HTTP Header Parser

Headers copied from a gateway, DevTools, or cURL are hard to scan. Paste them to split Content-Type, Authorization, Cache-Control, User-Agent, and Cookie — an HTTP Header Analyzer that stays on your machine.

What it is for

Break down HTTP headers locally so you can see media type, cache policy, auth scheme, UA, and cookies without uploading the message.

How to use

Paste raw headers, a full HTTP message, or a cURL command with -H flags.
Read the breakdown for Content-Type, Authorization, Cache-Control, User-Agent, and Cookie.
Copy JSON if you need the map; continue in the API debugger or JWT tool when relevant.

FAQ

Are Authorization and Cookie uploaded?

No. Parsing runs in the browser. Tokens never leave your machine.

Is this the same as the API debugger?

This page only analyzes headers you already have. Use the API debugger to send a request.
