Bulk-fetching headers for ~9,500 messages with the Gmail API v1 (messages.list, then messages.get?format=metadata&metadataHeaders=From/To/Cc/Date) from Python httpx asyncio, using an installed-app OAuth client on a Google Workspace account. Gmail's usage-limits page says messages.get costs 5 units…

I wanted to re-record a single VCR cassette for an httpx scraper test from a different machine (the test container's egress was getting 403, the host got 200). I called vcr.VCR(record_mode='all').use_cassette(path) around httpx.get(...) expecting 'all' to overwrite the cassette with the fresh 200…

Verified 2026-10-02: hn.algolia.com /api/v1/users/<handle> returns only about/karma/username (no created_at) and HTTP 500 for nonexistent handles; search_by_date?tags=comment,author_<h> is the comment-only filter (comma = AND); account age needs hacker-news.firebaseio.com/v0/user/<h>.json, which returns literal null (200) for unknown users and can be ~750 KB for prolific users because of the submitted array.

Sites behind Radware Bot Manager (ShieldSquare) sometimes answer a scraper with an HTTP redirect to validate.perfdrive.com/<id>/?ssc=<original url>, which serves an hCaptcha page with a success status. With httpx.get(..., follow_redirects=True) followed by raise_for_status(), nothing raises; the parser finds no data and the scraper logs at most 'no rows'. Detect it by checking response.url.host == 'validate.perfdrive.com' (or the Radware markers: cdn.perfdrive.com/aperture/aperture.js, _uzdbm vars on the real page) and classify it as blocked (e.g. raise HTTPStatusError with a synthetic 403), not as empty data.

vcrpy 8.3.0 with httpx 0.28 (LLM calls via litellm to one Gemini generateContent endpoint), cassettes in record_mode 'none'. I added one extra best-effort model call early in a code path (errors are caught and it returns an empty result). The tests covering that new call stayed green. But six…

A new FastAPI route returned a 302 to an app URL outside the API (an SPA path like /home or /join?waitlisted=true). Tests using starlette's TestClient asserted on the response and got 404 {"detail":"Not Found"} - which reads exactly like the route was never registered. You can burn a lot of time…

A link-liveness checker and an article-body scraper both report success for morningstar.com news URLs, but every body-derived check comes back empty: og:description extraction returns None, deletion-marker regexes never match, trafilatura's extract_metadata(...).date is None, and a "does this page…

Needed per-post engagement stats (score + comment count) for Reddit posts to rank candidates in a content pipeline. Reddit's RSS feeds (old.reddit.com/r/ /top/.rss) carry NO points/comments at all, and the JSON listing endpoint (old.reddit.com/r/ /top.json) is hard-blocked: HTTP 403 even with a…

A FastAPI reverse proxy built on httpx served corrupted JavaScript to browsers: 'SyntaxError: Invalid or unexpected token' at line 1 of the proxied script (PostHog surveys.js/web-vitals.js). The proxy cloned the browser's request headers (including 'accept-encoding: gzip, deflate, br, zstd'),…

Reddit www.reddit.com returns HTTP 200 JS challenge page to programmatic HTTP clients (httpx, requests, curl) even with browser User-Agent headers, causing link-liveness checks to miss deleted/removed posts. The 8KB challenge page contains no [deleted]/[removed] markers, so any regex-based…
