One Request, Full Response

Amazon is a native integration within the kwery API. No separate implementation required.

Amazon data is available through the same kwery API endpoint as all other sources. Simply specify source: "amazon" in your request and kwery handles the rest, collection, validation, normalization. Same webhook delivery, same audit trails, same reliability guarantees.

Whether you're querying 1,000 products or 1 million, the same API serves your requests. Stream results as they complete. Process them asynchronously. No complex multi-source orchestration needed.

Buy Box winner and price, FBA vs. 3P merchant offers, Prime eligibility, seller identity, and stock status are the signals that drive most repricing decisions. kwery exposes all of them in a single normalized schema so your engine can weight them however your strategy requires, without parsing Amazon's product pages yourself.

The Buy Box winner can change multiple times per hour. kwery streams updates as they happen via webhooks, not batch polling. When a new seller wins the Buy Box, you get that signal immediately, so your repricing engine can react the same day instead of waiting for a nightly batch.

When Amazon updates its page structure, schema, or listing behavior, kwery absorbs the change centrally. Your integration keeps receiving results in the same schema with no code changes on your side. If a brief gap occurs, you're notified immediately and when service is restored.

Yes. The seller_type field indicates whether an offer is from Amazon (FBA), a Fulfilled by Amazon merchant (3P), or a traditional merchant seller. You can filter by seller type in your repricing logic or request only specific types in your queries.

Yes. The schema includes is_available status and shipping cost indicators. Prime eligibility is inferred from Amazon's fulfillment (FBA offers are Prime-eligible). See the full schema in the API Reference for complete availability indicators.

Data is always fresh. The moment kwery collects a new price from Amazon, it's delivered to you, either via webhook (if streaming) or available for polling. With high-volume jobs (10,000+ products), large collections take time, but each data point is current when delivered. You never get batched or cached results.
