How to Use AI API Error Decoder

  1. 1

    Paste the error response

    Copy the full error response from your API call — JSON, text, or HTTP response body — and paste it into the input area.

  2. 2

    Check the auto-detected provider

    The tool identifies the API provider (OpenAI, Claude, Gemini, Cohere, Mistral) from the error format and shows the specific error type and HTTP status.

  3. 3

    Read the explanation and fix

    The decoded output includes a plain-English explanation, root cause, and fix code snippets in Python and Node.js that you can copy directly into your project.

  4. 4

    Apply the retry strategy

    Follow the recommended retry strategy — whether to retry immediately, use exponential backoff, or not retry at all — with suggested delay patterns and maximum retry counts.
