Guides, research, and case studies on web scraping, price monitoring, and data delivery for analytics, marketing, and product needs.
Scrapy web scraping rechecked against Scrapy 2.17.0 on 13 August 2026: what scrapy startproject really sets, why TLS verification is off by default, why the SOCKS snippet fails, and measured queue memory per million URLs.
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.
Ready-made web scraping tools checked against vendor pricing pages on 13 August 2026: desktop crawlers, spreadsheet formulas, no-code clouds, scraping APIs and extensions, with derived cost per 1,000 pages from $0.45 to $36.75.
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.
Can client-side JavaScript read another site's HTML? Checked against the Fetch Standard, MDN and Chrome's own docs in August 2026: what the same-origin policy blocks, why no-cors gives you nothing, what CORS proxies cost, and the two places where browser-side extraction genuinely works.
HTTP sniffers compared in August 2026: browser DevTools, online checkers, packet capture and proxy debuggers, with current versions, verified prices, and what TLS 1.3 and HTTP/3 changed.
Every route to getting data off a website, compared: spreadsheet formulas, browser extensions, no-code platforms, Python and AI extractors, with vendor prices read on 13 August 2026 and a parser benchmark where the same page comes apart 23 times faster.
What data mining is, how the CRISP-DM cycle really runs, the core techniques, and what the tools cost: versions and prices read from vendor pages on 13 August 2026, plus a timed apriori-versus-FP-growth run.
Scraping data, selling scraped data and coding a scraper for a client are three different legal questions with three different answers. Re-read against the statutes and rulings in August 2026: hiQ's $500,000 judgment, Meta and X v. Bright Data, Reddit v. Perplexity, the CCPA/GDPR split on public data, and the tool-supply offenses that break the toolmaker analogy.
