Just sharing a quick win in here for anyone facing the same issue. We've been trying to make use of the Claude/Anthropic API key in Clay for a while but you need to be on Tier 4 or above to get it running. Rather than waiting for our usage to take us from tier 1 to tier 4 I just asked the Anthropic sales team if they'd upgrade us to tier 4 and they said yes within 24 hours. Definitely work asking if you want to use Claude at higher volumes.
