The QR-V™ Verification API provides developers with programmatic access to the QR-V verification network, enabling applications to validate QR-bound artifacts, retrieve registry proofs, and confirm the integrity of digital or physical objects.

The API is designed to integrate easily into:

• mobile scanners
• web verification portals
• enterprise verification systems
• supply chain software
• identity and certificate platforms

---

1. Core API Capabilities

The QR-V API supports several primary operations.

Artifact Verification

Verify whether a QR-V code corresponds to a valid registry entry.

Registry Lookup

Retrieve artifact records from the verification registry.

Certificate Retrieval

Access the verification certificate associated with a QR-V artifact.

Audit History

Retrieve scan or verification events linked to an artifact.

---

2. API Base Endpoint

Example base endpoint:

https://qrv.network/api/v1

All requests are made over HTTPS to ensure secure communication.

---

3. Authentication

Developers obtain an API key from the QR-V developer portal.

Example request header:

Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

---

4. Verify a QR-V Code

Endpoint

POST /verify

Request

POST https://qrv.network/api/v1/verify

Body:

{
  "qr_payload": "QRV://v1/ODIN-12345/sha256/abc123..."
}

Response

{
  "status": "verified",
  "object_id": "ODIN-12345",
  "issuer": "QRV Registry Authority",
  "certificate_id": "CERT-98341",
  "timestamp": "2026-02-22T19:42:00Z",
  "integrity": "valid"
}

---

5. Lookup an Artifact

Endpoint

GET /objects/{object_id}

Example:

GET https://qrv.network/api/v1/objects/ODIN-12345

Response:

{
  "object_id": "ODIN-12345",
  "hash": "abc123...",
  "created": "2026-02-22",
  "issuer": "Registry Authority",
  "certificate_id": "CERT-98341"
}

---

6. Retrieve Certificate Data

Endpoint

GET /certificates/{certificate_id}

Example:

GET /certificates/CERT-98341

Response:

{
  "certificate_id": "CERT-98341",
  "object_id": "ODIN-12345",
  "issuer": "Verification Authority",
  "issued_at": "2026-02-22",
  "signature": "digital-signature-data"
}

---

7. Verification Flow

Typical QR-V verification flow:

User scans QR-V
       ↓
Client extracts QR payload
       ↓
Application calls QR-V API
       ↓
Registry lookup
       ↓
Proof validation
       ↓
Verification result returned

---

8. Example JavaScript Integration

async function verifyQR(payload) {

  const response = await fetch(
    "https://qrv.network/api/v1/verify",
    {
      method: "POST",
      headers: {
        "Authorization": "Bearer YOUR_API_KEY",
        "Content-Type": "application/json"
      },
      body: JSON.stringify({
        qr_payload: payload
      })
    }
  );

  const result = await response.json();
  console.log(result);

}

---

9. Typical Use Cases

The QR-V Verification API can be integrated into:

Identity Systems

• ID cards
• digital passports
• membership credentials

Certificates

• educational credentials
• licenses
• digital diplomas

Supply Chains

• product authenticity
• shipment tracking
• anti-counterfeit protection

Digital Assets

• ownership verification
• contract validation
• artifact registration

---

10. Developer Resources

Typical developer tools include:

• API documentation
• SDK libraries
• verification test sandbox
• payload generator tools
• registry explorer

Example developer portal structure:

/developers
/api-reference
/sdk
/sandbox
/examples
/status

---

11. Best Practices

When integrating the QR-V API:

✔ Validate payload format before API calls
✔ Cache registry results when appropriate
✔ Implement retry logic for network requests
✔ Verify certificates locally when possible
✔ Use rate limiting for high-volume scanning

---

12. Example Deployment Scenarios

Organizations can deploy QR-V verification in:

• airports and identity checkpoints
• supply chain verification systems
• certificate verification platforms
• event ticket validation systems
• digital asset authentication services
