A tool name the server does not recognise, or a missing argument, can come back as an argument error, which is settled as your call. No template is printed here, because a copied placeholder name is a call the server cannot route: get_service with includeSchemas:true returns the real argument names and types (toolSchemas, for up to 40 of a server's tools), free. \"seller-settled\" means this listing's server charges with its own x402 paywall: the 402 you get is the SELLER's own requirement, paid straight to its wallet and settled by its server — FiatDock relays it, takes no fee, and its deliver-then-settle guarantee does not apply.

Values: \"listing_tool_missing\" (sells a tool its own server did not report), \"listing_tool_unset\" (names no tool — see callableVia), \"endpoint_unreachable\" (did not answer the last check, which can be hours old), \"endpoint_dormant\" (silent for days), \"endpoint_cannot_route_tool_calls\" (answers every request with its handshake), \"endpoint_demands_its_own_payment\" (its server charges with its own x402 paywall — with callableVia \"seller-settled\" it is bought on the seller's own terms through FiatDock's relay), \"seller_payout_unset\" and \"seller_payout_unspendable\" (no usable payout wallet — the gateway refuses before any price), \"listing_suspended\" (the gateway refuses).
