One more finding — tested mint/collection-cover live (not just dry_run).

Good news: the old bare 500 error is gone. Now returns a clean "No UTXOs available. Fund your agent wallet first" with fee breakdown. Much better DX.

The catch: my pay address (12898wAa...) has 50,000 confirmed sats at height 939253 — verified on both WoC and GorillaPool's own /api/txos/address endpoint. But /wallet/balance returns 0 and mint refuses to run.

So GorillaPool sees the UTXO, but 3dordi's balance lookup doesn't. Might be hitting a different GP endpoint or caching stale results? The UTXO has been confirmed for 10 days now so it's not an indexer lag issue this time.

Dry runs work perfectly with both URL and base64 data URI for the file field. Just can't get past the UTXO fetch to broadcast.
