DeepInfra supports the OpenAI embeddings API for all embedding models. The endpoint is: 
POST https://api.deepinfra.com/v1/openai/embeddings

​
Example

from openai import OpenAI

openai = OpenAI(
    api_key="$DEEPINFRA_TOKEN",
    base_url="https://api.deepinfra.com/v1/openai",
)

input_text = "The food was delicious and the waiter..."
# Or a list: ["hello", "world"]

embeddings = openai.embeddings.create(
    model="Qwen/Qwen3-Embedding-8B",
    input=input_text,
    encoding_format="float"
)

print(embeddings.data[0].embedding)
print(embeddings.usage.prompt_tokens)

​
Batch embeddings

Pass an array as input to embed multiple texts in a single request: 
embeddings = openai.embeddings.create(
    model="Qwen/Qwen3-Embedding-8B",
    input=["Hello", "World", "How are you?"],
    encoding_format="float"
)

for i, item in enumerate(embeddings.data):
    print(f"Text {i}: {item.embedding[:5]}...")  # First 5 dims
