Free. AuthiChain verification is free: use the verify_record tool, or GET https://authichain.com/api/verify. Paid plans are on hold, so no prices or Payment Links are listed.

Legacy x402 seal verify, not answering. Arguments that cannot be a seal UUID are HTTP 400 before payment. Empty arguments are unpaid HTTP 402 for discovery; a paid call is refused with 503 registry_not_bound before settlement, so no payment is taken. For free verification use verify_record.

Free public lookup for an assetId / seal / QR token. Never attests. Resolves the published packs (bat-2026-001, trumark, musa, strainchain); any other id returns status unknown, because the certificates registry does not answer yet. For free signature and anchor verification use verify_record.

Free. Verify an AuthiChain signed provenance record with the open reference verifier. Pass id "polygon-anchor-1" for the published demonstration record, or pass your own record and anchor JSON. Returns verified, valid-unanchored, or invalid, plus whether the transaction carries the record hash. It does not inspect a physical product.

Free EU Digital Product Passport readiness check. Returns a 0-100 score, gaps, and the dated obligation for the product category (battery passport is law from 18 Feb 2027; other categories are ESPR targets). Not legal advice.

Free. Scan a stored Living QR. GET https://authichain.com/qron/r/{object_id} returns AuthiChain Verification Decision v1. This host verifies the signature. A missing id is presentation_not_found. Not an x402 payment endpoint, and it does not inspect a physical product.
