Postal Ninja is a consumer web lookup with no developer API—lastscanned gives you a JSON API & MCP server.

Postal Ninja is a popular consumer website for checking cross-border and postal tracking numbers manually in a browser, but it offers no public REST API, no webhooks, no SLA, and no AI agent integration. lastscanned gives developers and AI agents a synchronous GET /v1/track/:number JSON API, batch endpoint, remote MCP server, and Stripe MPP support across 125 carriers—including the exact same consolidator handoff extraction.

Programmatic handoff extraction in JSON (message field)

Shoppers love Postal Ninja because it shows secondary final-mile tracking numbers when Cainiao, YunExpress, Yanwen, 4PX, or ePost Global hands a parcel to USPS, UniUni, SpeedX, or Royal Mail. lastscanned brings that exact capability to your backend and AI agents via a clean JSON field.

Automatic last-mile barcode extraction
When an origin consolidator assigns a destination barcode (e.g. USPS 92…, UniUni UUS…, SpeedX SPX…, Evri H00…), lastscanned surfaces it in the top-level message string.
Up to 100 tracking numbers in one HTTP call
Instead of manually typing barcodes into a consumer search box, call GET /v1/track?numbers=num1,num2,... to resolve up to 100 parcels in parallel.

Built for Shopify WISMO, Gorgias, and AI agents

Whether you are replacing manual support-team lookups on Postal Ninja or building an autonomous WISMO agent, lastscanned drops in with zero infrastructure.
