Agent402 bestsellers

What agents actually pay for on a 500+ tool x402 catalog — the paid intelligence layer over Agent402's own sales ledger, the one demand signal that never reaches the chain (settlements are on-chain; WHICH tool was bought is not). The raw merchant feed stays free at /api/sales; this adds the analysis it doesn't have: pick the window (days 1-90) and the ranking lens with sort: 'buyers' (distinct paying wallets, default — the whale/wash-resistant read), 'sales' (volume), 'usd' (revenue), or 'organic' (buyers-per-sale diversity grade, same metric as x402-trending); every row carries all lenses plus organicScore, avgTicketUsd, revenueShare, and a trend vs the previous same-length window (deltaSales + rising/flat/cooling/new — never faked: a row with no prior-window sales says 'new'). Canary/burner/heartbeat traffic is excluded at the source, and if this tool ranks in its own chart the row is flagged isSelf:true rather than hidden — buying the chart puts you on the chart. ?sort=buyers&days=30&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/bestsellers?days=30&sort=buyers&limit=10");
