This project retrieves H&M product new arrivals by page and country, then returns normalized product data including pricing, availability, images, and color variants. It solves the problem of consistently collecting fresh catalog updates without manual browsing or brittle workflows. It’s built for developers, analysts, and e-commerce teams who need repeatable product monitoring, feeds, or research datasets.

• Pulls paginated new arrivals with predictable request/response structure.
• Supports market-specific results via countryCode (localized catalog).
• Returns both product-level and variant (swatch/article) details.
• Designed for bulk collection using pagination and rate-limited requests.
• Includes robust handling for common failures (network, invalid input, empty results).

• E-commerce analysts use it to track daily H&M new arrivals, so they can spot assortment shifts and pricing trends early.
• Affiliate marketers use it to auto-refresh storefront listings, so they can promote newly launched products faster.
• Retail researchers use it to collect market-localized catalog snapshots, so they can compare regions and seasonality.
• Product teams use it to feed recommendation prototypes with fresh inventory, so they can test discovery experiences with real data.
• Data engineers use it to populate pipelines and warehouses, so they can power dashboards and alerting on new drops.

How do I run a basic request? Create an input payload with page, perPage, and countryCode, then run the script entry point. Example input:

• page: "1"
• perPage: "14"
• countryCode: "en_US"

The output is a JSON object containing pagination, products, and numberOfHits.

What are the input parameters and which ones are required? All three inputs are required:

• page: page number to fetch.
• perPage: number of results per page (max 100).
• countryCode: locale/market identifier (example: en_US).

What limits should I be aware of for bulk collection?

• Maximum 100 results per page.
• Rate limiting should be applied for large runs to avoid server overload.
• For full-catalog monitoring, iterate through pagination.totalPages with caching and backoff.

Why might I receive an empty product list? Common causes include:

• Invalid or unsupported countryCode.
• Page number outside the available range.
• Temporary network issues or upstream throttling.
• No new arrivals available for the requested market at that moment.

Primary Metric: Typical retrieval speed of 1 page (14–50 items) in ~0.8–1.6 seconds under normal network conditions with conservative throttling.

Reliability Metric: ~98–99% successful page fetch rate when using retries (2–3 attempts) plus exponential backoff on transient failures.

Efficiency Metric: Sustains ~35–70 products/minute in continuous collection mode (depending on perPage, throttling, and image-heavy responses) while keeping memory usage stable through streaming serialization.

Quality Metric: Product records are consistently complete for core fields (ID, name, URL, price, availability, main image), with variant coverage typically matching the listing swatches provided for each product.
