Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.0025.

The code pays $0.0025 in USDC on Base instead: it uses a payment scheme other than exact, which needs a different client setup.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://x402.ochinimus.app/api/paper/10.1038%2Fnature14539'

# 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://x402.ochinimus.app/api/paper/10.1038%2Fnature14539' \
  | 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 { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.0025 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.0025" });
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 $0.0025 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fx402.ochinimus.app%2Fapi%2Fpaper%2F10.1038%252Fnature14539
