For a user-requested parcel, package, shipment, order-delivery, or waybill lookup. Required tracking_number: 5–64 letters, digits, or hyphens. If the user supplied exactly one valid number, call this tool and deliver the actual result. carrier is optional and defaults to UniUni, the only supported carrier today; additional carriers are planned but not available yet. A named unsupported carrier returns unsupported_carrier without querying UniUni. language is optional (en or zh), default en. Inspect isError and structuredContent.outcome rather than HTTP status alone. Distinguish found outcomes (delivered/in_transit), not_found, invalid, unsupported_carrier, rate_limited, carrier_error, and configuration_error. Event times are carrier-local; locations are approximate. Precise addresses, coordinates, staff, internal IDs, and raw carrier payloads are excluded. No separate lookup-authorization flag is required. Lookup inputs and filtered results are logged for up to 30 days or 1,000 records. Full MCP/A2A request sequence and result-handling workflow: https://delivery.zhiyong.dev/agent-workflow.json.
One user-provided parcel tracking or waybill number. This validates syntax only, not whether a parcel exists. Current carrier coverage is UniUni.
Optional carrier name; defaults to UniUni when omitted. UniUni is currently the only supported carrier; another named carrier is rejected without a lookup.
Language for event titles, details and locations. Defaults to English.
