API: What Are Inferred documents And 5 Day Out Of Stock Methodology?

Some retailers remove products from their site once they sell out. When this happens, our system can no longer crawl the product page, so we infer that the product is out of stock.

To reduce the chance of errors, we use a methodology that checks whether the product returns to the site over a five-day period before confirming its status.

Read a thorough description of this methodology on the API documentation:
