What this tool does not do / Limits
This tool only reads the JSON you paste. It does not fetch a live discovery document and does not verify that the endpoints work.
Frequently asked questions
Does this fetch the live document?
No. You paste the document; this page never fetches it.
What if JSON parsing fails?
The tool reports that the text is not valid JSON, so you can paste the full document again.
