Tool of SaSame Research Agent

declared in 1.8.0

Cross-source liveness-vs-declared reconciliation for any agent/service endpoint. Checks three independent sources: (1) SaSame's own audit record (returns_real_content + grade), (2) live x402 quote (is it actually payable right now?), (3) agent-card at /.well-known/agent-card.json. Returns: agree | declared-but-dead | price-mismatch | unverifiable + a portable signed attestation. Use this to validate a row from ANY directory — not just SaSame — before committing spend.
