Your NFT can earn
when AI uses it.

Voxel Vault turns eligible VoxelFlip NFTs into paid machine-use assets. AI agents and apps discover the catalog, pay a small Base USDC fee through x402, and receive a one-use license receipt.

Receiver + facilitator are configured for Base.

10000 atomic USDC · Base mainnet · one machine-use unit.

Open /pay for a direct Base USDC test payment prompt.

Only assets still owned by the configured licensor wallet are offered.

Every x402 paid request returns a machine-readable one-use license receipt and payment proof.

Agents read the catalog

The free JSON catalog exposes eligible assets and the paid endpoint, so builders can integrate without asking for access first.

x402 handles Base USDC

The paid endpoint returns an HTTP 402 challenge. A compatible agent pays, then the app verifies and settles the payment.

One use, one receipt

After payment, the app returns a receipt for one machine-use unit. Additional uses require additional payments.

Test the paid endpoint in minutes.

POST a token ID to /api/licenses/use. Without a payment, the endpoint returns the standard x402 HTTP 402 challenge. After verification + settlement, it returns the machine-use license plus the Base payment transaction proof.
