agentdomainsearch.com
Agent Domain Search is a domain registration and DNS management service designed for programmatic use. It lets users check availability, register and renew domains, and manage DNS using Ethereum wallet signatures and USDC payments on Base.
agentdomainsearch.com exposes a JSON HTTP API with an OpenAPI spec plus a public MCP endpoint; the API mixes free public reads with wallet-signature auth for management operations and x402 USDC payment authorization for registration/renewal.

Use your Ethereum wallet to sign the message agentdomainsearch.com:<unix-timestamp> with EIP-191 personal_sign, then build the token as <timestamp>.<130-hex-char-signature> with the 0x prefix stripped from the signature. The docs show JavaScript and Python examples in API Documentation. Tokens are valid for 5 minutes. There is no account or API key issuance flow; your wallet is your identity.
Call a paid endpoint first; it returns 402 Payment Required with x402 payment details. Then sign the EIP-3009 payment authorization with your wallet, base64-encode the x402 payload, and retry with the PAYMENT-SIGNATURE header as shown in llms.txt. Payment details are described in the API Documentation and the x402 manifest.
