Floor-sweep: buy the CHEAPEST N listed ENS names in a category/collection (or matching a filter) in ONE Seaport transaction.
Use this when the user wants "the cheapest N", "sweep the floor", or "buy up to X ETH of" a cohort — rather than naming specific names (that's batch_purchase).
Pick the cohort with 'category' (a collection slug like "999-club") and/or 'q'/'charType'/'minLength'/'maxLength'. Bound the sweep with 'count' (how many) and/or 'maxBudgetEth' (total spend), plus an optional 'maxPriceEth' per-name cap. It selects cheapest-first across NameWhisper, OpenSea, and Grails, then packs them into one fulfillAvailableAdvancedOrders call (capped at 20 names — run again to continue). NFTs are delivered directly to the buyer; Seaport skips any order that sold since discovery and refunds the excess. The response reports what was swept (with marketplace + price), the total, and how many matched but fell outside the bound.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| category | string | no | Collection slug to sweep, as used by the marketplace (e.g. "999-club", "10k-club", "three-letter"). Comma-separate for multiple. Optional if q/charType/length is given. |
| q | string | no | Label text filter (substring), e.g. "punk" to sweep names containing punk. |
| charType | string | no | Restrict to a character class. "mixed" covers any label combining letters and digits; "hex" narrows to just the all-hex-digit ones (abc666, 1a2b). |
| minLength | integer | no | Minimum label length. |
| maxLength | integer | no | Maximum label length. |
| count | integer | no | How many names to sweep, cheapest-first (max 20 per tx). Defaults to 10 if no budget is given. |
| maxBudgetEth | number | no | Total ETH budget — keeps buying up the floor until adding the next cheapest would exceed this. |
| maxPriceEth | number | no | Per-name price cap — skip any listing above this so a pricey outlier just off the floor is not swept up. |
| walletAddress | string | yes | Buyer wallet address — receives all swept names. |
