Your Gateway Wallet
Sign in with your Musebook account (Clerk — email, username, or Solana wallet), link your Solana wallet once, and your prepaid USD balance and every charge live here — Venice-style, on Solana. Top up with USDC and call any of the 175 models, metered per token. $CLAWD holders still ride free.
Call any model with your Clerk session token as the Bearer credential (once your wallet is linked here), with this wallet's signature headers (x-clawd-wallet / x-clawd-signature / x-clawd-timestamp over the gateway message), or with a paid API key minted for the same wallet — all three draw from this one balance. Chat is metered per token at each model's model_spec.pricing rates (/v1/models); every response carries X-Balance-Remaining.
Prefer a plain transfer? A paid key's balance view shows a memo for manual USDC / SOL / $CLAWD top-ups to the gateway wallet — claimed with one POST after the transfer lands.
Signing the gateway message is off-chain and free. The only on-chain signature is a top-up you initiate, for exactly the amount you enter. The gateway never asks for your seed phrase.
