[IPFS] Create Metadata on IPFS

This API allows you to create a Metadata file needed by NFT, on-chain records or other purposed, store it on the IPFS network through the Numbers Gateway (https://ipfs-pin.numbersprotocol.io/ipfs/) and keep it permanently stored. t requires either a fileURL or a file object along with a valid Capture Token for authorization. If you do not already have a Capture Token yet, please follow the instruction provided to create one.

The Numbers API charges you only for the files you pin, making it a cost-effective solution. Payments are taken every 30 days from your Capture Account's Asset Wallet and must be made in Credits or NUM. To avoid having your files unpinned, it's important to keep your wallet topped up and have sufficient funds. If a payment fails, you will receive an email notification and have 10 days to deposit more funds.

Payment for services is processed using NUM; if you want to know how much it costs in USD, you can check CoinGecko or CoinMarketCap.

Cost: 0.01 NUM + Gas (~0.004 NUM per transaction) per file per month. No Gas is required if paid with Credits.
