Find paid APIs, check access policy and price, and route x402 requests. No autonomous spending.
Scored across 4 tools
catalog and status heavily overlap — both promise 'free pre-spend' info plus the 'canonical paid execution authority,' making them hard to tell apart. policy and quote are more distinct, but quote oddly only explains how to get pricing rather than returning it.
All four tools use a consistent ghostkey_<noun> pattern (catalog, policy, quote, status), which is predictable and readable.
Four tools is thin for a server whose stated purpose is routing paid APIs; the count is defensible only if this is purely a metadata/discovery layer, but it feels under-scoped.
The domain is executing/routing paid x402 APIs, yet every tool is descriptive metadata (catalog, policy, quote, status) with no tool that actually invokes, quotes, or settles a paid route — a dead end for the core workflow.
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.

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.

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.

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.
