The AI Agent will pause until your messages reset at the start of next month. You can upgrade to Pro or Business for unlimited messages.

Does the Free plan include API access?

Yes. All plans include API access with unlimited API keys. The Free plan has a rate limit of 100 requests per minute. Pro allows 1,000 req/min, and Business has no rate limit.
