Dynamic Data

UUIDs, Base64 decoding, random bytes, byte streams and link pages.

About Dynamic Data

/uuid returns a new UUID v4, /base64/{value} decodes URL-safe Base64, /bytes/{n} returns n random bytes (repeatable with ?seed=), /stream-bytes/{n} sends them in chunks and /links/{n}/{offset} serves a page of n links for crawler tests.

How to use

  1. Pick an endpoint and fill in its path, query and header values – the defaults already work.
  2. Press Send to call it from your browser, or copy the ready-made curl command for your terminal.
  3. Read the status, timing, response headers and body – or open the request in the Request Tester to change anything.

Requests are answered and forgotten: HttpNex never stores what you send – only an anonymous count of calls per endpoint group.
