SQR can mint an ERC-721 NFT for any record, anchoring its provenance on-chain. Tokens are minted on Ethereum Sepolia (testnet).

​
Lifecycle

unclaimed → mint → minted → claim → claimed
  1. Create a record (status: unclaimed)
  2. Mint an NFT — the server wallet pays gas and receives the token
  3. Claim — transfer the NFT to an end-user’s wallet address

​
Mint a record

curl -X POST https://yys-sqr-render-bsbe.onrender.com/api/records/SQR-A1B2C/mint \
  -H "Authorization: Bearer $SQR_KEY"

{
  "success": true,
  "tx_hash": "0xabc123...",
  "token_id": 42,
  "etherscan_url": "https://sepolia.etherscan.io/tx/0xabc123...",
  "card": { "..." }
}
The record’s claim_status changes to minted.
Minting requires the server to have Web3 configured (ETH private key and contract address). If Web3 is not set up, you’ll get a 503 response.

​
Claim (transfer) the NFT

After minting, transfer the token to a wallet: 
curl -X POST https://yys-sqr-render-bsbe.onrender.com/api/records/SQR-A1B2C/claim \
  -H "Authorization: Bearer $SQR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"wallet_address": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD18"}'

{
  "success": true,
  "tx_hash": "0xdef456...",
  "etherscan_url": "https://sepolia.etherscan.io/tx/0xdef456...",
  "card": { "..." }
}
The record’s claim_status changes to claimed and claimed_by is set to the wallet address.

​
Via the dashboard

You can also mint and claim from the record detail page in the Dashboard. Click Mint NFT on any unclaimed record.

​
Viewing on Etherscan

After minting, the etherscan_url in the response links directly to the transaction on Sepolia Etherscan. You can verify the token ID, owner, and transaction details there.
