If you're building autonomous agents, you've hit this wall: your agent needs to enrich a company by domain or size up a wallet before it sends funds, but every good data source (Clearbit, Apollo, Nansen) is signup- and KYC-gated. An autonomous agent can't click "Sign up," verify an email, and paste an API key.
So I put a small data gateway behind x402 — HTTP 402 + pay-per-call USDC on Base. No account, no API key, no subscription. Your agent does a GET, gets a 402
with the price, pays a couple cents of USDC, and replays the request. That's it.

That drops in Agent Skills that teach your agent when to call each endpoint — so "enrich this company" or "profile this wallet" just works.
** company-enrich** — a domain → clean firmographics (name, description, tech stack, socials, contact),
** wallet-enrich** — a Base/EVM
0x
address → on-chain profile: EOA vs contract, native + token holdings, ERC-20/721/1155 metadata, EIP-1967 proxy detection, activity, and the jesse.base.eth
), forward-confirmed so it's never wrong. The crypto-native counterpart for sizing up a counterparty before you transact.
import { wrapFetchWithPayment } from "x402-fetch";
// walletClient = a viem wallet funded with a little USDC on Base
const fetchPaid = wrapFetchWithPayment(fetch, walletClient);
const res = await fetchPaid(
"https://x402-url-extractor-production.up.railway.app/wallet-enrich?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"
);
console.log(await res.json());
// -> { type: "contract", contract: { standard: "ERC-20 (token)", token: { symbol: "USDC", ... } }, profile: "token-contract:USDC" }
Settlement is non-custodial: the facilitator verifies your signed EIP-3009 authorization and the USDC moves straight to the service wallet. Nobody holds your funds.
Prefer MCP? The same tools are an x402-gated MCP server (tools/list
is free, tools/call
is paid), listed in the official MCP Registry as io.github.epistemedeus/x402-data-gateway
. tools/list
to see all six; pay-per-call on the ones you use.

If you wire it into an agent, I'd genuinely like to hear what task you used it for.
