Logistics Container Tracking

by SiteCheck Trade & Energy in Developer tools

x402 APIFailing, checked 15 min ago

Shipping container number check: validates an ISO 6346 container number (owner code, category, serial, check digit, computed locally), names the owner of the prefix (e.g. MSKU = Maersk) with country and website from the public prefixlist.com register, and returns links to the owner's and track-trace.com's tracking pages. It does not read the container's live milestones (carriers publish them on their own sites).

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/container-tracking?container=MSKU1234565'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.tradeenergy-api.workers.dev/api/logistics/container-tracking?container=MSKU1234565' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
