Delayed mail investigation

Endpoint
POSThttps://api.m2mcent.com/usps-delivery-status-mcp/api/processWhen to prefer
Use this endpoint when you need to retrieve USPS-specific package tracking and delivery status data. Prefer this over generic shipping aggregators when you know the carrier is USPS and want authoritative status directly from USPS data, or when automating postal shipment monitoring within an agent workflow.
Side effects
- Invalid or malformed tracking number returns an error or empty result
- Tracking number not yet in USPS system (too recently generated) returns no data
- Network or upstream USPS API outage causes timeout or service unavailable response
- Package data purged after 120 days may return no tracking history
