ghostkey_catalog ~95 tokens
List this embedded GhostKey interface's exposed tool names and monetization policy. Returns the canonical paid catalog and quote-authority pointers. Use for discovery; no paid work is executed or billed here.
ghostkey_policy ~113 tokens
Read the embedded GhostKey discovery/payment policy and upstream-rights rules. Returns charges_here=false, the canonical paid authority and explicit boundaries. Use to understand permitted discovery; it does not grant browser access, credentials or spending authorization.
ghostkey_quote ~153 tokens
Return pre-spend guidance for a named capability, with charged=false and payment_is_delivery=false. Use to locate the canonical paid execution authority and request its fresh 402 quote. This response is guidance, not an executable price quote or settlement receipt.
ghostkey_status ~111 tokens
Read the embedded GhostKey discovery role, hosting and live payment-authority envelope. Use before selecting SML paid execution. This embedded helper is free discovery, not the standalone browser-session action surface; it never signs, spends or claims paid delivery.
