3. Purchase a Domain

Step 1: Get Quote

When: User wants to buy a domain, get the price first.

GET https://clawdaddy.app/api/purchase/example.com/quote

{
  "domain": "example.com",
  "available": true,
  "priceUsd": 12.99,
  "marginUsd": 2.00,
  "totalUsd": 14.99,
  "validUntil": "2026-01-15T10:35:00.000Z",
  "paymentMethods": {
    "x402": { "enabled": true, "currency": "USDC", "network": "base" },
    "stripe": { "enabled": true, "currency": "USD" }
  }
}

Step 2a: Purchase via x402 (USDC on Base)

Best for: AI agents with crypto wallets

POST https://clawdaddy.app/api/purchase/example.com?method=x402

First request returns HTTP 402 with payment requirements:

{
  "error": "Payment Required",
  "x402": {
    "version": "2.0",
    "accepts": [{
      "scheme": "exact",
      "network": "eip155:8453",
      "maxAmountRequired": "14990000",
      "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
      "payTo": "0x..."
    }]
  }
}

After paying USDC on Base, retry with payment proof:

POST https://clawdaddy.app/api/purchase/example.com?method=x402
x-payment: 

Step 2b: Purchase via Stripe (Cards)

Best for: Human users or agents without crypto

POST https://clawdaddy.app/api/purchase/example.com?method=stripe
Content-Type: application/json
{
  "email": "user@example.com"
}

Returns Stripe checkout URL:

{
  "checkoutUrl": "https://checkout.stripe.com/...",
  "sessionId": "cs_..."
}

Success Response (Both Methods)

{
  "success": true,
  "domain": "example.com",
  "registrationId": "12345",
  "expiresAt": "2027-01-15T10:30:00.000Z",
  "nameservers": ["ns1.name.com", "ns2.name.com"],
  "managementToken": "clwd_abc123xyz...",
  "manageUrl": "https://clawdaddy.app/api/manage/example.com"
}

CRITICAL: Save the managementToken immediately! It's required for all management operations and cannot be retrieved without recovery.

Workflow Examples

Check and Buy Domain

User: "Buy coolstartup.com for me"
1. GET /api/lookup/coolstartup.com
   → available: true, price: $12.99
2. GET /api/purchase/coolstartup.com/quote
   → totalUsd: $14.99
3. POST /api/purchase/coolstartup.com?method=x402
   → 402 Payment Required
   → Pay USDC on Base
   → Retry with x-payment header
   → Success! Token: "clwd_abc123..."
4. "I've registered coolstartup.com! Save this token: clwd_abc123..."

Point Domain to Vercel

User: "Point mydomain.com to Vercel"
1. PUT /api/manage/mydomain.com/nameservers
   Authorization: Bearer clwd_abc123...
   {"nameservers": ["ns1.vercel-dns.com", "ns2.vercel-dns.com"]}
2. "Done! mydomain.com now uses Vercel's nameservers. Add the domain in your Vercel dashboard."

Set Up Basic DNS

User: "Point example.com to my server at 1.2.3.4"
1. POST /api/manage/example.com/dns
   Authorization: Bearer clwd_token...
   {"host": "@", "type": "A", "answer": "1.2.3.4", "ttl": 300}
2. POST /api/manage/example.com/dns
   {"host": "www", "type": "CNAME", "answer": "example.com", "ttl": 300}
3. "Done! example.com and www.example.com now point to 1.2.3.4"

Add Email Records

User: "Set up Google Workspace email for mydomain.com"

   {"host": "@", "type": "MX", "answer": "aspmx.l.google.com", "ttl": 300, "priority": 1}

   {"host": "@", "type": "MX", "answer": "alt1.aspmx.l.google.com", "ttl": 300, "priority": 5}

4. "Email records configured for Google Workspace!"

---

Error Handling

All errors return JSON:

{
  "error": "Description of what went wrong",
  "details": "Additional context if available"
}

| Status | Meaning | |--------|---------| | 400 | Bad request (invalid input) | | 401 | Unauthorized (missing/invalid token) | | 402 | Payment required (x402 flow) | | 404 | Domain not found | | 500 | Server error |

---

Key Points

No signup required for lookups and purchases

Two payment methods: x402 (USDC on Base) for agents, Stripe for humans

Save your management token - it's the only way to manage your domain

Bearer auth for management - include Authorization: Bearer clwd_... header

JSON responses - use ?format=json for lookups
