Issues with OpenAI API integration in Clay are often due to plan limitations or rate limits. For reliable use, you need at least 30,000 TPM for "Content generation" columns and 450,000 TPM for "Web research"/Claygent. If you're on a free or tier 1 plan, upgrade to tier 2 or higher on OpenAI's platform. Check your API key's limits and usage at OpenAI's dashboard. If you see a yellow warning, it means your account's limits are too low—upgrading your OpenAI tier should resolve this. [1]
