Amazon product data, one call away.

Hand us a list of ASINs and get a signed webhook when anything changes, or call it yourself: pulse sweeps 10,000 ASINs a call for 0.25 credit each, lite fills in what moved (delivery dates included), full builds what is new, and /v1/offers shows every seller. Pulse reports the lowest new price, which matches the buy box about 92% of the time; lookups that fail are refunded.

Up to 10,000 ASINs per call on pulse and 2,000 on the other tiers, de-duplicated for you; every ASIN comes back exactly once with a status. Delivery dates come with lite and full at no extra cost. Pulse reports offers, not the buy box: its lowest new price equals the buy-box price about 92% of the time. Call times are typical ranges for Amazon US and vary through the day; smaller calls are faster. Sellers other than the buy-box winner come from /v1/offers. No tier returns feature bullets.

Watchlists on Amazon

Hand us ASINs. Get webhooks when anything changes.

ASINs, a cadence from every 5 minutes, and a webhook URL. We run the ladder above for you — pulse on every run, lite on what moved, full once per new ASIN — and bill only the calls it makes.

Any cadence from 5 minutes
Every 5 minutes or once a day — up to every 7 days. We schedule, chunk and retry.
Pulse first, lite on change
Every ASIN is swept on pulse; only what moved is re-fetched on lite, plus a lite pass every 8th run to catch seller swaps.
Full once for new ASINs
Every ASIN gets one full fetch as its baseline, then joins the sweep.
Dead ASINs delisted
When Amazon says an ASIN is gone, we tell you and stop paying for it.
Signed webhooks
Every event carries an HMAC signature you verify with your webhook secret. Or pull changes any time.
Billed as the calls it runs
No watchlist fee. You pay the pulse, lite and full credits it spends.

Call strategy

Sweep on pulse. Spend where it moved.

Pulse on every cycle, lite only for what pulse says changed, full once per new ASIN — and offers when you are about to act.

Pulse sees the new-offer count and the lowest new price, which matches the buy box about 92% of the time. A seller swap at the same lowest price can slip past it, so if that matters, run a lite pass over everything at a slower cadence.

FAQ

Amazon questions

Which Amazon marketplaces are supported?

Amazon US ("us", USD) today. Amazon UK, Amazon Germany, Amazon France, Amazon Italy, Amazon Spain, Amazon Canada, Amazon Mexico, Amazon Japan, Amazon Australia, Amazon India, Amazon Brazil, Amazon Netherlands, Amazon Sweden and Amazon Poland are announced as coming soon. "marketplace": "us" is the default.

What ASIN do I send?

10 letters or digits, e.g. B0009KNLV6. Send them as "ids" (or "asins"). Duplicates are fetched and charged once; anything that is not an ASIN is rejected with a 400 before anything is charged.

How is it billed?

Pulse: 0.25 credit per ASIN, up to 10,000 a call; Lite: 1 credit per ASIN, up to 2,000 a call; Full: 5 credits per ASIN, up to 2,000 a call. Items that come back ok or not_found are billed; partial and unavailable ones are refunded, and a call is rounded up once.

Can I watch Amazon items?

Yes. Create a watchlist with "platform": "amazon" and your ASINs; each run fetches what it needs at the platform’s prices and sends a signed webhook for every change, in the same event format as every other retailer.

Can pulse tell me the buy-box price?

Not directly. Pulse returns the new-offer count and the lowest new price. The lowest new price equals the buy-box price about 92% of the time, which is why it is a change detector, not a source of truth: re-fetch what moved on lite before you act, and never write back to a listing from pulse alone.

Can pulse detect a buy-box seller change?

Only when the offer count or lowest new price moves with it. To catch a seller swap at the same price, run a lite pass over everything at a slower cadence — daily, for example.

How are watchlists billed?

As the calls they run: 0.25 credit per ASIN per pulse sweep, 1 for each ASIN re-fetched on lite after a change or in the lite pass every 8th run (configurable), and 5 once for each new ASIN as its baseline. There is no per-watchlist fee, and every run in the dashboard shows the credits it spent.

Which tiers return delivery dates or other sellers?

Lite and full return the buy box's delivery dates (standard and fastest, cost, order-by time, Prime) at no extra cost; pulse does not. Sellers other than the buy-box winner come from /v1/offers. No tier returns feature bullets.

What does a failed lookup cost?

Nothing. partial and unavailable ASINs are refunded. A malformed request — bad tier, more than the per-call limit — is rejected with a 400 before anything is charged.
