Verify any AI agent identity in one click.
Protect every transaction you make.
Enter an AI agent’s DID or JIAOZI credential ID — the Verifier tells you on the spot who holds the credential and whether it is trustworthy right now.
Built on W3C open standards — it can verify any AI agent identity that conforms to those standards.

Take the verifier with you
The verifier is free, lightweight and yours to take: embed it in your page, import it in your code, or pin a badge. Every embed lets your visitors verify agents on the spot.
Import in your code
SDKs (JS / Python) let your system verify every visiting agent automatically; REST API and CLI included. npm / PyPI release in preparation.

An SVG badge that reflects live credential status — green means alive, red means revoked, and no one can fake it.

Why AI needs verifiable identity Read the explainer →
Agents now place orders, sign deals and call each other on our behalf. Whose agent is this? What is it authorized to do? Is it still trustworthy right now? Without verifiable identity, all three are guesswork — and when something goes wrong, no one is accountable. Verifiable identity gives strange agents a basis to shake hands for the first time.
What can it verify?
Not just JIAOZI credentials. The verifier is built on W3C DID/VC open standards: any did:web identity gets a standards-conformance check, and any standards-based credential can be signature-verified. JIAOZI-issued credentials additionally carry live status, trust tiers and an accountable issuance chain — and you're never locked in.
Try it yourself: paste any did:web in the box above — including ones we didn't issue.
One credential answers four questions
Who is it?
Which verified party authorized it, with an auditable chain of accountability. The DID is permanent and rotatable; keys are generated locally — we never hold them.
What may it do?
Permissions only narrow, never widen, down the delegation chain; sub-agents inherit within their parent's bounds.
Trusted right now?
Status is re-signed every 60 seconds; revocation and locking are immediately visible — you verify the present, not the past.
Is the code trusted?
Optionally bound to code metrics and TEE attestation; attestation runs on your machine — source code and private data never leave it.
Why trust JIAOZI?
Backed by open standards
Built on W3C DID/VC, A2A and IETF Web Bot Auth, with SM2/SM3 support — no proprietary standards invented here.
Independently verifiable
Credentials verify with standard third-party tooling — even if this site goes offline. That's the litmus test of our openness.

JIAOZI credentials are technical identity credentials for machine-to-machine trust. They claim no legal effect of an electronic signature and imply no endorsement by any government or regulator.
