langchain_community.utilities.apify.ApifyWrapper¶

class langchain_community.utilities.apify.ApifyWrapper[source]¶

Bases: BaseModel

Wrapper around Apify. To use, you should have the apify-client python package installed, and the environment variable APIFY_API_TOKEN set with your API key, or pass apify_api_token as a named parameter to the constructor.

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

Run an Actor on the Apify platform and wait for results to be ready. :param actor_id: The ID or name of the Actor on the Apify platform. :type actor_id: str :param run_input: The input object of the Actor that you’re trying to run. :type run_input: Dict :param dataset_mapping_function: A function that takes a single

dictionary (an Apify dataset item) and converts it to an instance of the Document class.

Parameters

  • build (str, optional) – Optionally specifies the actor build to run. It can be either a build tag or build number.

  • memory_mbytes (int, optional) – Optional memory limit for the run, in megabytes.

  • timeout_secs (int, optional) – Optional timeout for the run, in seconds.

  • actor_id (str) –

  • run_input (Dict) –

  • dataset_mapping_function (Callable) –

Returns

A loader that will fetch the records from the

Actor run’s default dataset.

Return type

ApifyDatasetLoader

Run a saved Actor task on Apify and wait for results to be ready. :param task_id: The ID or name of the task on the Apify platform. :type task_id: str :param task_input: The input object of the task that you’re trying to run.

Overrides the task’s saved input.

Parameters
