Find USPS pickup points, compare USPS and UPS rates, track USPS packages. No sign-in.
Scored across 3 tools
Each tool maps to a clearly distinct action and resource: locating pickup locations, quoting rates, and tracking a package. Descriptions explicitly disclaim side effects (no label purchase, no reservation), so an agent cannot easily confuse them.
All three names follow a consistent snake_case verb_noun pattern (find_pickup_hubs, get_shipping_rates, track_package). Verb choices fit their actions naturally and no conventions are mixed.
Three tools is narrow but coherent for a read-only shipping lookup service, and each earns its place. It sits at the low end of what a shipping agent would expect, leaving little room for adjacent needs like label purchase or address validation.
The surface covers discovery, quoting, and tracking, but stops at lookups: there is no way to buy a label, create a shipment, validate addresses, or schedule a pickup despite the descriptions repeatedly noting these are unsupported. Tracking also fails for UPS numbers, an asymmetry with the UPS rate quotes.
Find nearby USPS Post Offices and Smart Lockers for package pickup/drop-off.
Returns each location's id, name, type, address and distance in miles. This is a look-up only; it does not buy a label or reserve anything.
Inputs: location (required), radius_miles.
Get shipping rates (postage cost and delivery time) for mailing a package with USPS or UPS home delivery, between two US addresses.
Returns each option's carrier, service, price in USD and estimated delivery time at the standard price. Quotes are indicative and not reserved. This tool only quotes prices; it does not buy a label.
Inputs: width_in (required), height_in (required), length_in (required), weight_lb (required), +10 more.
Look up the current status of a USPS package by its tracking number.
Returns the status, USPS's one-line summary, the expected delivery date and the latest scan
(what happened, when, and the city and state). The same information usps.com shows anyone who
has the number. USPS packages only: a UPS number gets an error pointing to ups.com.
Inputs: tracking_number (required).
