Api key auth Basic auth Bearer auth

Path parameters

  • inference_id string Required

    The inference Id

Query parameters

application/json

Body

  • input string | array[string] Required

    Inference input. Either a string or an array of strings.

    One of:
    string-1 string array-2 array[string]
  • input_type string

    The input data type for the text embedding model. Possible values include:

    • SEARCH
    • INGEST
    • CLASSIFICATION
    • CLUSTERING Not all services support all values. Unsupported values will trigger a validation exception. Accepted values depend on the configured inference service, refer to the relevant service-specific documentation for more info.


    The input_type parameter specified on the root level of the request body will take precedence over the input_type parameter specified in task_settings.

  • task_settings object

    Optional task settings
