ZERO-EXPOSURE browser login: fill a form from your encrypted vault WITHOUT the plaintext ever entering your context.
ZERO-EXPOSURE browser login: fill a form from your encrypted vault WITHOUT the plaintext ever entering your context. vault_fields maps each form @eN ref to a vault entry (or 'entry:field' for a multi-field entry), e.g. {'@e3':'github:username','@e4':'github:password'}. The gateway verifies you own the browser session, decrypts server-side, fills, and returns only {ok,url}. Requires your secret (Bearer).
Metered access — free-key quota or x402 pay-per-call (USDC on Base). Details at /pricing.
