## About

## What it does
Identifier Batch Generator creates batches of UUIDs, ULIDs, NanoIDs, hex strings, or short tokens from a single request. Send a `format`, plus optional `size` and `count`, and get back a structured JSON response suitable for fixtures, seed data, test records, or client-side temporary IDs.

Use `count` to control how many identifiers you want, from 1 to 1000. Use `size` when generating `nanoid`, `hex`, or `token` values to set the length; it defaults to 21. The `format` field accepts `uuid4`, `uuid7`, `ulid`, `nanoid`, `hex`, or `token`, so you can match the identifier style your system already expects.

This is a good fit for backend jobs, test setup scripts, and internal tooling where you need many unique values without writing your own generator. Keep your integration simple: choose the identifier type, set the batch size, and consume the JSON response in the same workflow that needs the IDs.

## Usage

Authenticate with an ApyHub API key in the `apy-token` header.
