GhostBench/kyv-attest defines a signed, machine-verifiable attestation convention for vendor aliveness and operational facts, anchored in a transparency log, to help AI agents determine whether a SaaS vendor is still real. The accompanying benchmark shows that dead SaaS domains often return HTTP 200 and that small models misjudge vendor viability, motivating signed continuity as a stronger signal. It is interesting because it targets a real gap in agent infrastructure—vendor trust and liveness—rather than another API wrapper.

Target audience: backend developers, AI agent developers, platform engineers, security engineers
