Olostep
Olostep is a web-data API platform built for AI and developer use, enabling fast, reliable extraction of clean, structured data from public websites. It supports scraping single URLs, crawling an entire site’s pages (even without a sitemap), and submitting batches of up to ~100,000 URLs for large-scale retrieval; responses can include HTML, Markdown, PDF, or JSON, and custom parsers let users pull exactly the schema they need. Features include full JavaScript rendering, use of premium residential IPs/proxy rotation, CAPTCHA handling, and built-in mechanisms for handling rate limits or failed requests. It also offers PDF/DOCX parsing and browser-automation capabilities like click, scroll, wait, etc. Olostep handles scale (millions of requests/day), aims to be cost-effective (claiming up to ~90% cheaper than existing solutions), and provides free trial credits so teams can test its APIs first.
