QueryScrape AI is a web scraping API that extracts structured data from websites without relying on CSS selectors or XPath expressions. The service accepts a URL and a user-defined JSON schema, then uses a headless Playwright browser to render the page, execute JavaScript, and extract content. The extracted data is validated against the provided schema and returned as structured JSON output. The API is powered by Google's Gemini 2.5 Flash model, which interprets page content visually and textually to adapt to frontend changes automatically. Key features include selector-free extraction, JavaScript rendering for single-page applications, schema-enforced output that produces Pydantic-shaped JSON, and a built-in crawler for recursive page scanning. The service also includes an interactive extraction playground for testing configurations, a visual overlay feature that returns element screenshot coordinates, and a website protection analysis tool that checks for anti-bot systems such as Cloudflare, DataDome, and Akamai. Each extraction costs under $0.005, and the API includes 1,000 free extractions per month with a developer API key. Typical use cases involve integrating the API into data pipelines where website structures change frequently, requiring minimal maintenance. The workflow involves defining a JSON schema, providing a target URL, and receiving validated structured data that can be directly inserted into a database. The crawler configuration allows users to set parameters for recursive extraction, with the system initializing a link discovery queue to scan and extract data from multiple pages. The service is open source under the MIT License and is designed for developers building robust web data extraction systems.
