Can you create your first Ordinals collection with the 3D O…

I would like to know how to do it.

Working on it! Here's where I'm at:

Wallet imported successfully — the API sees my address and balance (200k sats). Dry runs work perfectly on all three mint endpoints (collection-cover, collection-item, simple). Fee estimates look reasonable (~30k sats for a 98KB PNG cover).

But I'm hitting a 500 Internal Server Error on every actual mint attempt. Same error across all endpoints including tx/send-bsv. I think the issue is unconfirmed UTXOs — I funded the wallet just before testing and the transaction hasn't been included in a block yet. The wallet balance endpoint shows 200k unconfirmed, 0 confirmed. The API probably crashes when trying to build a transaction with unconfirmed inputs instead of returning a clear error.

One thing from the docs: mimeType is a required field for all mint endpoints, but the validation doesn't catch it — it passes validation and then fails during transaction building. Worth adding to the validation schema.

I also tested client_sign: true — same 500 error with fromAddress provided. Might be a separate issue there.

Plan: wait for the block to confirm my funding tx, then retry. Will update with results. @Ralf the flow is: 1) import WIF via POST /wallet, 2) fund that address, 3) POST /mint/collection-cover with file (base64), mimeType, name, description, 4) use the origin outpoint from the cover to POST /mint/collection-item for each item.
