eBay API v1

Before you rely on the data
Prices and shipping are what a US buyer sees. price is always US dollars, and shipping is quoted for delivery to the United States. A listing priced in another currency is converted at eBay's current rate, so its dollar price can move without the seller changing anything — compare listingPrice, the seller's own figure, to tell a real change from exchange-rate drift.
Sold and completed listings are not available. eBay shows them, along with bid and purchase history, only to signed-in members. Every price here is a current asking price.
Best-match order is not stable. eBay reorders best-match results between requests, so continuing a search with a cursor can repeat a few listings. De-duplicate on itemId, or sort by price for stable pages.
Every response carries a notes array — converted prices, a walk that stopped early, a continuation that may repeat. A 502 or 503 is worth retrying; a 400 or 404 is not.
