When making API calls to Keywords AI, you may encounter errors from two sources:
  1. Keywords AI errors - Errors thrown by the Keywords AI platform itself
  2. Provider errors - Errors from the underlying LLM provider (e.g., OpenAI, Anthropic)

​
Keywords AI Exceptions

When Keywords AI encounters an error, it will throw a KeywordsAIException. The error response will include details about what went wrong.

  "error": {

    "code": "invalid_api_key"
  }
}
