username.md

The product is a personal handle service that provides a single username page, email forwarding address, and verifiable API to consolidate scattered profiles and prove identity with cryptographically signed responses. It is for individual consumers, creators and gamers managing online presence, and developers and AI agents that need to look up and verify a person programmatically. It is delivered as a hosted SaaS with a free read API serving HTML, JSON and Markdown over HTTPS using open standards such as did:web and Ed25519 signatures.
