Frequently asked questions

What errors can the JSON classifier detect?

JSON syntax errors, data type mismatches, missing required fields, auth/permission errors, rate limits, 404s and server errors — classified with a probability distribution in about 0.1 seconds.

Do I need to format my JSON before pasting?

No. Paste the raw payload or the raw error log as-is; the classifier works on malformed JSON and stack traces alike.

Does it tell me where to fix the error?

Yes. Besides classifying the error type and severity, it points to where to look first: input validation, schema definition, client/server code, configuration, or a dependency.
