Bilibili: Easiest Chinese Platform to Scrape in Python
A 2026 technical walkthrough explains why Bilibili is unusually easy to scrape compared with other Chinese platforms. The author demonstrates a compact, 30-line Python scraper using plain HTTP (httpx/requests) to call stable JSON endpoints for search, video metadata, user uploads, trending lists and comments. Most public endpoints require no auth, browser emulation, or proxies; only the comments endpoint is throttled for datacenter IPs and may require authenticated cookies or residential IPs for full pagination. The post lists the engagement metrics available (views, likes, shares, replies, plus Bilibili-specific danmaku, coins and favorites), provides measured performance numbers from Apify serverless runs, and notes a hosted Apify actor (zhorex/bilibili-scraper) that handles WBI signing for search and offers paid usage.
Practical technical guidance for Chinese-market monitoring and creator analytics; useful for marketers and data teams but not industry-shifting.

Key Takeaways & Evidence Grounding
- Bilibili exposes stable JSON HTTP endpoints for search, video metadata, user info, trending/popular feeds and comments.
- Plain HTTP libraries (httpx/requests) work on most Bilibili endpoints; no TLS fingerprinting or headless browser required for public data.
- The comments endpoint (/x/v2/reply/main) is throttled from datacenter IPs; full comment pagination requires authenticated session cookies or residential IPs.
- Author provides a 30-line Python scraper example and performance benchmarks from Apify serverless (256MB RAM).
- A hosted Apify actor (zhorex/bilibili-scraper) supports the five scraping modes, has 16 users, 9 monthly active users, 2,635 extractions and a pricing example of $5 per 1,000 results.

Weibo as Alt-Data: Python Guide for China Funds
A technical how‑to shows how China‑focused funds can convert public Weibo activity into low‑cost alternative data using an Apify Actor (zhorex/weibo-scraper) and simple Python code. The article identifies three valuable signals — Weibo’s hot‑search board, keyword/cashtag sentiment, and KOL post monitoring — and demonstrates cron-based scraping patterns, reach-weighting of posts, and joining feeds (Weibo + Xueqiu) for consumer and investor sentiment. It describes pricing as pay‑per‑result (cents per run), gives example code snippets, and lists other Apify actors for Chinese platforms (Xueqiu, Xiaohongshu/RedNote, Bilibili, Chinese Brand Monitor). The author notes limitations (not real‑time tick data, public surface only, no sentiment model included) and provides implementation guidance for building daily alt‑data jobs and velocity-based signals.
Bilibili Loader Engineering: DASH, M4S, FFmpeg
This developer guide explains the engineering behind a high-performance Bilibili video downloader. It covers Bilibili’s dual ID systems (legacy AV and newer BV) and the bidirectional BV↔AV conversion algorithm required to resolve video metadata. The article details Bilibili’s DASH-based delivery where audio and video are served as separate .m4s segments, requiring playurl API queries to obtain matching audio/video URLs and parallel downloads. It describes aggressive CDN protections that trigger 403 responses and the workaround tactics used (Referer header, User-Agent rotation, and SESSDATA session cookies). Backend architecture uses Python/Django with httpx and asyncio for I/O-bound concurrency; final media assembly uses FFmpeg stream-copy (-c copy) to mux .m4s tracks into .mp4 without re-encoding.
Apify Actor Replaces Custom TikTok Scrapers
A SIÁN Agency developer published a technical guide (Apr 27, 2026) describing how they replaced custom TikTok scrapers with a five-line Python call to an Apify actor. The article explains common failure modes of homegrown scrapers (layout drift, auth/rate-limits, audio extraction/transcription) and demonstrates calling the actor sian.agency/best-tiktok-ai-transcript-extractor via the ApifyClient. The actor accepts two input keys (tiktokUrl, bulkUrls), returns an AI transcript per video plus ~45 metadata fields, and offers a free tier (5 videos/run, 8s delay) with a paid bulk mode for larger volumes. The author argues using a maintained SaaS actor reduces maintenance overhead compared with operating your own Playwright/Whisper/ffmpeg pipeline.
