Fair use

Your monthly request allowance is visible before signup and in Account. A request means a server-admitted document-operation POST or MCP POST (including MCP tool discovery), including an operation that later fails document validation. It does not mean a token, a calculation line, CPU time or hours worked. Background live-connection polling, static pages, account management and diagnostics do not count. The month resets at 00:00 UTC on the first day of each calendar month.

When the allowance is reached, further counted operations are temporarily refused. We do not charge overage fees. Your document remains in the open tab; document download from a signed-in tab is exempt from this allowance. Contact support@waicalc.com to discuss an increase. Administrators can adjust limits or grant access; changes are audited.

No credential sharing, abusive automated traffic, interference with other users or attempts to bypass access controls. Login protection, document-size, complexity and execution-deadline limits still apply. Normal engineering calls have no per-minute or concurrency throttle. Access may be suspended for abuse; contact support to query or resolve a restriction. Fair-use counters contain no document content.
