01 — Connect wallet
Generate your free key.

Connect a wallet to create a free developer API key. You will sign a message to verify ownership. This is not a blockchain transaction and costs no gas.

Step 1 — Review message
Generate 8k4 API key for wallet 0xYOUR_WALLET at timestamp 1773870300

The API expects an exact wallet-signed message. This preview will request the live sign-in payload from the API when you connect.
