Prove origin with C2PA + ERC-7053
Every piece of content gets a verifiable identity: who created it, when, where, and how it was edited. C2PA embeds provenance metadata. ERC-7053 indexes it on-chain.
Capture by Numbers Protocol
The Licensing Infrastructure for the Machine Economy
The first and only blockchain licensing framework with x402 support. Prove origin with C2PA. Index on-chain with ERC-7053. Get paid automatically, even when your reader is an AI agent.

Capture
From Defense to Terms
The old approach was blocking AI scrapers. The new approach is setting terms at the infrastructure level. Capture combines C2PA content credentials, ERC-7053 blockchain indexing, and x402 payment rails into a single stack so your content is authenticated, discoverable, and payable by machines.
Prove, License, Earn
Capture turns verified human content into a machine-readable licensing asset.
Set machine-readable terms via x402
x402 adds payment requirements to HTTP. When an AI agent encounters your content, it can read the licensing terms and pay automatically.
Get paid with receipt NFT audit trails
Every licensing transaction can generate USDC payment and an indexed receipt NFT, creating auditable evidence for compliance and dispute resolution.
How Capture Works
Create & Sign
Use ProofSnap or the C2PA Signing API to embed content credentials at the point of creation or publication.
Index On-Chain
ERC-7053 indexes your content's provenance history on Numbers Mainnet so it is discoverable by AI agents and verifiable by anyone.
Set Licensing Terms
Define per-asset pricing and usage rights through Capture Dashboard or your own white-label marketplace.
AI Agent Pays via x402
When an AI agent discovers your content, it reads the x402 payment header, licenses the content automatically, and receives auditable proof of payment.
