Barchart.com XSRF-Token Cookie Flow Change Breaks Existing Scraping Script
A previously working Python script that scraped Barchart.com market data now fails because the site no longer returns the XSRF-TOKEN cookie needed to authenticate the API request. The user cannot locate a replacement token in the page, illustrating the fragility of unofficial scripts against undocumented site-side auth changes.

Similar Problems
surfaced semanticallyBrowser Cookies Do Not Transfer to Python Requests for API Access
Automating authenticated web scraping by extracting browser cookies and reusing them in Python requests fails with 403 errors. Session cookies from Playwright do not transfer cleanly to the requests library for protected API endpoints.
Session Cookie Auth Fails When Replicating Browser Requests in Python
A developer scraping a Keycloak-based SSO portal can authenticate via browser and curl with captured session cookies, but the same request fails with 403 Forbidden when replicated in a Python requests session. The issue is specific to this university's SSO implementation and session-handling quirks rather than a general API limitation.
Cloudflare Bot Detection Blocks Legitimate Programmatic API Requests
Developers making HTTP requests from code (VB.NET, C#, Python) to endpoints protected by Cloudflare are blocked even when the same request works fine in a browser. Cloudflare fingerprints far more than the user-agent — TLS handshake, header ordering, and browser entropy — making legitimate automation extremely difficult without emulating a full browser runtime.
Instagram Scraping Tool Broken by Platform-Side Anti-Bot Redirects
Users of a command-line media downloader are unable to fetch Instagram posts because the platform now redirects scraping requests to the home page, triggering extraction failures. The issue affects multiple operating systems and only impacts post downloads, while other content types like highlights still work. It highlights the fragility of tools that depend on reverse-engineering a platform's undocumented behavior.
E-Commerce Anti-Bot Detection Blocks Web Scraping Despite Premium Proxies
A developer scraping Shopee product data repeatedly hits a verify-traffic anti-bot error that redirects requests to a login wall, even when using ISP or premium residential IPs with Playwright. This reflects the broader difficulty of reliably bypassing e-commerce anti-scraping defenses, which persists despite paying for higher-quality proxy infrastructure.
