Agent Domain Search

# Agent Domain Search > Agent-first domain registration and DNS management. Check availability, register domains, and manage DNS via JSON API. Pay with USDC on Base via x402. No accounts, no API keys — wallet signatures and inline payments only. ## Quick Start 1. Check availability: GET https://agentdomainsearch.com/example.com 2. Get suggestions: GET https://agentdomainsearch.com/suggest?q=myproject 3. Register: POST https://agentdomainsearch.com/example.com (x402 USDC payment) 4. Manage DNS: PUT https://agentdomainsearch.com/example.com/dns (wallet auth) ## Authentication Sign "agentdomainsearch.com:<unix-timestamp>" with EIP-191 personal_sign. Token: <timestamp>.<130-hex-char-signature> (strip 0x prefix). Valid 5 minutes. Send as: Authorization: Bearer <token> ## Payment (x402) Network: base | Asset: USDC | Facilitator: https://api.cdp.coinbase.com/platform/v2/x402 Manifest: https://agentdomainsearch.com/.well-known/x402.json ## Pricing `price` in check/price responses is per-year retail (USDC). Total = `price × period`. Some TLDs require multi-year registration; `min_period` in responses indicates the minimum (e.g. 2 for .ai). POST /:domain defaults `period` to `min_period` and rejects lower values with 400. ## Example: Register a domain Two-step x402 flow. First call returns 402 + payment details; sign the EIP-3009 authorization with your wallet, base64-encode the x402 payload, then retry with the PAYMENT-SIGNATURE header. curl -X POST https://agentdomainsearch.com/example.com \ -H "Content-Type: application/json" \ -H "PAYMENT-SIGNATURE: <base64(JSON.stringify({x402Version:2,scheme:"exact",network:"base",payload:{signature,authorization:{from,to,value,validAfter,validBefore,nonce}}}))>" \ -d '{ "contacts": { "first_name": "Ada", "last_name": "Lovelace", "org_name": "Analytical Engines Ltd", "email": "ada@example.com", "phone": "+1.5555551234", "address1": "123 Main St", "city": "London", "state
