Capture products
One stack. Seven surfaces.
Pick the entry point that fits your workflow. Every product implements the same C2PA + ERC-7053 + x402 stack, so you can mix, match, and migrate freely.

x402 Licensing
Wrap C2PA-signed, ERC-7053-registered assets in HTTP-native licensing endpoints. AI agents call the URL, pay USDC micropayments, and receive on-chain consent receipts — provenance, payment, and audit in one round-trip.
