Price-monitoring SaaS starts at $99/month for 100 products — and charges +20% of that again just to unlock its API. This kit watches prices the compliant way: a tested script that talks only to eBay's official Browse API on your own free keyset, a ToS compliance guide that quotes the platform rules verbatim, and the decision layer — matching rules, alert thresholds and a repricing playbook — that $99/mo tools don't include. One payment of ฿990 — less than nine days of the alternative — then it's free forever.
Get the kit — ฿99010 files in one zip — no scraping, no anti-bot tricks, nothing behind other people's logins. It runs on your own free API keys, in your own name.
What each source allows and forbids, with the official rules quoted verbatim — platform APIs, published feeds, brand MAP portals, your own seller account. Checked September 2026, with links to re-verify yourself.
ebay-price-watch.py talks only to the official eBay Browse API: OAuth, keyword + GTIN search, landed-price math, 429-safe retry, and MAP / margin / velocity alerts. Python 3, standard library only — nothing to install.
When two listings are truly "the same product" — plus MAP / margin / velocity alert rules and a weekly review routine. The judgment layer that turns price data into decisions.
Match, hold, differentiate or exit — a decision table for every price move you'll see, so a rival's discount doesn't become your margin's funeral.
A price history log and a margin calculator that work together: paste what the script logs, and watch your landed cost, margin and floor price update instantly.
A ready-to-fill watchlist.csv, a 14-day plan from install to a weekly pricing habit, and a buyer README in English and Thai. Single-business commercial license included.
Coverage is narrower than scrapers, by design. If a marketplace offers no feed or official API, this kit doesn't watch it. That is not a missing feature — it's the product. Scraping-based tools promise "everything" and deliver stale data and wrong prices, with recurring complaints in reviews, because anti-bot blockers break them every week.
eBay is scripted today. Shopee and Lazada run official Open Platforms — the compliance map covers them as allowed sources, and v1.x updates will follow as they're proven in sandbox. No market-wide promises before then.
You need 15 minutes of setup. You register your own free eBay keyset — that's the compliance model working: the system runs on official rails, in your own name, with no vendor in the middle.
No scraping, no anti-bot evasion, no monitoring behind other people's logins — not as a feature list, as a red line. Your store account and IP never appear in a ToS case.
Four sellers who get their money's worth in the first week.
The monitoring SaaS floor is $99/month for 100 products — plus 20% to unlock its API. ฿990 once ≈ nine days of that billing cycle. Then $0 forever, on your own keys.
A sourced, timestamped price log is proof of who broke MAP — collected through official channels, so your own compliance is never in question. The kit alerts you when any watched price crosses your MAP line.
No accessible price tool reads the SEA market — and the scraping ones carry ban risk. Start the official-API route on eBay today; the Shopee/Lazada paths are mapped as the next updates. A Thai quickstart is inside.
Bans, stale data, gray-area features like protected-site scanning and monitoring behind someone else's login. If your account survived that, don't gamble it again — start compliant, with receipts for every price you log.
No monthly plan, no product quota, no API surcharge, no subscription.

A single-business commercial license: one buyer (a person or a company) can use the kit for their own store — unlimited products, unlimited watchlists. Redistributing or reselling the kit files themselves is not allowed. Every price log you build belongs to you entirely.
Yes — every v1.x update (new scripted sources, refined matching rules, workflow improvements) is free. Re-download any time from your download page with your email and password. The Shopee/Lazada sandbox work ships as v1.x updates first — if a v2.0 ever ships, existing buyers get a clear upgrade path, never a surprise paywall.
If the kit doesn't fit how you work, email zicula06@gmail.com within 14 days of purchase and we'll refund you in full — the zip is yours to keep or delete. One refund per purchase; we only ask for optional feedback.
The watch script covers eBay's official Browse API out of the box — tested against a mock server, 22/22 checks passed. Shopee and Lazada both run official Open Platforms: the compliance map already covers them as allowed sources, and they'll be added as the cross-seller read scope is proven in sandbox — shipped as free v1.x updates. Nothing market-wide is promised before it's proven.
Yes — yours, and the free tier is enough. You register your own eBay developer keyset (about 15 minutes); the script then runs on official rails in your own name. No data broker, no shared quota, no +20% surcharge to touch your own data.
