As REST API

curl https://tools.beethoven2024.com/health
# {"status":"ok","version":"0.1.0"}

curl "https://tools.beethoven2024.com/v1/dns/health?domain=example.com"
# Full DNS + mail security audit (requires x402 payment)

What's in the bundle

| Tool | Endpoint | What it does | Price | |------|----------|-------------|-------| | qr_generate | /v1/qr/generate | QR code generation (PNG/SVG, 64–2048px) | $0.001 | | dns_health | /v1/dns/health | DNS records + SPF/DMARC mail security audit | $0.003 | | email_validate | /v1/email/validate | Format, MX, disposable domain, role account, SMTP probe | $0.005 | | ip_lookup | /v1/ip/lookup | Geolocation, ISP, proxy/hosting detection, reverse DNS | $0.005 | | url_health | /v1/url/health | Status code, redirect chain, SSL cert, response time | $0.003 | | whois_lookup | /v1/whois/lookup | Registrar, creation/expiration dates, nameservers, status | $0.005 | | headers_analyze | /v1/headers/analyze | HTTP security headers audit with 0–100 score (HSTS, CSP, etc.) | $0.003 | | extract_text | /v1/extract/text | Clean text extraction from webpages (strips HTML, nav, ads) | $0.005 | | tech_detect | /v1/tech/detect | Website technology stack — frameworks, CMS, CDN, analytics | $0.005 |

Free: /health, /, /docs (OpenAPI), and MCP protocol methods initialize / tools/list / ping. All 9 tools require x402 payment via both MCP (tools/call) and REST (/v1/*).

Why these endpoints

Every endpoint solves a problem agents can't easily do locally:

• Network infrastructure (DNS, WHOIS, headers, URL health, IP) — needs internet probes, can't be done in-process
• Specialized parsing (QR, email validation with SMTP, tech detection) — domain-specific logic agents shouldn't reimplement
• Web extraction (text extraction) — clean text from messy HTML is hard

8 of 9 endpoints are fully self-hosted (zero upstream API cost). Only IP geolocation uses an external free-tier API.

Payment

x402 (machine-to-machine micropayments)

Every paid endpoint returns HTTP 402 Payment Required with the price spec when no payment is included. x402-capable agents handle this automatically:

1. Agent calls endpoint → receives 402 with payment_requirements (network, amount, recipient address)
2. Agent signs EIP-3009 transferWithAuthorization for USDC on Base
3. Agent retries with X-PAYMENT header
4. Service verifies payment via facilitator, executes, returns result

Settlement happens on-chain on Base. Sub-2-second confirmation.

Runs on Base mainnet by default. Set AGENT_TOOLS_TESTNET=true to use Base Sepolia with the public testnet facilitator.

Traditional billing

Coming soon: API key + Stripe usage billing for human developers and businesses.

Tech stack

• Python 3.12 + FastAPI
• MCP SDK (mcp v1.27) — streamable-http transport
• x402 SDK (x402[fastapi,evm] >=v2.11) — USDC micropayments on Base
• 8/9 endpoints self-hosted (no upstream API cost)
• Single-process deploy, ~62MB memory footprint

Configuration

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | AGENT_TOOLS_PAY_TO | No | (empty) | EVM wallet address for receiving USDC payments. Leave empty to run free/dev mode. | | AGENT_TOOLS_TESTNET | No | true | true = Base Sepolia testnet (default — works with public x402.org facilitator). false = Base mainnet (requires mainnet-capable facilitator). |
