Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.025.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://mpp.tracefast.xyz/api/v1/chains/1/consensus/queues?limit=10'

# 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://mpp.tracefast.xyz/api/v1/chains/1/consensus/queues?limit=10' \
  | 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";
import { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.025 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.025" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, 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 $0.025 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fmpp.tracefast.xyz%2Fapi%2Fv1%2Fchains%2F1%2Fconsensus%2Fqueues
const res = await pay("https://mpp.tracefast.xyz/api/v1/chains/1/consensus/queues?limit=10");
