Weekly port congestion figures for one port from Portcast's public port page: median waiting time (days), average vessels waiting per day, congestion category and week-on-week change. Free public page data (not the paid API), and only for ports Portcast publishes; the slug is the port name in lowercase, e.g. ako or long-beach.

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/port-congestion-index?port=long-beach'

# 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/port-congestion-index?port=long-beach' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
