How does x420 get cheaper GPT-5.5 tokens?
X420 buys unused AI capacity from verified partners. That capacity is pooled behind our OpenAI-compatible proxy, metered per request, then sold as credit with savings up to -50%.
Privacy
Zero-trust architecture, isolated secrets, minimized content.
Our architecture follows zero-trust and least-privilege principles: traffic uses TLS 1.3, upstream secrets stay isolated server-side, customer keys are tenant-separated, hashed, rotated, and never exposed to the frontend. Payloads are not used for training, are not resold, and X420 applies data minimization: the proxy routes the request, bills usage, then avoids retaining raw content.
