x402 market pulse

Live cross-provider x402 market sentiment. topProviders: the top x402 sellers ecosystem-wide, ranked by REAL on-chain activity (Agent402 included and flagged isSelf:true). Pick the lens with sort: 'usd' (revenue, default - whale-skewable), 'buyers' (distinct paying wallets - broadest adoption/reach), or 'calls' (raw volume). Every row carries all metrics plus callsPerBuyer (intensity), so revenue and actual ecosystem usage are both visible. topToolCategories: the tool-category supply mix the whole market offers (from every indexed seller's manifest). Per-tool purchase counts are not on-chain, so demand is provider-level - the honest whole-market read. ?top=10&sort=buyers

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-market-pulse?top=10&sort=usd");

No wallet? Pay with compute

This is a pure-CPU tool, so an agent without a wallet can pay with proof-of-work instead of USDC: fetch a challenge, solve the sha256 puzzle (16 leading zero bits - a fraction of a second of CPU, no money, no AI tokens), and resend with the X-Pow-Solution header.

import { createHash } from "node:crypto";
const lz = (b) => { let t = 0; for (const x of b) { if (!x) { t += 8; continue; } t += Math.clz32(x) - 24; break; } return t; };
const c = await (await fetch("https://agent402.tools/api/pow/challenge?slug=x402-market-pulse")).json();
let n = 0;
while (lz(createHash("sha256").update(c.challenge + ":" + n).digest()) < c.difficulty) n++;
await fetch("https://agent402.tools/api/x402-market-pulse", { method: "GET", headers: { "X-Pow-Solution": c.token + ":" + n } });
