JIAOZI invents no private standards — credentials are issued to the public standards below, independently verifiable with anyone's standard tools.
These are the public standards we follow or adapt to. Listing indicates technical alignment only — not an endorsement by any standards body.
Preview the same credential ID / DID through W3C DID, did:key and other adapter views — register once, interoperate everywhere.
None of the items below go through JIAOZI or need an account — anyone can check them, any time.
The China-site operator (Qinhuangdao QIJI Technology Co., Ltd.) is listed in China's national enterprise credit registry; the ICP filing number in the footer can be checked against the MIIT filing system — same legal entity.
The public keys used to check our signatures are free to fetch: the status-signing key at /api/status-key, and the issuer identity document at /.well-known/did.json on jiaozi.io. With those, anyone's standard tools can verify our credentials.
Credential JIAOZI-2026-000027 is public long-term. Verify it here on the spot, or with third-party tools — seeing is believing.
Which credentials are revoked is published at a fixed address using the W3C Bitstring Status List standard, re-signed every 60 seconds — history cannot be quietly rewritten.
The China and International portals verify the same global ledger, so results cross-check each other; issuance happens at the neutral Singapore node.
Our machine-readable self-descriptions live at /llms.txt and /.well-known/agent-card.json, saying the same things we tell humans — no double-speak.
