Protocols like x402 let an agent pay for an API key or resources with no human in the loop. It's clever for metered SaaS. Hushdrop doesn't need it: self-host runs on your own infra for free, and the managed tier is anonymous.
Free beats metered here
There's nothing for an agent to buy — your agents publish with your own token (self-host) or anonymously (managed). See Hushdrop and x402.
FAQ
Is it really open-source and self-hosted?
Yes — MIT licensed, and it runs on your own Vercel Blob + domain. No third party ever holds your content (it's encrypted client-side) or controls your URL.
