If you already have a crypto wallet, you can use it to authenticate with Hober directly. No email, no password, no account creation. This uses CAIP-122, the same "Sign-In With X" standard used by dApps across Solana and EVM chains.

Wallet auth is ideal for web apps where users already have a wallet connected (like a DeFi dashboard or an agent management portal). For server-to-server calls, use an API key instead. For autonomous agents, consider x402 which requires no authentication at all.

When to Use Which Auth Method

SIWX Flow

# Step 1: Get a challenge
curl "https://api.hober.dev/api/siwx/challenge?wallet=YOUR_WALLET"

# Response: { "message": "api.hober.dev wants you to sign in...", "nonce": "abc123", "issuedAt": "..." }

# Step 2: Sign the message with your wallet, then create session
curl -X POST https://api.hober.dev/api/siwx/session \
  -H "Content-Type: application/json" \
  -d '{
    "message": "THE_CHALLENGE_MESSAGE",
    "signature": "BASE58_SIGNATURE",
    "walletAddress": "YOUR_WALLET"
  }'

# Response: { "token": "eyJhbG...", "developerId": "...", "walletAddress": "YOUR_WALLET" }
