Logistics Last Mile Courier

by SiteCheck Trade & Energy in Email & messaging

x402 APIFailing, checked 4 h ago

Identify the courier behind a tracking number (UPS, FedEx, USPS, DHL Express, DPD, Royal Mail and other national posts) from its format, check the check digit where the carrier publishes one, and return the carrier's official tracking link. Several carriers can match the same pattern; each candidate says whether its check digit passed. It does not read live scan events (carriers serve them only through their own sites or keyed APIs).

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.tradeenergy-api.workers.dev/api/logistics/last-mile-courier?number=1Z999AA10123456784'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
