Perp Gap API

Use before sizing a tokenized-stock trade or choosing between xStocks and Ondo for execution. For one ticker: each token's Solana pool liquidity, price impact of a $10k buy and sell, rough size executable within 1%, a tradable flag, and Ondo's issuer mint/redeem market. Bad params return 400/404 before any charge. Errors: 400, 402, 404, 502. Data, not advice.

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://perp-gap-api.perpgap.workers.dev/tokens/liquidity", { method: "GET" });
console.log(await res.json());
