Data API Quickstart

Three steps to your first API response.

Step 1: Get your API key

Use the Get your key link in the top right to request access. We will set up your account and provide your subscription key. Include it in every request as a header:

Step 2: Search European law

Make your first search request. The keyword search endpoint accepts a query string and returns matching legal documents across your chosen jurisdictions.

curl -X POST 'https://api.moonlit.ai/v1.1/search/keyword_search' \
  -H 'Ocp-Apim-Subscription-Key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "query": "data protection",
    "jurisdictions": ["European Union"],
    "num_results": 5
  }'

Step 3: Retrieve a full document

Use the identifier from your search results to retrieve the full text, metadata, and AI-generated summary via a GET request with a query parameter.

curl "https://api.moonlit.ai/v1.1/document/retrieve_document?DocumentIdentifier=62018CJ0311" \
  -H "Ocp-Apim-Subscription-Key: YOUR_API_KEY"
