUR_UUID_FROM_STEP_1"
If you skipped Step 1, you can use the CCSS Math framework UUID:c6496676-d7cb-11e8-824f-0242ac160002 in place of YOUR_UUID_FROM_STEP_1.
You should see a paginated list of academic standards aligned to that framework, including statement codes, descriptions, grade levels, and subject information.It should look similar to this:
