Input and Output

Learn how to configure Worker inputs and understand the output data structure.

Input

Each Worker accepts input that tells it what to do. You can run a Worker from the CoreClaw Console UI and configure the input using the auto-generated form:

Input configuration UI

Configuring input via the UI is equivalent to passing input parameters as JSON. You can click Batch Edit to conveniently enter a large number of parameters at once.

When running a Worker via API, you pass the same input as a JSON object. For the example shown in the screenshot above, the corresponding JSON input would be:

[
    {
        "lang": "en-US",
        "keyword": "711",
        "max_results": 20,
        "base_location": "New York",
        "max_reviews_per_place": 5
    }
]

Options — Build, Timeout, and Memory

As part of the input, you can also specify run options for your Worker, such as the script version, proxy node, timeout, and memory allocation.

Output Data

Worker output is structured data stored via push_data. The structure depends on the Worker’s purpose and is defined by the output_schema.json file.

Export Formats

In the Console you can export output data in eight formats:

Format	Best For
CSV	Spreadsheets and data analysis
JSON	Developers and API integration
JSONL	Line-delimited, stream-friendly pipelines
XLS	Legacy Excel workbooks
XLSX	Modern Excel workbooks
HTML	Viewable in any browser
XML	Legacy and enterprise pipelines
RSS	Feed readers and monitor-style integrations
