What API Developer Toolkit helps you do

API Developer Toolkit is a workflow page for inspecting pasted API requests and responses without switching between multiple separate developer tools.

Paste a raw request, cURL-style snippet, header block, or response body to detect JSON, extract headers, inspect JWT tokens, decode URL content, decode Base64 candidates, and generate common hashes.

The standalone tools remain available for focused work, while this toolkit acts like a lightweight Postman-style analysis page.

Examples, Sharing, And Export

Local only

Examples, shareable URLs, and the last 10 history entries stay in this browser only. No account is required.

Frequently asked questions

Does this replace the standalone developer tools?

No. The raw tools still exist. This toolkit simply combines them into one API workflow page.

What can I paste into the toolkit?

You can paste raw HTTP requests, request headers, API responses, JSON payloads, bearer tokens, Basic authorization headers, and mixed debugging snippets.

Does this send my request anywhere?

No live request is made from this toolkit. It analyzes the pasted content locally on the server side and returns the extracted developer-friendly views.
