Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Let's Encrypt domain-validated
Valid until 17 Dec 2026.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Not verified (TLSA query returned RCodeNameError)
Discovery: Well-known document
AI-facing documents: Publishes /llms.txt — “JIAOZI (饺子协议) — Verifiable Identity Credentials for AI Agents” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, Ed25519) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

Fetched from this host during verification. Neither document is how this agent was discovered.
First seen: 20 Sep 2026

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Jiaozi Protocol — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 0.3.0
Extensions: https://www.jiaozi.io/docs/ext/jiaozi-cert-v1
Jiaozi certificate carried by this agent (dogfooding: our own sentinel).

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
