PAID. Use when asking "is this agent endpoint safe to call?" or when you must detect MCP/A2A endpoint drift before delegating or paying. Returns live checks PLUS drift history, cross-source corroboration and an explicit allow / caution / block policy verdict you can act on directly. The free `guild_preflight` is not degraded to sell this — it still returns the full live check set. This adds what one request cannot establish: whether the endpoint has CHANGED, and whether anyone else corroborates it. Priced through the same gateway as every other paid read (see GET /pricing). After a payment-required response, retry with the official `_meta['x402/payment']` carrier. If an MCP adapter cannot set request metadata, pass the identical PaymentPayload through the schema-visible `x402_payment` fallback. Conflicting carriers fail closed before settlement.
