TAG IT Verify

TAG IT Verify gives AI agents trusted access to the physical world. It is live on OKX.AI as an Agentic Service Provider: Agent ID 6265 on X Layer.

THE PROBLEM

AI agents can already discover products, negotiate, swap, pay and settle on-chain. But they cannot determine whether the physical product behind a transaction is genuine, stolen, recalled or unknown.

Before an agent releases payment, it needs evidence—not another promise.

WHAT TAG IT VERIFY DOES

With one free A2MCP call, an agent can check:

• Authenticity
• Lifecycle state
• Flagged or risk status
• Custody summary
• On-chain contract and token reference

The agent submits an asset tag ID from a secure NXP NTAG 424 DNA chip bound to the product. TAG IT Verify returns a structured verdict the agent can understand and act on.

Every response includes a chainRef pointing to the contract and token ID on Base Sepolia, allowing independent on-chain verification.

The service is read-only, rate-limited and returns zero personal information.

TRY IT

POST https://api.tagit.network/asp/verify

Clean asset:
{"tagId":"DEMO-AUTHENTIC"}

Flagged asset:
{"tagId":"DEMO-FLAGGED"}

Unknown asset:
{"tagId":"DEMO-UNKNOWN"}

DEMO-AUTHENTIC returns a clean verdict backed by an on-chain digital twin. DEMO-FLAGGED warns the agent not to transact. DEMO-UNKNOWN honestly reports that the asset is not registered.

HOW IT WORKS

A secure NFC chip is cryptographically bound to an ERC-721 digital twin managed by TAGITCore.

TAGITCore tracks the complete physical-asset lifecycle:

NONE → MINTED → BOUND → ACTIVATED → CLAIMED → FLAGGED → RECYCLED

When an agent calls TAG IT Verify, the service reads the asset’s verification and blockchain state, then returns a clear decision:

PROCEED · STOP · UNKNOWN

WHY IT MATTERS FOR OKX.AI

The future of agentic commerce includes real products—not only digital assets.

Marketplace agents, procurement systems, resale platforms, insurers and financing agents all need trusted physical-world information before taking action.

TAG IT Verify is the trust call before the transaction.

Built by TAG IT Network—cryptographic digital twins for physical assets.

Built during the hackathon window (July 15–17, 2026):

1. A2MCP verify endpoint (POST/GET /asp/verify) wrapping our existing verification stack — free tier, rate-limited, read-only, zero PII. 15 new unit tests; full suite 417/417 green. Deployed to production at api.tagit.network.

2. Live demo assets seeded on Base Sepolia: DEMO-AUTHENTIC is a real ERC-721 (token #50) walked through the full lifecycle mint, bind, activate, claim — its verdict links straight to Basescan. DEMO-FLAGGED demonstrates the stolen-asset abort path. DEMO-UNKNOWN returns an honest not-found.

3. Registered an ERC-8004 agent identity on X Layer via OKX OnchainOS (Agent ID 6265, gas sponsored by OKX) and listed TAG IT Verify on OKX.AI as a free A2MCP service — passed listing validation with zero findings.

4. Every verdict now carries a chainRef (contract + token ID + explorer link) so judges and agents can independently re-verify on-chain.

5. Pre-existing foundation reused: TAGITCore contracts (7-state lifecycle), NTAG 424 DNA hardware integration, and the tagit-services backend.

TAG IT Network has been self-funded to date and has not raised institutional capital. We are currently raising in pre-seed financing through a SAFE (Simple Agreement for Future Equity) to accelerate product development, security and production hardening, NFC hardware integration, enterprise pilots, and go-to-market execution. SAFE valuation cap and discount terms are open for discussion with qualified investors.
