Details
The author built the Web Content Extractor API to provide a simple, fast, and cost-effective solution for developers who need to extract structured data from web pages. The API automatically detects the content type (article, product, recipe, job posting, event) and returns clean, organized JSON data including metadata, headings, images, and links. This addresses the common pain point of needing the main content from a URL, without the complexity of building custom web scrapers or using expensive third-party services. The API can process URLs in 1-3 seconds for just $0.003 per extraction, making it suitable for use cases like RAG pipelines, news aggregation, competitive intelligence, and content repurposing. It also supports batch processing of up to 25 URLs in parallel.
