I want a robust Python script that speaks directly to TikTok’s private API through pure requests—absolutely no Selenium, Puppeteer, or browser emulation. Speed and scale are critical: the program must juggle at least 2,000 accounts at once, so efficient multi-threading (or an async approach) is a must. Core feature set • Mass Follow is the first priority, followed by Like, View, Share, and Save actions. • Dynamic device fingerprinting has to be built in so each request looks like it’s coming from a fresh, believable device profile. • The script will route traffic through rotating residential proxies; please factor IP rotation, back-off handling, and health checks into your architecture. • Only basic logging of actions is required—enough to verify what happened without generating bulky log files. Development expectations • Requests or httpx for traffic, no web-drivers. • Lightweight, modular code that I can extend later. • Clean separation between config (accounts, proxy pool, action mix) and engine logic. • Fully commented source code; I will own 100 % of the deliverable. • A concise README with setup steps and command examples. When you reply, include: 1. A fixed-price quote split into milestones (e.g., core engine, fingerprint module, final polish). 2. A short demo or repo link that proves you have already automated a major platform via raw HTTP calls. If you can hit the performance target and keep the code elegant, let’s get started.
