Captureapp

Capture is presented as the first blockchain licensing framework with x402 support, combining embedded C2PA content credentials, ERC-7053 on-chain registration, and HTTP-native micropayments so creators can prove provenance, comply with EU AI Act Article 50, and earn USDC when AI agents fetch assets. The stack anchors tamper-evident receipts to the Numbers Mainnet and exposes each registered asset as a paid licensing endpoint, enabling AI agents to pay per fetch and receive an on-chain consent receipt in one round-trip. Capture provides SDKs for iOS, Android, and Node.js, an ISO 27001-certified C2PA signing API, decentralized storage via IPFS and the Numbers Mainnet, and companion apps (ProofSnap for iOS, Capture Cam for Android) and tools (Capture Eye, Capture Dashboard) to integrate provenance and monetization into publisher and creator workflows.

Key Features

C2PA content credentials

Embed cryptographic provenance (creator identity, timestamp, geolocation, edit history) directly into every photo or video at capture time using C2PA content credentials.

ERC-7053 on-chain registration

Register assets on-chain with ERC-7053 to anchor a tamper-evident receipt on the Numbers Mainnet so ownership and timeline remain provable even if metadata is stripped.

x402 HTTP-native micropayments

Expose each registered asset as an x402-paid HTTP licensing endpoint: AI agents call the URL, pay USDC, and receive an on-chain consent receipt in one round-trip.

SDKs and integrations

SDKs for iOS, Android, and Node.js that plug into existing CMSs, DAMs, and AI pipelines for easy integration.

ISO 27001-certified C2PA signing API

An ISO 27001-certified signing API intended for high-volume publishers to sign content at scale.

Decentralized storage & anchoring

Assets are anchored on the Numbers Mainnet with IPFS storage for immutable, tamper-evident preservation.

Programmable licensing and pricing

Define how assets can be used and set per-fetch pricing; AI agents query x402 endpoints and pay per fetch (example fetch pricing provided on the site).

Companion apps and tools

ProofSnap (free iOS app) and Capture Cam (Android) for capture-time signing; Capture Eye for embedding a provenance widget; Capture Dashboard for provenance creation.

Pricing

Free Tier Available

Capture Dashboard is described as a free-to-use online tool; ProofSnap iOS app is described as free.

Per-fetch licensing

AI agents pay per fetch; example site range $0.01–$1.00 USDC per fetch (site-provided range).
  • HTTP-native x402 micropayments
  • On-chain consent receipt in one round-trip

Use Cases

AI licensing & consent for training data

Expose assets as paid licensing endpoints so AI agents must request and pay for access, producing on-chain consent receipts for compliance and monetization.

Media and newsroom provenance

Provide tamper-evident provenance for journalistic content, helping newsrooms comply with provenance requirements and maintain content integrity.

Creativity and copyright protection

Allow artists and creators to embed provenance and register ownership on-chain to protect, track, and monetize creative works.

Digital archive preservation

Anchor assets to the blockchain with decentralized storage to create tamper-evident, long-term preservation that survives metadata stripping.

Product authenticity & ESG reporting

Enable digital product passports, lifecycle tracking, and verifiable sustainability reporting with provenance and on-chain records.

Integrations

x402 (micropayments)

Enables HTTP-native micropayments so AI agents pay USDC when fetching assets and receive on-chain receipts.

C2PA

Embeds content credentials (provenance metadata) directly into assets at capture time.

ERC-7053 / Numbers Mainnet

On-chain registration and anchoring of tamper-evident receipts to the Numbers Mainnet.

IPFS (decentralized storage)

Preserves registered assets in decentralized storage to survive metadata stripping and provide long-term preservation.

SDKs (iOS, Android, Node.js)

Client libraries to integrate Capture into mobile apps, CMSs, DAMs, and AI pipelines.

Benefits

Compliance with EU AI Act Article 50 through multi-layered provenance (embedded C2PA + on-chain registration).
Monetization via HTTP-native x402 micropayments: creators can earn USDC each time an AI agent fetches their asset.
Tamper-evident provenance and long-term preservation via ERC-7053 anchoring to the Numbers Mainnet and IPFS storage.

Frequently Asked Questions

What is Capture?
Capture is the first blockchain licensing framework with x402 support, combining C2PA content credentials, ERC-7053 on-chain registration, and HTTP-native AI-agent micropayments in a single open stack to protect work, comply with provenance regulations, and monetize when AI agents fetch assets.
How does Capture help comply with EU AI Act Article 50?
Capture combines two layers — embedded C2PA credentials inside the file plus ERC-7053 on-chain registration — addressing the draft Code of Practice's multi-layered approach requirement for provenance and machine-readable marking.
What is x402 and how does Capture support it?
x402 is an HTTP-native micropayment protocol stewarded by the x402 Foundation; Capture exposes each signed and registered asset as an x402-paid licensing endpoint so AI agents call the URL, pay USDC, and receive an on-chain consent receipt in one round-trip.
What makes ProofSnap unique?
ProofSnap is a free iOS camera app that seals every photo and video with C2PA Content Credentials and an ERC-7053 on-chain receipt at capture time, designed for journalists and frontline storytellers with a minimal UI and no crypto skills required.
