​
Overview

The Embedding API converts code and text into high-dimensional vectors that capture semantic meaning. Our latest morph-embedding-v3 model delivers state-of-the-art performance on code retrieval tasks, enabling powerful search, clustering, and similarity operations for code-related applications.

​
Endpoint Reference

from openai import OpenAI

# Initialize the OpenAI client with Morph's API endpoint
client = OpenAI(
    api_key="your-morph-api-key",
    base_url="https://api.morphllm.com/v1"
)

def get_embeddings(text: str) -> list[float]:
    response = client.embeddings.create(
        model="morph-embedding-v3",
        input=text
    )
    return response.data[0].embedding

# Example: Get embeddings for code chunks
def embed_code_chunks(code_chunks: list[str]) -> list[dict]:
    results = []

    for chunk in code_chunks:
        embedding = get_embeddings(chunk)
        results.append({
            "text": chunk,
            "embedding": embedding
        })

    return results

# Store these embeddings in a vector database of your choice
