A tool for human creators to register and protect what they brought into existence. Your file is never uploaded, watermarked, or altered. Our process is zero-knowledge by design, only your file's cryptographic fingerprint ever reaches spArxx.io. What comes back is a timestamp: your independently verifiable record of having registered it first. The contents of your files remain private to you.

Built on MCP (the same open standard Claude uses for secure, authenticated tool access), the spArxx.io connector lets your AI register timestamps, check your balance, retrieve receipts, and verify blockchain anchors ... all mid-conversation, no app-switching. Every timestamp anchors to the Polygon blockchain, independently verifiable forever after ... no trust in spArxx.io required beyond the public chain itself.

spArxx.io is built for human creators, and that shows up in how it's provisioned, not just in its purpose: connecting gets your AI access to the tools, but a human still provisions the account behind the connection. This is deliberate, since this registration only means something with a human behind it.

Priced to use: agentic timestamps run at 20 spArks (~$0.20) ... the lowest rate on the platform.
