}Real response, trimmed for width. Add &mode=live to scrape on demand instead of reading cache.
Then click any product for its full history — price and rank over time, every seller on the listing, and who has held the buy box.
Paste any ASIN, or switch the marketplace dropdown to look the same product up elsewhere. Live responses from our production warehouse — observed snapshots, not Amazon's live feed. The demo is rate-limited per visitor; the API itself is not.

observed_aton every record, and credits charged in the response
Amazon US, UK, DE, CA, AU, JP, FR, IT, ES, MX, BR + US Walmart, in one schema. Amazon US has the deepest history; other marketplaces start when tracking began there.
Cached or live — you choose, per request.
mode=cache — the default
Answers from our warehouse, typically well under 100ms. Every record carries observed_at, so you can see exactly how fresh the snapshot is and decide for yourself — we don't ask you to take freshness on trust.
mode=live — when it has to be now
Fetches the product on demand. Slower than cache — it is a real page fetch, so expect seconds rather than milliseconds. Use it when the answer must be current to the minute. Failed fetches are never billed.
Same endpoint, same schema, one parameter. You are never locked into one or the other.
What it costs.
From $0.30 per 1,000 at volume. Start free with 2,500 credits and no card, then choose a monthly subscription (auto-renews, the most credits per dollar, credits valid 30 days) or a one-time pack you pay for by card — no account, no auto-renew, credits valid 90 days, at about 20% fewer credits for the same price. A cached product lookup is 1 credit — a simple, published cost, not a multiplier. Failed and partial requests are never billed.
