An ASIN Data API alternative with monthly plans and one-time top-ups.
ASIN Data API is a Traject Data product, and Traject Data is now part of ScraperAPI — asindataapi.com redirects into their site, which carries a ScraperAPI copyright. Plans start at a $19 monthly plan with an unconditional 14-day money-back — a credit allowance that renews each billing cycle, card checkout through Lemon Squeezy, cancel anytime. Subscribers can add top-ups at their tier's rate, usable over 90 days. Either way, one call answers product search and per-ASIN lookups from a maintained warehouse in under 100 milliseconds, with price, seller and BSR history in the same response. Try the live demo and time it yourself.

Search your own products. See what the API returns.
The demo doubles as a coverage check: enter one of your ASINs, a barcode, a keyword or an Amazon product link. A product we hold shows its full record and history; one we don’t hold yet is fetched live from Amazon.
The operator network behind a brand, live.
This is the real Nike seller network — every brand below shares Amazon buy-box sellers with Nike, drawn from our observed daily record. The Logimu API serves exactly this object: GET /v1/brand/network?brand=Nike&country=us returns the nodes[] and weighted edges[] you see drawn here, one credit per hop. Hover a brand for its numbers; click one to recenter; type any brand to map it.
Node colour is the brand’s heat (seller pressure: how many sellers per listing and how fast that is rising), size is its catalogue, distance is how many sellers two brands share. Counts and shares from observed buy-box data, refreshed daily — never estimates. Available on every paid plan. Endpoint reference →

No — running the job is the only way to price it |
| Bulk rows from the warehouse | Yes — rows within your max age serve at half a credit, each stamped with when it was observed | No warehouse — every row in a job is a live scrape |

Their list prices are taken from the published ASIN Data API plan table and were checked on 4 August 2026; their tiers are billed annually. Credits are not identical units across the two APIs — a warehouse product lookup costs 0.5 credits here and a product request costs one credit there — so the table compares the published price per 1,000 credits, which is the unit both of us bill in. Fair is fair on coverage: they reach Amazon India and we do not.
What the ScraperAPI acquisition changes.
Traject Data — which builds ASIN Data API, Rainforest API and BlueCart API — was acquired by ScraperAPI in 2026. ScraperAPI has said the Traject APIs are moving onto its own infrastructure and billing, so that customers manage everything from a single account. The standalone asindataapi.com now redirects to the Traject site, and that site carries a ScraperAPI copyright notice.
That is a normal thing for a company to do after an acquisition, and it may well work out fine for the people using it. It is also the moment when it costs you the least to check what else is available, because you are going to be looking at your integration and your bill anyway.
We are independently owned, we have run our own extraction infrastructure since 2013, and our pricing is on the pricing page rather than behind a sales conversation.
Migration is a schema map.
Send us the ASIN Data API request types you use — product, offers, search — and the fields you actually consume. We will map them onto our endpoints, hand you a key, and you can run both APIs side by side until you are satisfied. Most integrations swap over in an afternoon; the response shapes are close and ours is smaller.
What a product response includes.
One ASIN in, the full record out — /v1/product.
- Current snapshot Price, BSR, rating, review count, stock state, UPC, parent ASIN, brand stats — and Amazon's own "bought in past month" figure where it publishes one.
-
Every seller, in the same call
The full live offer list is standard, not a separate endpoint: seller name and ID, price, FBA and Prime flags, feedback score, and buy-box days. The buy box and the first offer page come by default;
full_offers=truewalks every further page inside the same call for the same single credit. Gathering offers is the slow part of any live scrape, which is why most APIs bill them separately — a paginated offers endpoint at a credit per page of 10 makes a 30-seller listing four requests there and one here. - Price and stock history The full price series plus price-change and stock-change events, in the base call.
-
Rank history, per category
Add
bsr_history=truefor daily rank in every category the product sits in. Included in the record, like the seller history below. -
Seller history — who held the buy box, and when
Add
offer_history=truefor a buy-box timeline plus a per-seller price series, each with first seen, last seen and buy-box days. Included in the record too. -
Warehouse or live scrape — your call
mode=cacheanswers in under 100ms for half a credit, batch or single call.mode=livescrapes the listing on demand when it has to be current, for one credit. Failed scrapes are never billed.
Eleven Amazon marketplaces plus US Walmart, in one schema.
Derived intelligence: what the observations add up to.
Every product we observe is also an observation about a brand, a seller and a category. The same key serves those aggregates — computed daily from observed buy-box data, never estimated, with data_source on every answer.
- Brand dossier —
GET /v1/brand: how many sellers win the buy box on a brand, Amazon’s own share, FBA penetration, seller concentration and churn, trend grades, benchmarks against its category, the top sellers; monthly history on request. - Seller map —
GET /v1/brand/network: the brands connected to a brand because the same third-party sellers win the buy box on both — weighted edges and node metrics, one hop per call. See it drawn live on the homepage → - Operator footprint & category landscape —
GET /v1/seller/brands,/v1/seller/network,/v1/category: every brand a seller was observed winning on, the sellers that win beside it, and a category’s size, Amazon share, FBA share and concentration — plus ranked lists of brands, sellers and categories.
1 credit per record, 1 per page of 25 rows, lookups and misses free; part of every paid plan. Endpoint reference →
ASIN Data API answers per request type — product, search, offers, reviews, seller profile — one Amazon page per call. Nothing is aggregated across products, sellers or months.

Webotee AI Connect puts this same Amazon data to work inside Claude & ChatGPT — product search and shopping lookups like this API’s, plus a wide set of Amazon market stats and research tools: brand intelligence, seller networks, niche & category discovery, and AI-assisted evaluations grounded in observed data. Built by the team behind Logimu; plans from $19/month.
Run us side by side with ASIN Data API.
Start on the $19 Solo plan (14-day money-back), point your existing integration at both, and compare the latency, the data, and the bill. We are confident about all three.
