Also known as: open indexer
An indexer open to anyone who registers, usually with a free tier capped at a few dozen searches and downloads per day and a paid tier lifting those limits. Open sites carry heavy traffic, so coverage, speed and uptime vary considerably between them. Registration typically requires only an email address, and the account's API key authenticates any query made against it.
