Pay per check (x402)

For an agent that holds a wallet. It pays for each check in USDC, inside the call itself, using the open x402 payment standard. No account, no sign-up, no key.

Prices

Check	Endpoint	Price
Token check	`POST https://api.lorglabs.com/v1/check/token`	$0.03
Address check	`POST https://api.lorglabs.com/v1/check/quick`	$0.01

Paid in USDC on Base. Your agent's wallet needs USDC only: the payment is a signed authorisation, so it needs no ETH for gas.

How it works

Ask
Send the request with no payment. The reply is 402 Payment Required, and its PAYMENT-REQUIRED header says the price, the network and where to pay.
Pay
Your agent signs a USDC payment for that amount with its own wallet, and sends the same request again with the payment in a PAYMENT-SIGNATURE header.
Receive
The signed answer comes back, with the payment's receipt in the PAYMENT-RESPONSE header.

An x402 client library does all three in one call.

The code

In JavaScript or TypeScript, with the x402 libraries (npm install @x402/fetch @x402/evm viem):

import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

// the agent's own wallet, holding USDC on Base
const wallet = privateKeyToAccount(process.env.AGENT_PRIVATE_KEY);
const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:*", client: new ExactEvmScheme(wallet) }],
});

// before the trade: ask, pay and receive, in one call
const reply = await fetchWithPayment("https://api.lorglabs.com/v1/check/token", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ chain: "base", address: token, amount_usd: 500 }),
});
const answer = await reply.json();

// act on one word
if (reply.status !== 200 || answer.action === "do_not_proceed") stop(answer.summary);

This exact code was run against the sandbox on 14 Oct 2026: paid, answered, receipt returned.

Clients for other languages (Python, Go and others) are listed by the x402 project. Any client that speaks x402 version 2 with the exact scheme works.

The sandbox takes the same payment in test USDC on Base Sepolia, which costs nothing (Circle's faucet gives it out). Point the same code at https://staging.lorglabs.com, and your wallet at Base Sepolia. The answers are real: the checks run on live mainnet data either way.

When you are never charged

A mistakeA malformed request is refused before any payment is asked for.
An errorAny reply with status 400 or above. The payment is settled only when we return an answer.
UnknownWhen a check we need can't finish, the reply is 503 CHECKS_INCOMPLETE: no verdict, no charge. Ask again after Retry-After.
A refundIf you believe you were charged wrongly, write to info@lorglabs.com with the receipt.

Limits

Without a key, one IP address can make 30 requests a minute, price questions and paid checks together. Beyond that the reply is 429 with Retry-After. An agent that needs more should hold a key.

Payments are verified and settled by Coinbase's x402 facilitator. Each one is public on the Base blockchain, like any other USDC transfer.
