Easy integration
SDKs for iOS, Android, and Node.js plug into existing CMSs, DAMs, and AI pipelines. ISO 27001-certified C2PA signing API for high-volume publishers.
Provenance and payment, in one open stack
Prove your content. Get paid by AI.
Capture pairs C2PA content credentials and ERC-7053 on-chain registration with x402 HTTP-native micropayments — so creators stay compliant with EU AI Act Article 50 and earn USDC every time an AI agent fetches their work.

How it works
From capture to payment in one open stack
Sign with C2PA
Embed cryptographic provenance — creator identity, timestamp, geolocation, edit history — directly in every photo or video at capture time.
Register on-chain
ERC-7053 anchors a tamper-evident receipt to the Numbers Mainnet. Even if metadata is stripped, ownership and timeline remain provable.
Earn via x402
Each registered asset becomes an HTTP-native licensing endpoint. AI agents call the URL, pay USDC, and get an on-chain consent receipt in one round-trip.
Why Capture
The only solution that covers all three layers
| Capability | Capture | Adobe CAI | Truepic | Digimarc |
|---|---|---|---|---|
| C2PA content credentials | Yes | Yes | Yes | Watermark only |
| On-chain registration (ERC-7053) | Yes | No | No | No |
| x402 AI-agent micropayments | Yes | No | No | No |
| EU AI Act Article 50 multi-layer | Yes | Single layer | Single layer | Single layer |
| Open standard governance | Yes | Yes | Proprietary | Proprietary |
What you get
Retain control. Earn revenue.
Decentralized storage
Every asset is anchored on the Numbers Mainnet with IPFS storage — secure, immutable, and long-lasting preservation that survives metadata stripping.
Programmable licensing
Define how your assets can be used. AI agents query x402 endpoints, pay $0.01-$1.00 USDC per fetch, and receive on-chain consent receipts.

Frequently asked questions
The basics, answered.
What is Capture?
Capture is the first blockchain licensing framework with x402 support. It combines C2PA Content Credentials, ERC-7053 on-chain registration, and HTTP-native AI-agent micropayments in a single open stack — letting creators protect their work, comply with content provenance regulations, and monetize automatically when AI agents fetch their assets.
How does Capture help comply with EU AI Act Article 50?
EU AI Act Article 50 (enforced August 2 2026) requires AI-generated content to be marked in machine-readable form. Capture combines two layers — embedded C2PA credentials inside the file, plus ERC-7053 on-chain registration — directly addressing the draft Code of Practice's "multi-layered approach" requirement. Non-compliance carries fines up to €15M or 3% of global revenue.
What is x402 and how does Capture support it?
x402 is the HTTP-native micropayment protocol stewarded by the x402 Foundation (Coinbase + Cloudflare). Capture is the first and only blockchain licensing framework with x402 — every signed and registered asset is exposed as a paid licensing endpoint that AI agents call directly, paying USDC and receiving an on-chain consent receipt in one round-trip.
What makes ProofSnap unique?
ProofSnap is a free iOS camera app from Numbers Protocol that seals every photo and video with C2PA Content Credentials and an ERC-7053 on-chain receipt the moment you press the shutter. It is purpose-built for journalists and frontline storytellers — minimal UI, no crypto skills required. Android creators can use the Web3-native sibling app, Capture Cam, for the same dual-standard signing plus NFT minting and multi-chain support.
