 ## Using API
 
-You’ll be able to use the models through our API as well. The API is coming soon and will have some exciting features. Stay tuned!
+You can use the large model via our API as follows:
+
+```python
+from mixedbread_ai.client import MixedbreadAI
+
+mxbai = MixedbreadAI(api_key="{MIXEDBREAD_API_KEY}")
+
+res = mxbai.reranking(
+  model="mixedbread-ai/mxbai-rerank-large-v1",
+  query="Who is the author of To Kill a Mockingbird?",
+  input=[
+    "To Kill a Mockingbird is a novel by Harper Lee published in 1960. It was immediately successful, winning the Pulitzer Prize, and has become a classic of modern American literature.",
+    "The novel Moby-Dick was written by Herman Melville and first published in 1851. It is considered a masterpiece of American literature and deals with complex themes of obsession, revenge, and the conflict between good and evil.",
