This is a very basic no-frills scraper to retrieve the metadata and digital assets from all tokens minted on hicetnunc.xyz. I share this as a starting point for people who want to experiment with building alternative views on the works created on the platform or preserve the data. Feel free to improve upon this or add additional features.

There is now an improved version by Marcel Schwittlick that adds parallel downloads which should speed up the process quite a bit:

This will not work anymore with some of the latest changes to the api
I was just looking at your script, it does not work as you noted, is there a reason though why it only pulls 10 last items? am I missing something? I am referring to this bit
url = "https://better-call.dev/v1/contract/mainnet/KT1RJ6PbjHpwc3M5rw5s2Nbmefwbuwbdxton/tokens"
Did you miss my comment right above yours? The API was changed a few weeks after I published this and this approach does not work anymore.

On MacOS you might need to change
ipfsApi
to lowercaseipfsapi
And in order to run
Please note that this is not recommended way of running it and one should probably use virtual environment like
pyenv
to manage dependencies.
