Last Price

report_outcome

Report whether a price from compute_price was used: once the buyer has accepted or turned down a price, report it. Pass receipt.id from that result as usage_event_id, or omit it to report the last price compute_price returned on this connection or tools instance, once (the hosted MCP endpoint remembers nothing, so pass it there). Outcomes are what later routing and confidence learn from. With outcome pricing on, a rejection within the call's outcome window gives back part of what it cost; the result says what was refunded. Needs a Last Price credential. Report only what actually happened. Needs a claimed workspace: a sandbox key from self-registration is refused (403) until a person claims the workspace.
