Live USPS, UPS & FedEx shipping rates plus USPS postage and stamp prices for any US parcel or letter. Free, no API key, no signup.
Two read-only tools:
- get_shipping_rates — compare carrier rates between US ZIP codes (and international), cheapest first
- get_postage_price — USPS postage with Forever-stamp counts and exact stamp combinations for letters, large envelopes, and postcards
Rates are discounted online-postage prices, not retail counter prices.
