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/alaska-marine-highway?month=2026-11&schedule=SE+Mainlines'

# 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/alaska-marine-highway?month=2026-11&schedule=SE+Mainlines' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode

JavaScript: pay and call

// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
// client: this one is capped at $0.002 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fapi.tradeenergy-api.workers.dev%2Fapi%2Flogistics%2Falaska-marine-highway
const res = await pay("https://api.tradeenergy-api.workers.dev/api/logistics/alaska-marine-highway?month=2026-11&schedule=SE+Mainlines");
