Frequently Asked Questions
What sources does TrendPulse use?

Four public, free APIs: Wikimedia Pageviews (yesterday's top Wikipedia articles by region), Hacker News Firebase API (real-time top/new/ask/show/job stories), GitHub Search API (top new repos this week by stars), and Reddit JSON API (hot posts from r/technology, r/worldnews, etc.).

How does the category filter work?

Each source card is tagged with a category (News, Tech & Dev, Security, Tools & AI, Science). Clicking a category shows only the cards relevant to that topic. "All" shows every source. The Security card specifically filters HN stories and Reddit for CVE, vulnerability, breach, and exploit keywords.

Does the region filter affect all sources?

Region only affects Wikipedia, which switches to the relevant language edition (e.g. Nepali Wikipedia for NP, Bengali for BD). Reddit shows a mix of regional and global subreddits based on region. Hacker News and GitHub are global English sources unaffected by region.

Does this tool store my data?

Nothing is stored. All API calls are made directly from your browser — no proxy server, no analytics on your usage. Reddit requests may fall back to a public CORS proxy if the direct request is blocked.

How fresh is the data?

Wikipedia page-view data reflects yesterday's counts (updates daily). Hacker News, Reddit, and GitHub data update continuously — hitting Refresh always fetches the latest.

What if a source fails to load?

Each source fails independently. Wikipedia falls back to a curated regional list. Reddit tries multiple endpoints automatically before showing an error. For other sources, a clear error message is shown — this is usually a temporary API or network issue. Try refreshing.
