is-real-biz
按调用付费的 API,告诉 AI 智能体某个域名是否为真实企业。 采用 MCP 优先构建。支持两种支付轨道:x402(自主、无需注册)+ 预付费积分(50 次免费检查,无需信用卡)。
🚀 在线体验:https://is-real-biz.is-real-biz.workers.dev — 立即尝试:
curl -X POST https://is-real-biz.is-real-biz.workers.dev/billing/signup \
-H 'content-type: application/json' -d '{"email":"you@example.com"}'
# returns: { api_key: "irb_live_...", credits_cents: 250 } — 50 free checksGET /check?domain=stripe.com → { verdict: "real", score: 94, signals: { ... } }使用场景:KYB / 供应商筛选、潜在客户资格审查、欺诈检查、尽职调查 —— 任何智能体需要知道“这个域名是合法企业还是停放/诈骗/虚假网站?”的场景。
为什么智能体能发现它
发现界面(特意过度服务 —— 每个智能体寻找的地方都不同):

此外,src/tool-descriptions.ts 中的工具描述是为基于嵌入的工具选择而编写的 —— 这是 Claude/ChatGPT/Cursor 实际选择调用哪个工具的方式。包含大量自然语言示例、用例标签和查询示例。

为什么智能体可以支付它
x402 (规范) —— 由 Coinbase + Cloudflare 推出的 HTTP 402 支付协议。智能体发送
X-PAYMENT标头,服务器通过中介在约 2 秒内验证并结算。无需注册。无需账户。支持分级调用。 默认网络是 Base Sepolia 测试网(免费)—— 在wrangler.toml中切换X402_NETWORK = "base_mainnet"即可进行真实支付。预付费积分 —— 使用电子邮件
POST /billing/signup将返回一个包含 50 次免费检查的 API 密钥。需要更多?在/billing/promo兑换运营商发放的促销代码。无需信用卡,无需 Stripe,无需绑定银行卡。
两条路径共享同一个 /check 端点,因此任何支持任一轨道的智能体都可以直接使用。
零成本部署(约 5 分钟)
你只需要:
一个免费的 Cloudflare 账户(workers.dev 子域名永久免费)—— 注册
一个免费的 Google AI Studio 密钥,用于 Gemini 1.5 Flash(无需信用卡)—— 获取密钥
然后:
git clone <this repo> is-real-biz && cd is-real-biz
npm run setup # runs deploy.sh — creates D1, KV, applies schema, sets secrets, deploys该脚本是交互式的:它会让你登录 Cloudflare,配置 D1 + KV,使用 ID 修补 wrangler.toml,询问你的 Gemini 密钥,并进行部署。你将拥有一个类似 https://is-real-biz.<your-subdomain>.workers.dev 的实时 URL。
手动部署
npm install
npx wrangler login
npx wrangler d1 create is-real-biz-db # paste id into wrangler.toml
npx wrangler kv namespace create CACHE # paste id into wrangler.toml
npx wrangler d1 execute is-real-biz-db --file=./schema.sql --remote
npx wrangler secret put GEMINI_API_KEY
npx wrangler deploy可选密钥
npx wrangler secret put ADMIN_TOKEN # to mint promo codes via POST /admin/promo
npx wrangler secret put X402_PAY_TO # your 0x address to enable x402 payments尝试一下
