Querying an endpoint

Once the endpoint has finished updating:
endpoint.update(model_version, strategy, wait=True)
Users can make queries to it. This tutorial will explore several ways to do this, using the client and CLI.

Using the client

Given an endpoint (which has a model deployed to it), we can make queries as follows:
deployed_model = endpoint.get_deployed_model()
results = deployed_model.predict(test_data)
We can also make queries via cURL requests. An example request is given in the string representation of the endpoint object:
print(endpoint)
# This should print out similar to:
# path: <some-path>
# id: <some-id>
# curl: curl -X POST <prediction-url> -d '' -H "Content-Type: application/json"
# ...

Endpoint metadata

Endpoint query responses will contain metadata about the endpoint configuration in the response headers. For example:
$ curl -H "Access-token: a1b2c3d4-e5f6-a7b8-c9d0-e1f2a3b4c5d6" -X POST https://myenv.verta.ai/api/v1/predict/my-endpoint -d '""' -H "Content-Type: application/json" -i
