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 Google Trust Services domain-validated
Valid until 24 Jan 2027 as of our check on 9 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of femtech.horizonshield.dev controls every word below.

Femtech information source registry

Verifies and indexes femtech (women's health) information sources by provenance, authority tier, jurisdiction and compensation disclosure. Send a URL or a publisher name as a text part and get back who publishes it, in what capacity, and whether a conflict of interest is disclosed. Never rules on whether a claim is true.

Third-party verification of a registry entry

Recomputes the canonical bytes and SHA-256 of a registry entry and compares them with the stored provenance. Fail closed. Untampered is not the same as medically true.

Protocol: a2a
Version: 0.4.1
Extensions: https://gate.horizonshield.dev/ext/conduct/v1
Who pays this agent, where its measured conduct record lives, and where to file a witness walk. The specification is served at the URI.

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: complete all eight fields required by a2a.proto v1.0
