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.", "body_md": "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.\n\nSo 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`\n\nwith the price, pays a couple cents of USDC, and replays the request. That's it.\n\n```\nnpx skills add epistemedeus/x402-data-gateway-skills --all\n```\n\nThat 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.\n\n** company-enrich** — a domain → clean firmographics (name, description, tech stack, socials, contact),\n\n** wallet-enrich** — a Base/EVM\n\n`0x`\n\naddress → on-chain profile: EOA vs contract, native + token holdings, ERC-20/721/1155 metadata, EIP-1967 proxy detection, activity, and the `jesse.base.eth`\n\n), forward-confirmed so it's never wrong. The crypto-native counterpart for sizing up a counterparty before you transact.\n\n``` js\nimport { wrapFetchWithPayment } from \"x402-fetch\";\n// walletClient = a viem wallet funded with a little USDC on Base\nconst fetchPaid = wrapFetchWithPayment(fetch, walletClient);\n\nconst res = await fetchPaid(\n  \"https://x402-url-extractor-production.up.railway.app/wallet-enrich?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913\"\n);\nconsole.log(await res.json());\n// -> { type: \"contract\", contract: { standard: \"ERC-20 (token)\", token: { symbol: \"USDC\", ... } }, profile: \"token-contract:USDC\" }\n```\n\nSettlement is non-custodial: the facilitator verifies your signed EIP-3009 authorization and the USDC moves straight to the service wallet. Nobody holds your funds.\n\nPrefer MCP? The same tools are an x402-gated MCP server (`tools/list`\n\nis free, `tools/call`\n\nis paid), listed in the official MCP Registry as `io.github.epistemedeus/x402-data-gateway`\n\n. `tools/list`\n\nto see all six; pay-per-call on the ones you use.\n\n| Skill | Does | Price |\n|---|---|---|\n| company-enrich | domain → company intel + AI-readiness + DNS | $0.02 |\n| wallet-enrich | 0x address → on-chain profile + Basename | $0.02 |\n| web-extract | URL → structured JSON or LLM-ready Markdown | $0.05 |\n| repo-security-scan | static supply-chain scan of a GitHub repo before you install it | $0.20 |\n| schema-generate | business site → paste-ready JSON-LD bundle | $0.25 |\n\nPublic data only, deterministic, pay-per-call.
