Use with the REST API

The Serverless Hosted API V2 has one endpoint for all models and Workflows:

https://serverless.roboflow.com

This is in contrast to the V1 API which had many different endpoints based on the type of models being inferred.

Model Type	Serverless Hosted API V2	Hosted API V1
Object detection, Keypoint detection	https://serverless.roboflow.com	https://detect.roboflow.com
Instance Segmentation	https://serverless.roboflow.com	https://outline.roboflow.com
Classification	https://serverless.roboflow.com	https://classify.roboflow.com
Semantic Segmentation	Currently not supported	https://segment.roboflow.com
Foundation models (i.e. CLIP, OCR, YOLO-World)	https://serverless.roboflow.com	https://infer.roboflow.com

Make Requests with the Python SDK

If you are working in Python, the most convenient way to interact with the Serverless API is to use the Inference Python SDK.

To use the SDK, first install it:

pip install inference-sdk

To make a request to the Serverless Hosted API V2, use the following code:

from inference_sdk import InferenceHTTPClient

CLIENT = InferenceHTTPClient(
    api_url="https://serverless.roboflow.com",
    api_key="API_KEY"
)

result = CLIENT.infer(your_image.jpg, model_id="model-id/1")

Above, specify your model ID and API key.
