Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $1.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.stacktr.ee/provision' \
  -H 'content-type: application/json' \
  --data-raw '{}'

# 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 - -X POST 'https://api.stacktr.ee/provision' \
  -H 'content-type: application/json' \
  --data-raw '{}' \
  | 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 $1 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$1" });
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 $1 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fapi.stacktr.ee%2Fprovision&method=POST
const res = await pay("https://api.stacktr.ee/provision", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({}),
});
console.log(res.status, await res.text());
Python: pay and call
# pip install "x402[requests,evm]"

client = x402ClientSync().set_spend_controls({"max_amount_per_payment": "$1"})
register_exact_evm_client(client, EthAccountSigner(Account.from_key(os.environ["EVM_PRIVATE_KEY"])))

with x402_requests(client) as session:
