| Use data | You may use the API and the results it returns in your own products and processes, but you may not copy, resell or provide the Service itself to others, or use it to build a competing service. [...] You must have a lawful basis, under data protection and electronic marketing law, to collect and process every email address you submit. [...] You must not: send spam or unsolicited bulk email, or help anyone else do so, including by cleaning lists for that purpose, validate addresses that were scraped, harvested, guessed, generated or bought without the people's consent, use the Service to find, track, harass or impersonate anyone, or to check whether a particular person has an account somewhere, use the Service for fraud, phishing, malware or any other unlawful or harmful purpose, create multiple free accounts, or share or resell API keys, to get more lookups than your plan allows, get around rate limits, quotas, bot checks or other limits, or send traffic designed to overload the Service, probe, scan or test the security of the Service, except as allowed by our security policy, reverse engineer the Service, or copy our data, such as typo or disposable-domain lists, to build a competing product, resell or provide the Service itself to others without our written agreement |
