x402 APIPassing, checked 52 min ago

Strait of Hormuz bunker & marine-fuel feed: current VLSFO, IFO380, and MGO prices ($/tonne) for Fujairah (the world's #2-3 bunkering hub, just outside the strait and the physical fueling alternative when transit is disrupted), benchmarked against Singapore and Rotterdam, plus the derived Fujairah premium over each comparison hub. The physical-commodity read on Hormuz stress that the Brent and insurance signals do not capture.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://straits.live/api/premium/bunker'

# 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://straits.live/api/premium/bunker' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
