Logs & Debug Tools
API Response Debugger
Inspect a captured API response without contacting its URL or sending its contents elsewhere.
Inputs and files stay in this browser tab. These tools do not upload, log or save your data. Clear the workspace when finished.
How to use API Response Debugger
Enter the status, paste response headers and body, then select Inspect response. Choose Auto, JSON, XML or Text. Review validation and diagnostic signals; copy the formatted body or minified JSON when available.
Limits and interpretation
A response snapshot cannot prove CORS configuration, reproduce requests or diagnose every failure. XML DTD/entities are rejected. JSON uses JavaScript numeric precision and duplicate-key rules; unsafe integers disable formatting, and original input stays visible. Header values and HTML are rendered only as text, never executed or fetched.
Is my input sent to a server?
No. Parsing, filtering and validation run locally. Only an explicit copy or download action exports your results. Closing this page clears its working input.
