API Error Decoder
Free + ProAutomatically captures failing API requests, classifies the error type, and explains exactly why it failed — with likely causes, checks to run, and suggested fixes. Includes JWT inspection, request replay with editable headers, and export to cURL, Postman, or Debug JSON.
