| Tool | Description | Behaviour |
|---|---|---|
| dpp_readiness_check | 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. | Not declared |
| get_pricing | 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. | Not declared |
| query_provenance | Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. For free signature and anchor verification use verify_record. | Not declared |
| verify | Legacy x402 seal verify, not answering. Unpaid tools/call returns 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. | Not declared |
| verify_record | Free. Verify an AuthiChain signed provenance record with the open reference verifier, then read its Polygon anchor transaction. Pass id "polygon-anchor-1" for the published demonstration record, anchored on Polygon mainnet in tx 0x2491…10b7, 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. | Not declared |
