The Open Page Rank API gives a 0 to 10 authority score and global rank for domains, based on Common Crawl link data, with a monthly history. Use it to compare sites, sort link lists or watch a domain's ranking. Send up to 100 domains per POST request and get JSON back, with the key in the Authorization header. Free with a free API key that works from one IP address; paid plans remove that limit.
