Solana Pulse

Use on every transaction before your agent signs it. Shows exactly what each wallet gains and loses, blocks drainer patterns, and catches failures and expired blockhashes before any fee is spent. Decodes every instruction, simulates the transaction against live state, computes each wallet's SOL and token changes, and returns OK, REVIEW or BLOCK with reasons.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/preflight_transaction", { method: "POST" });
console.log(await res.json());
