How to read the answer

The agent reads items. catalog.stale means the price should be confirmed.

Groups

In stock is stock: in_stock. Stock not set in the feed is unknown: the stock field was empty, so stock is not promised. Out of stock is out_of_stock.

Freshness

catalog.stale: true appears when the last collection is older than CATALOG_MAX_AGE_HOURS (24 hours by default). The price should be confirmed.

The agent quotes price and stock after a successful call.
