## Data

- Freshness: live
- Keep data: no limit
- Use data: You agree not to use the Service, or data obtained through it, to: Harm or target individuals — stalking, harassment, doxxing, re-identification of anonymous users, or building profiles used to threaten, intimidate, or discriminate against people. Process personal data unlawfully — in violation of the GDPR, CCPA/CPRA, or other applicable data-protection laws, including using public personal data for a purpose the individual would not reasonably expect without a lawful basis. Enable unlawful discrimination — such as decisions about credit, employment, housing, or insurance based on protected characteristics. Infringe intellectual property — reproduce or redistribute content in violation of copyright, trademark, or database rights. Send spam or run deceptive campaigns — unsolicited bulk messaging, phishing, fraud, or impersonation. Circumvent controls — bypass authentication, rate limits, or access restrictions on any platform, or attempt to access non-public data. Break the law — any use that is illegal in your jurisdiction or that facilitates illegal activity. Resell or clone the Service — resell raw API access as a standalone substitute for Captapi or build a directly competing data API. [...] You must have a lawful basis for your processing, honor deletion and opt-out requests from data subjects, keep appropriate security, and comply with the terms of any platform you interact with.
