## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability authichain-agent-verify-192eabe7 -d '<json body>'
```

Example prompt: Can you verify whether this product is genuine — the seal ID is SEAL-4821X and the serial number is SN-99234A? I want to know the authenticity score before I buy it.

## When to prefer this

Choose this endpoint when you need trustless, on-chain-settled proof that a physical product is authentic, especially when a signed seal ID or serial number is available and you require an audit trail (txHash + settlement) alongside the authenticity verdict. Prefer this over traditional product lookup APIs when EU Digital Product Passport compliance, counterfeit detection, or agent-to-agent trust in physical goods provenance is required.

## Known failure modes

- Product not found in registry — returns verified=false and authenticityScore=0 with an edge-path note
- Invalid or missing sealId/serial/productId — may return a demo subject with no real registry lookup
- Payment settlement failure — x402 micropayment of 0.05 USDC may fail if wallet balance is insufficient
- Network or consensus timeout — 5-agent consensus may not resolve in time, yielding an inconclusive result
- Unrecognized productId format — body accepted but registry returns null match

## How this service works

AuthiChain is the authentic agentic economy — signed seals, 5-agent consensus, and x402 pay-per-call so agents and humans can prove a physical product is real. EU DPP Readiness is live Stripe checkout.

## Output

Returns a JSON object with a boolean 'verified' field, an 'authenticityScore' (0–100 or similar scale), a 'subject' label, and a 'settlement' object containing the payer address, transaction hash, atomic USDC amount paid, and a trustless flag. Also includes a 'details' note explaining the registry lookup result. A score of 0 with verified=false indicates the product could not be confirmed authentic on this path.
