Authentication

EIP-191 wallet-signed auth token signature discovered Get key ↗

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.

x402 USDC payment authorization two_step discovered Get key ↗

PAYMENT-SIGNATURE: <credential>

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.
