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 indicating overall authenticity pass/fail, an 'authenticityScore' (numeric, 0–100 or 0–1 scale), a 'subject' label, 'details' with narrative notes, and a 'settlement' object containing the payer address, transaction hash, amount in atomic units, and trustless flag for the x402 payment record.
Example use cases
Pre-purchase counterfeit check
“Before I buy this luxury handbag, can you check if it's authentic using AuthiChain? The seal ID printed on the tag is SEAL-LV9023 and the serial is SN-88412001.”
EU Digital Product Passport compliance
“We need to verify this electronics component meets EU DPP requirements — can you run an AuthiChain authenticity check on product ID PROD-EU-4471 with serial number SN-20230915?”
Resale marketplace fraud prevention
“A seller is listing a watch with seal ID SEAL-RX2024 and serial SN-99001234 — can you verify whether that product checks out as legitimate before we allow the listing?”
Technical details
Endpoint
POSThttps://authichain.com/api/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cryptographically attest that a physical product is genuine, especially when on-chain settlement proof and an authenticity score are required. Ideal for anti-counterfeiting workflows, EU Digital Product Passport compliance, resale marketplace verification, or any agent pipeline that must prove product provenance to a human or another system. Prefer this over generic QR/barcode lookup services when trustless blockchain settlement and multi-agent consensus attestation are required.
Side effects
- Registry lookup not bound on edge path — returns verified:false with authenticityScore:0 and a note in details
- Invalid or missing sealId/serial/productId — request may return unverified result with no registry match
- Payment settlement failure — x402 micropayment not confirmed, call rejected
- Network or consensus timeout — 5-agent consensus may not resolve in time, returning indeterminate result
- Malformed body type — bodyType must be one of json, form-data, or text; mismatches cause schema rejection
