How it works

Four steps to sovereign reviews

Export
Google Takeout. Your data, your legal right under GDPR and data portability law.
Sign
Ed25519 + JWT-VC. Cryptographic proof of authorship bound to your DID.
Host
Your domain, your server. Each author node is an independent x402 endpoint.
Get Paid
x402 micropayments. AI agents pay USDC per request. No intermediary.

For AI companies

Rights-clean data.
Zero friction.

Every review is cryptographically signed, verifiably authored, and licensed at the protocol level. Your agents handle payment automatically.

  • Cryptographically signed
    Ed25519 signatures + JWT-VC. Every review traceable to its author's DID.
  • x402 native
    HTTP 402 → auto-pay → content. No API keys, no rate limits, no accounts.
  • Verifiable provenance
    Content hash + did:web. Trace any review to its Google Takeout origin.

For reviewers

Get paid for what you already wrote.

Your reviews are valuable training data. AI companies know it. Now you set the price.

  • Export from Google Takeout
    Your legal right under GDPR and data portability regulations. One download.
  • One command to sign everything
    4me2 import handles parsing, signing, and verification. Seconds, not hours.
  • Host on your domain
    Self-host or use a managed node (coming soon). Your server, your rules.
  • Passive income
    AI agents pay every time they access a review. Micropayments accumulate.
Managed nodes

Skip the server setup.

Running your own node today means a domain, a deployed server, and a wallet. We're building a managed version where you upload your Takeout export and get a signed, payable endpoint. Leave your email and we'll tell you the moment it opens.

No spam. One email when managed nodes open.

Open source

Apache 2.0.
Build with us.

4me2 is open source from day one. Same license as x402. Maximum adoption, patent protection included.
