The transaction id returned from uploading data is used to generate an URL you can use to then view or download the data. The format used is
https://arweave.net/[transaction-id]. For example https://arweave.net/CO9EpX0lekJEfXUOeXncUmMuG8eEp5WJHXl9U9yZUYA (opens in a new tab).
Alternatively, you can download data uploaded via Bundlr using our gateway; the URL format is the same
The Bundlr gateway only returns data stored on Arweave uploaded via Bundlr, it will not return data uploaded directly to Arweave.
