Semanto™
A signed, machine-readable copy of your website that AI agents can read and verify
Semanto™ lets companies publish a signed, machine-readable version of their website that AI agents can read and verify for accuracy.
Overview
The Semanto™ homepage
Semanto™ makes AI answers about companies more accurate by providing a signed, machine-readable copy of a company's website that AI agents can read and check. The service is hosted by Trooth on api.trooth.co and can be served from a company's own domain through an adapter. Companies can set up Semanto™ on various hosting platforms including Cloudflare, Vercel, Netlify, Fastly, Akamai, nginx, Apache, WordPress, Shopify, Webflow, Squarespace, and Wix. AI agents can run Semanto™ setup and management through MCP integrations with tools like Claude, ChatGPT, VS Code, Cursor and others. The platform provides 77 tools organized in 14 groups for building, publishing, and managing signed website copies, along with public routes for reading company records and verifying signatures.

Buyer questions
What does Semanto™ require before starting?
Semanto™ requires a published Trust Profile. The signed copy points readers to the profile, and signing waits until the profile is published. You must finish your Trust Profile in Quick Start first.
How can an AI agent help set up Semanto™?
An AI agent can run most of Semanto™ including setup, domain proof, signing, site installation, settings, signing key rotation, Google integration, seller lists, recalls, read receipts and reports. Setup, domain proof, signing and site installation can be done in the dashboard. Four things only a person can do when signed in to trooth.co: erasing Semanto™, making agent keys, turning two-officer signing off and approving apps.
What happens when Trooth is slow or unavailable?
An adapter never takes your site down. It waits at most 1.5 seconds for a file and uses a stored manifest immediately. When Trooth is slow, unreachable or returns a server error, it serves the last good copy while its signature is valid, then the same copy without signature, or your own page. After three failures in 30 seconds, it stops asking for 30 seconds.
How do people verify Semanto™ signatures?
Published keys let anyone check a signature without an account or conversation. Trooth signs what it read, never a company's claims. Readers can use the /public/semanto/verify route to check a copy against the signed version.
