Subject: Feature Request: Introduction of a free API tier for all Proton servicesDear Proton Team,I am writing to you as a dedicated user and supporter of your platform. I deeply appreciate your ecosystem's commitment to digital privacy, security, and open-source software.I would like to formally suggest the introduction of a basic, free API access tier with reasonable rate limits across all of your services.Providing a foundational, free API would bring great value to both your team and the user base:Developer Innovation: It enables the community to build secure, open-source integrations and complementary tools.Ecosystem Growth: It will attract developers who will actively promote and build directly upon your privacy-first ecosystem.Secure Automation: Users could create local, secure backups and custom workflows without compromising their data privacy.To protect your infrastructure from abuse, this free tier could be strictly rate-limited with a low daily quota, which would naturally encourage premium upgrades for heavy or production use.Thank you for your time, consideration, and continuous hard work in defending global digital privacy.Sincerely,
