Amazon & Trendyol Price and Buy Box Tracker

Track public Amazon and Trendyol product pages for price, seller, availability and Buy Box signals — and get the change since the last run, not just today's number.

Give it direct product URLs, or give it a search / listing URL and let it find the product links.

Trendyol note: Trendyol blocks data-center IPs. For Trendyol URLs set proxyGroups to ["RESIDENTIAL"], otherwise those pages come back as blocked (blocked pages are never billed). Amazon works with the default proxy.

What this does that a generic scraper does not

Every row carries its own history. previousPrice, priceChange and priceChangePercent are computed against the snapshot stored in the run's key-value store, so a scheduled run is a change feed, not a re-scrape. Point snapshotKeyValueStoreId at a named store to keep one history across runs.

Prices come out as numbers, in the right magnitude. "1.299,90" and "1,299.90" are parsed to the same amount. priceText keeps the original string so you can audit the parse.

A challenge page is never a price. Amazon and Trendyol return consent, captcha and bot-protection pages under load. Those become status: "blocked" and are never turned into a fabricated 0 or a stale number.

Proxy is on by default. Both marketplaces block most datacenter IPs. A direct request is tried first; if it is empty or challenged and useApifyProxy is on, the page is retried through Apify Proxy with rotation. RESIDENTIAL is the most reliable group for marketplace pages.

Discovery is bounded. Search / listing URLs contribute the product links found on the page, capped by maxProducts. The run never wanders past the cap.

Input

Field	What it does
startUrls	Direct Amazon / Trendyol product URLs
searchUrls	Search or listing URLs; product links on them are added, up to maxProducts
marketplace	auto, amazon or trendyol — filter seeds to one marketplace
maxProducts	Hard cap on unique product pages fetched (1–500)
requestTimeoutSecs	Per-request timeout (5–120)
includeUnchanged	Keep rows with no price / seller / Buy Box change
currency	Optional currency-code label; blank keeps the marketplace currency
snapshotKeyValueStoreId	Named KV store for cross-run price history; blank uses the shared default
useApifyProxy	Retry blocked pages through Apify Proxy (recommended on)
proxyGroups	Optional proxy groups such as RESIDENTIAL

Output

One row per product: identity, price / currency / priceText, seller / buyBoxSeller / isBuyBoxWinner, availability, rating, reviewCount, offersObserved, and the previousPrice / priceChange / priceChangePercent delta. Only pages that were read successfully become dataset rows. Blocked, unreadable or unsupported URLs are not added to the dataset; they are listed with a reason under failures (and rejected inputs under skippedInputs) in the SUMMARY record, so a run is always auditable. A failed page never overwrites the last good price in the history store. Only public amazon.* and trendyol.com URLs are accepted; duplicates of the same product are fetched once.

Limits, stated plainly

• No JavaScript rendering. Prices drawn purely client-side with no markup come back thin; status says not-found rather than guessing.
• Buy Box is a signal, not a scrape of the offer listing. buyBoxSeller mirrors the seller shown on the product page; offersObserved counts offer-bearing JSON-LD blocks.
• Discovery only sees links on the page given. It does not paginate a search result set.
• Use this Actor lawfully and respect each marketplace's terms, robots rules, rate limits and applicable competition / data-protection law.
