Blockchain Certificate API
For High-Volume Manufacturers
Integrate blockchain-powered product authentication into your supply chain. Create immutable certificates for every unit, protect high-volume lines with scalable API infrastructure, and give each product a unique on-chain identity that cannot be replicated or altered.
Blockchain-Powered Security
Immutable product records on Polygon
Real-Time Verification
Supply-chain and point-of-sale authenticity checks
Global Scalability
Built for manufacturing and distribution at scale
Developer-Friendly

"quantity": 10,
"metadata": {
"name": "Product name",
"serial_number": "SN-1001"
}
}Each pool item includes a qrCode URL to print on the product.
The buyer scans the QR, enters the serial number, and uploads proof of purchase.
When approved, the existing on-chain certificate is linked to their account — no second mint.
How It Works
From factory floor to customer wallet — a five-step integration path for manufacturers, distributors, and retailers using the Ownership Tag API.
Security & Fraud Prevention
Claim review, not auto-assign
Every claim requires matching serial number and proof of purchase. Duplicate QR scans create separate pending requests — only the legitimate buyer is approved.
Blockchain immutability
Product metadata on Polygon cannot be altered after mint. Transfers are permanently auditable.
API key security
Hashed keys, role-based access, and full audit logging for compliance.
Webhook notifications
Real-time alerts on claims, transfers, and verifications for fraud detection in your systems.
Typical timeline: integration in days, not months — start with a small pre-mint batch and scale volume as you go.

Pay only for blockchain certificates created. Credits are consumed per certificate created (see Purchase Credits in the dashboard). Per-certificate rates depend on how many credits you buy in one purchase. See the tiers above.
Typical manufacturer flow
- Register at developer signup and pass admin approval.
- Purchase credits in the developer dashboard (60-day expiry; optional auto-charge).
- Create API keys, then call POST /api/v1/unclaimed to pre-mint and print QR codes.
- Customers use Claim Ownership; your team or Ownership Tag admins approve claims.
What's included:
- Blockchain certificate creation and permanent storage on a secure blockchain network
- Unlimited API calls (read-only operations are free)
