概览
BountyAPI MCP 服务器,为 AI 助手提供新加坡房产与金融数据工具,付费端点可选 USDC 微支付自动结算。
- 可以做什么
- 按买家身份计算新加坡房产印花税(BSD 与 ABSD),并给出分档明细,数据来源为 IRAS(免费)。将新加坡邮编查询到 28 个邮区(免费)。计算租金投资指标,如毛收益率、净收益率、资本化率、租售比与现金流(付费)。按城镇和房型获取组屋转售中位价,并按城镇、房型和价格区间检索单笔组屋转售交易(付费)。配置钱包密钥后,付费调用会在 Base 上以 USDC 自动结算。
- 适用场景
- 适合需要新加坡房产数据的场景:印花税估算、邮区查询、租金收益率计算或组屋转售价格调研。免费工具无需钱包即可使用;付费工具适合希望按次自动购买数据的用户。
- 运行要求
- 可作为远程端点使用,也可通过 npx 以本地 npm 包(bountyapi-mcp)运行,需要 Node.js。需要能访问该 API 的网络。付费端点需要 Base 上存有 USDC 的钱包及环境变量 EVM_PRIVATE_KEY;MAX_SPEND_USD 限制单次请求花费(默认 1.00),BOUNTY_API_URL 可覆盖基础地址。

MCP server for BountyAPI — specialist data APIs for AI agents with x402 micropayment support.
Connect AI agents (Claude Desktop, Cursor, etc.) to BountyAPI endpoints at https://bountyapi.com. Free endpoints work out of the box. Paid endpoints require a funded wallet — the agent pays automatically per request.
Quick Start
Free tools only (no wallet needed)
With payment support (paid endpoints auto-pay)
- Create a burner wallet on Base with $2-5 of USDC
- Export the private key
- Configure:
Or via CLI:
Then ask your AI:
"What's the stamp duty for a $1.5M property in Singapore for a Singapore Citizen buying their first home?"
"Search for recent HDB resale transactions in Tampines, 4 ROOM only"
"What's the rental yield on a $1.2M condo renting at $4,200/month?"
How Payments Work
When an agent calls a paid endpoint:
- Server returns
402 Payment Requiredwith payment instructions - MCP server reads the price and checks against
MAX_SPEND_USD - If within limit, it signs a USDC transfer on Base and retries
- Server verifies payment via facilitator and returns data
- Settlement is logged with a Basescan transaction link
The agent never sees the payment — it just gets the data. Cost: ~$0.01 per paid call.
Available Tools

Environment Variables
Safety
- Never use your main wallet. Create a dedicated burner wallet with only a few dollars of USDC on Base.
- The
MAX_SPEND_USDlimit prevents unexpected charges — each request is checked before payment. - Private keys are never logged or transmitted to the API server. They only sign local payment authorizations.
