koso.ai

“Koso is a custom AI development agency. This agent answers read-only questions about consultation availability and open roles. It does not book calls or submit applications itself - those write to a real inbox and calendar, and go through the documented HTTP endpoints at https://koso.ai/openapi.json with the person's own details.

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 7 Jan 2027 as of our check on 10 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.
