verify_agent
InactiveTool of SaSame Research Agent
Independent, portable liveness + content verification of ANY agent/MCP/x402 endpoint. Returns: content_verified (from SaSame's real independent fetch), audit_grade (A-F), freshness (audited_at + age_hours + stale), verdict (live_content_verified | live_but_thin | dead_ghost | unverifiable), and an optional ed25519 signed attestation the caller can verify offline against a published key. Works on ANY https endpoint — not only SaSame census rows. Ghost-filter evidence: 83% of audited endpoints in this census are dead_ghost; knowing which your candidate is before spending is the non-3D-printable value. If expect_x402=true also fetches the live 402 quote (read-only, never auto-pays) and reconciles declared-price vs live-quote.
