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.k8s-dev.blockscout.com/:chain_id/api/v2/transactions?block_number=0&filter=string&hash=string&index=0&inserted_at=string&items_count=0&type=string'

# 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.k8s-dev.blockscout.com/:chain_id/api/v2/transactions?block_number=0&filter=string&hash=string&index=0&inserted_at=string&items_count=0&type=string' \
  | 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";

// Pays at most $0.002 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.002" });
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 $0.002 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fapi.k8s-dev.blockscout.com%2F%3Achain_id%2Fapi%2Fv2%2Ftransactions
const res = await pay("https://api.k8s-dev.blockscout.com/:chain_id/api/v2/transactions?block_number=0&filter=string&hash=string&index=0&inserted_at=string&items_count=0&type=string");
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.k8s-dev.blockscout.com/:chain_id/api/v2/transactions?block_number=0&filter=string&hash=string&index=0&inserted_at=string&items_count=0&type=string")
