A decision loop your agent can run.

Free status tells an agent whether movement is likely material. Changes names the evidence. The brief turns that evidence into an action.

04FIRST PAID CALL

Make one safe, recoverable paid request.

Start with the parameter-free $0.01 snapshot. The pinned x402 v2 client requests the route, signs only the returned Base-mainnet requirement, and retries once. Never paste a funded key into this page or commit it to source control.

02Sign the exact returned requirement
03Verify delivery and payment response

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

const privateKey = process.env.EVM_PRIVATE_KEY;
if (!privateKey?.startsWith("0x")) throw new Error("Set EVM_PRIVATE_KEY");

const account = privateKeyToAccount(privateKey);
const paidFetch = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{
    network: "eip155:8453",
    client: new ExactEvmScheme(account),
  }],
});

const response = await paidFetch(

if (!response.ok) {
  throw new Error(response.status + ": " + await response.text());
}

console.log(JSON.stringify({
  paymentResponse: response.headers.get("payment-response"),
  body: await response.json(),
}, null, 2));

Client flow follows the official x402 buyer quickstart . Review the code and use a purpose-limited wallet.

RECOVER BY STATUS — DO NOT BLINDLY LOOP

400: The request contract or parameter is invalid. Fix it before signing or retrying; this is not a paid delivery.
402: An unsigned call is expected. If a signed retry still returns 402, inspect scheme, network, amount, and wallet funds before another attempt.
200: Parse the JSON delivery and retain the PAYMENT-RESPONSE header as the settlement receipt.

ARE YOU HUMAN?

A small design-partner cohort is open.

SatsSignal is for x402 builders with a live product decision: check status for material movement, inspect changes when something moved, then use the brief to decide whether to build, reprice, reposition, monitor, or retire. We are working closely with 3–5 builders during this test; partners get direct interpretation of the evidence and influence over the contract, with no subscription or lock-in.
