Web data API that turns any site into clean, AI-ready content
Multiple endpoints cover discovery, single-page extraction, whole-site crawling, and URL mapping from one API.
Returns Markdown, structured JSON, HTML, links, and screenshots while stripping navigation, ads, and footers to cut token usage.
After scraping, drive clicks, typing, scrolling, and navigation with prompts or code to reach data behind interaction.
Python and Node SDKs, REST API, CLI, and an MCP server let agents and IDEs connect in minutes.

Get paid to train the next generation of AI models
After skill screening, contributors are matched to projects that fit their domain, from coding and math to linguistics and medicine.
No minimum hours and fully remote work, so experts can fit tasks around study, research or a primary job.
Typical work includes writing hard prompts, producing grading rubrics, ranking competing answers and reviewing model reasoning.
Contributors are paid for approved work each week, with rewards that scale with the quality of their output.
