Takes a base64 file up to 25 MB and stores it for as long as you say, at most seven days. You get a download URL carrying a 32-byte token; whoever holds the link can fetch the file once or up to a limit you set, with no payment and no account. Price is 0.004 USDC per started megabyte, quoted before payment from the size you declare. Actions: store, status, delete.
