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.

```
npx skills add epistemedeus/x402-data-gateway-skills --all
```

That drops in [Agent Skills](https://github.com/vercel-labs/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.

``` js
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.
