## Changelog

### 0.1.0 — 2026-05-22

Initial release. Pay-per-event Walmart search results scraper:

- Input: `searchQueries`, `maxProductsPerSearch`, `maxSearchPages`, `sort`, `maxRequestRetries`, `proxyConfiguration`.
- Output: `usItemId`, `name`, `price`, `priceString`, `wasPrice`, `wasPriceValue`, `savings`, `onSale`, `discountPercent`, `rating`, `reviewCount`, `seller`, `fulfillmentType`, `flag`, `thumbnail`, `url`, `isSponsored`, `brand`, `currency`, `pageNumber`, `searchQuery`, `scrapedAt`.
- Run-scoped deduplication by `usItemId` so duplicate items across overlapping keyword searches and sponsored-then-organic placements are billed at most once.
- Charges `product_scraped` ($0.0046 list, $2.40/1k on Business Gold's 48% subscription-tier discount) only after `pushData` succeeds.
- Residential proxy default; HttpCrawler with low concurrency (5) and session pool to ride Walmart's bot detection.
- `Actor.on('aborting')` flushes state and exits within 1s so user cost ceilings are honored.
