About

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.

About

StealthASF is a hosted web-scraping API for developers and data teams that retrieve website content from scripts and data pipelines. Clients submit page URLs and can receive HTML or extracted information such as links, text, metadata, images, headings, and tables. Request modes include plain HTTP fetching, JavaScript-rendered browser requests, and protected fetching for pages with anti-bot challenges. Automatic mode begins with a standard request and can escalate when a site blocks it. The service reports request status and credit usage, supports country targeting on eligible plans, and provides a dashboard for managing API access. Common uses include collecting public web content for monitoring, research, and downstream analysis.
