The URL Retriever is a versatile flow component designed to fetch and process web content from specified URLs, returning the information as structured documents. It serves as a bridge between external online content and your AI workflow, enabling you to integrate, analyze, or process web-based information efficiently.
What Does It Do?
This component retrieves the content of one or multiple URLs provided as input. It can extract the main text, metadata, and even process content from images using Optical Character Recognition (OCR). The retrieved data is then made available in various structured formats suitable for downstream AI tasks such as summarization, question answering, or knowledge extraction.
Input Options
You can supply URLs to the component in two ways:
Text URLs:
- Input Type:
Message - Description: A list of plain URL links for the component to fetch content from.
- Input Type:
URL Records:
- Input Type:
UrlRecord - Description: A list of structured URL records, which may include additional metadata.
