I realize the company has built its product targeting what seems like a mainnet solution for 10k PFPs where all of the tokens are generated at once. So the request for a sandbox with this in mind does not make sense. I am working on a project that incrementally mints tokens over time. And in this scenario I was using the classic solution to upload an image and the metadata file to IPFS vis nft.storage one at a time. Therefore, in looking at the new product I was hoping to due some testing on incremental token uploads, one at a time. To do this, I wanted to test the http API to make sure that I was crafting the API call correctly. I am now using the Pinata APIs to store the image and metadata files, then I wanted to persistently store the just minted token id with the metatdata CID to ntf.storage. I am testing all this on the Base Sepolia testnet, hence the inquiry into testnet support.

Again, this request doesn't make sense if the primary product is intended for mainnet token launches following the 10k PFP projects. I, however, am looking to use the nft.storage API to incrementally store minted NFTs as customers create them, in which case I would like to test the product against our testnet application, rather than against our mainnet application.
