CBROS Cardano NFT Minter

Everything you need before your first call: where to send ADA, and how much. No API key required -- call this first, before 'register'.

無需輸入參數。

Register a new API key by paying a one-time fee. Pay the registration fee (see get_server_info) from the Cardano address you want your key bound to, sending it to the operator's payment_address, then call this with that transaction's hash. The payment must already be CONFIRMED on-chain (wait ~20-30s after submitting, or check with check_payment_status). One active key per address -- registering twice with the same address fails. Each payment transaction can only be used once, for registration or for a mint, not both.

Check whether a payment transaction is confirmed on-chain yet. Poll this after paying and before calling 'register', 'mint', or trusting a payment_tx you're about to reference -- submitting a transaction does not mean it is confirmed.

Build an unsigned transaction that pays the mint fee from from_address to the operator, with change returned to from_address. You (or your human operator) sign and submit it yourself -- this server never sees or holds private keys. Entirely optional: you can send the payment with any tool of your choice and skip this.

Mint an NFT after separately paying the mint fee (see prepare_payment or pay any other way, then wait for on-chain confirmation -- check_payment_status). Pin your asset (and a thumbnail, for video) to IPFS yourself first; this server never stores files. Each payment transaction hash can only be used once -- a failed mint attempt does not consume it, retry with the same payment_tx. You are solely responsible for the content referenced by ipfs_hash.

Build a single transaction that pays the mint fee from from_address AND mints the NFT to destination_address at the same time -- no separate payment step, no payment_tx. Either both happen or neither does. The operator co-signs its own two witnesses (minting policy + its own fee-covering input) before returning the transaction -- inspect it before signing. You then add your own witness for from_address and submit: sign partially_signed_tx directly (cardano-cli 'transaction sign --tx-file <this> --signing-key-file <your key>', or a CIP-30 wallet's signTx(_, true) then merge the witness) and submit it yourself -- this server cannot sign or submit on your behalf. Pin your asset to IPFS yourself first. You are solely responsible for the content referenced by ipfs_hash.
