Understanding Anthropic API Tier Requirements for Sonnet 4.0

·

Hi, what tier do I need to be in Anthropic to use Sonnet 4.0 in Clay? I'm Tier 4 now, but get the message "The rate limits associated with this Anthropic API key are insufficient for this field. Search "Anthropic Increase Limits" or visit https://docs.anthropic.com/en/api/rate-limits to increase your API key limits."

For ClayGent Web Research with Anthropic, you need Tier 4 or higher (≥400, 000 TPM). The error message suggests that while you're in Tier 4, your specific API key might not have sufficient rate limits for using Sonnet 4.0. You should check your current limits at Anthropic's API settings page and potentially request an increase.

Hey! If you’re seeing that message, it usually means your current tier doesn’t meet the token limits required by Clay. To use Sonnet 4.0 reliably, your Anthropic key should support around 400,000–450,000 tokens per min. If you were recently upgraded, it may take a bit for the new limits to apply. You can check your exact quota or request an increase here: Anthropic Rate Limits Let me know if you have more questions.

Hi Bo (., thanks for the reply. Out of curiosity, why does Clay set the token limit so high? For example, I'm tier 5 with Open AI's API (with a maximum spend of $200k per month)- yet I can't access o3 in Clay. To go any higher, I need to contact their sales team and negotiate a custom plan.

It’s set high to avoid losing context—if the token limit is too low, the model can cut off important data, which can cause the enrichment to fail, return nothing, and lead to wasted credits and missing results. Let me know if you have more questions.
