Give your AI agent company + on-chain wallet enrichment in 30 seconds (x402, pay-per-call USDC)

A developer built a data gateway behind x402 (HTTP 402 + pay-per-call USDC on Base) that lets autonomous agents enrich company domains and on-chain wallets without signup or API keys. The gateway offers endpoints for company enrichment, wallet profiling, web extraction, repo security scanning, and schema generation, with settlement via non-custodial EIP-3009 authorization. The tools are available as Agent Skills and an MCP server, enabling agents to pay a few cents per call for deterministic public data.

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. | Skill | Does | Price | |---|---|---| | company-enrich | domain → company intel + AI-readiness + DNS | $0.02 | | wallet-enrich | 0x address → on-chain profile + Basename | $0.02 | | web-extract | URL → structured JSON or LLM-ready Markdown | $0.05 | | repo-security-scan | static supply-chain scan of a GitHub repo before you install it | $0.20 | | schema-generate | business site → paste-ready JSON-LD bundle | $0.25 | Public data only, deterministic, pay-per-call.
