Fixing Anthropic API Key Rate Limit Errors for Claude

Swagatam M. · 2025-08-18T12:56:27.836Z

Hey team! I have been seeing an error "The rate limits associated with this Anthropic API key are insufficient for this field" while using my own API Key while running Claude. Even after adding more amount in my Anthropic account and increasing my usage Tier, I still see this error. How do I fix this?

This error occurs due to API tier limits with Anthropic. Even after upgrading your tier and adding funds, you may need to process data in smaller batches. Try processing around 50 rows at a time instead of larger batches. You can check your current rate limits at Anthropic API settings and review the rate limits documentation for detailed information. Clay implements rate limits for system stability, and recent updates to Claude Sonnet 3.7 have doubled estimated token usage per run, which can trigger these limits more frequently.

I can see you've shared an attachment, but I'm unable to view image attachments directly. However, based on your previous message about the Anthropic API rate limit error, here are additional steps to try: Wait for tier upgrade processing: After upgrading your Anthropic tier and adding funds, there may be a delay before the new limits take effect. Check your current limits: Visit your Anthropic API settings to confirm your new tier is active and view your current rate limits. Consider Clay's recent changes: Recent updates to Claude Sonnet 3.7 have doubled estimated token usage per run, which can trigger rate limits more frequently even with upgraded tiers. If you could describe what's shown in your attachment or copy any error text, I can provide more specific troubleshooting steps.

Hi Swagatam, Thanks for reaching out to support. Do you use this API key on multiple accounts? If so, you may be running into your rate limitation even though you've expanded your tier and subscription.

Hi Nicole G. No, I've created this API key just to use for my Clay account and it is not being used anywhere else

Got it, thanks for the clarifictaiton, just wanted to let you know You need Tier 4 or higher with your Anthropic account to connect your API key to Clay. If you're currently on Tier 2, you'll need to contact Anthropic sales to upgrade your account and request at least 450,000 TPM to ensure full compatibility with Clay's ClayAgent functionality.

Oh my god. So, I have to spend $400 and move to Tier 4 before I can start using my own API key?

Hello Swagatam! Thanks for reaching out! Unfortunately those are the current limitations. You can also consider using Clay credits for other alternatives (OpenAI or Gemini) if this is not the best option for you right now.
