The docs reference an account 'balance' (/docs/overview/authentication/: 'Authentication success does not guarantee model access, remaining account balance, or available capacity') but publish no pricing, free-tier, or top-up page, so billing policy could not be confirmed from public sources — treat this entry's `no-free-tier` as the conservative default in the absence of any documented free allocation, not a confirmed vendor policy",
