Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.aventtech.com/parse/useragent?ua=Mozilla%2F5.0+%28iPhone%3B+CPU+iPhone+OS+17_5+like+Mac+OS+X%29...'

# 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.aventtech.com/parse/useragent?ua=Mozilla%2F5.0+%28iPhone%3B+CPU+iPhone+OS+17_5+like+Mac+OS+X%29...' \
  | 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 $0.01 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.01" });
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 $0.01 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fapi.aventtech.com%2Fparse%2Fuseragent
const res = await pay("https://api.aventtech.com/parse/useragent?ua=Mozilla%2F5.0+%28iPhone%3B+CPU+iPhone+OS+17_5+like+Mac+OS+X%29...");
console.log(res.status, await res.text());
Python: pay and call
# pip install "x402[requests,evm]"

register_exact_evm_client(client, EthAccountSigner(Account.from_key(os.environ["EVM_PRIVATE_KEY"])))

with x402_requests(client) as session:
    res = session.get("https://api.aventtech.com/parse/useragent?ua=Mozilla%2F5.0+%28iPhone%3B+CPU+iPhone+OS+17_5+like+Mac+OS+X%29...")
