Use cases, market research, legality, and ethics.
Scraping for Journalists reviewed in 2026: the shipping edition dates from June 2017, ScraperWiki Classic is defunct, morph.io and OpenRefine still work, and the Python half needs porting.
Bulk-schedule a blog archive to X: sitemap and RSS extraction in Python, X API prices read on 13 August 2026 ($0.015 a post, $0.20 with a link), the daily posting caps, and the rules that make evergreen recycling a policy problem.
Social media scraping rechecked on 13 August 2026: official API prices and quotas for X, Reddit, YouTube, Meta, TikTok and LinkedIn, verified tool pricing, and what US and EU law actually permits.
Where to get stock market data: free API limits and licence terms read from the vendors in August 2026, what an exchange feed actually costs per user and per server, and how to store prices without losing precision.
Where to get weather data: free tiers and per-call prices read from each vendor's own pricing page on 13 August 2026, the OpenWeather One Call 4.0 change, and code in Python, JavaScript, PHP, and Go.
Scraping data, selling scraped data and coding a scraper for a client are three different legal questions with three different answers.
