The `/json` endpoint extracts structured data from a webpage. You can specify the expected output using either a `prompt` or a `response_format` parameter which accepts a JSON schema. The endpoint returns the extracted data in JSON format. By default, this endpoint leverages [Workers AI](/workers-ai/). If you would like to specify your own AI model for the extraction, you can use the `custom_ai` parameter.
