Register Information via API in SmartCheck
Generate digital proofs from any system without accessing the platform.
SmartCheck is a Code Contract feature that allows you to generate unique, secure, and immutable digital evidence in seconds and at an affordable cost.

Below, we detail how you can perform these registrations:

Step 1: Obtain the Authentication Token

First, you must authenticate with the SmartCheck API by sending a POST request to obtain a JWT token. This token will be used in subsequent requests.

Authentication Request (HTTP Request)

POST /login HTTP/1.1  
Host: api.codecontract.io  
Content-Type: application/json  

{  
    "email": "your_email_address",  
    "password": "your_password"  
}

Expected Response

HTTP/1.1 200 OK  
Content-Type: application/json  

{  
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9..."  
}

The token value must be stored and included in every subsequent request as a Bearer Token in the Authorization header.

Step 2: Certify Data with SmartCheck

Once authenticated, you can certify data using the corresponding endpoint.

Request to Create and Register Merkle Root
This endpoint allows you to create a Merkle tree with your data and register its root on the blockchain.

POST /smartcheck/createTreeAndRegisterMerkleRoot HTTP/1.1  
Host: api.codecontract.io  
Content-Type: application/json  
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...  

{  
    "data": [  
        "data1",  
        "data2",  
        "data3"  
    ]  
}

Expected Response

{  
    "merkleRoot": "abc123...",  
    "transactionId": "tx123...",  
    "status": "success"  
}

This response includes the generated Merkle root, the blockchain transaction ID, and the operation status.

Step 3: Retrieve Proof Details

To verify or retrieve the details of a certification, use the following endpoint and provide the corresponding identifier.

Request to Retrieve Proof Details

GET /smartcheck/reportsProofDetail?reportId=your_report_id HTTP/1.1  
Host: api.codecontract.io  
Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...

Expected Response

{  
    "reportId": "your_report_id",  
    "merkleRoot": "abc123...",  
    "data": [  
        "data1",  
        "data2",  
        "data3"  
    ],  
    "status": "verified"  
}

This response provides details about the certification, including the Merkle root, the certified data, and the verification status.

Summary

✔️ Step 1: Obtain the JWT token via authentication.
✔️ Step 2: Certify your data by creating and registering the Merkle root on the blockchain.
✔️ Step 3: Retrieve certification details as needed.

Remember: all API requests must include the JWT token in the Authorization header using the format: Bearer {token}.
