x402 trending sellers

Momentum radar for the x402 seller ecosystem — which sellers are heating up, graded for wash-trade resistance. Reads the hourly on-chain leaderboard (real Base USDC settlements) and adds per-seller signals the raw board doesn't have: organicScore (uniqueBuyers/callsSettled — 1000 calls from 2 buyers smells like self-dealing, 1000 from 400 is organic demand) and avgTicketUsd. Rank by sort: 'usd' (revenue, default), 'calls' (volume), 'organic' (buyer diversity — the honest-demand lens), or 'buyers' (reach). include='external' (default) excludes Agent402's own row; 'all' keeps it. Once ~7 days of persisted snapshots accrue, each row also carries deltaVsPrevWeek + trend (rising/flat/cooling/new) — the wow envelope says whether those are live; deltas are never faked. ?sort=organic&limit=10

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/x402-trending?sort=usd&limit=10&include=external");
