Buy & Sweep

Easily add buying and sweeping into your app

Buy and sweep NFTs from any app

Reservoir make it easy to add buying and sweeping functionality directly into your product. You can show your users the best prices across all major marketplaces and execute orders through one simple interface.

  1. Get aggregated listings from major marketplaces and buy using the NFT Trading APIs or ReservoirKit
  2. Let your users buy multiple on sale NFTs across many marketplaces in one transaction. See our guide on how to Add Sweeping using the ReservoirSDK
  3. Set your own referrer fees on-top of aggregated orders to generate revenue (see Custom Fees)
  4. Automatically add missing royalty fees on-top of aggregated orders (see Normalized Royalties)

How to add buy or sweep to your app

You can add buying and sweeping to your app using the Reservoir API or Reservoir SDK.


We recommend using Reservoir SDK

Reservoir SDK includes helpers that abstract the process of iterating through steps, and returning callbacks that can be used to update your UI.

Trading API

Here is an example cURL request sweeping three tokens from the same collection. You can view execute/buy/v7 here: (

curl --request POST \
     --url \
     --header 'accept: */*' \
     --header 'content-type: application/json' \
     --header 'x-api-key: demo-api-key' \
     --data '
  "tokens": [
  "onlyPath": false,
  "currency": "0x0000000000000000000000000000000000000000",
  "normalizeRoyalties": false,
  "partial": false,
  "skipBalanceCheck": false,
  "allowInactiveOrderIds": false,
  "excludeEOA": false,
  "taker": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c000000"


Here is an example with the SDK with the same tokens. You can view buyToken from the SDK here: (

import { getClient, Execute } from "@reservoir0x/reservoir-sdk";
import { createWalletClient, http } from 'viem'


address = "0x8ba1f109551bD432803012645Ac136ddd6000000"
signer = createWalletClient({
  account: address,
  transport: http()

  items: [
    { token: "0x34d85c9cdeb23fa97cb08333b511ac86e1c4e258:61558"},
    { token: "0x34d85c9cdeb23fa97cb08333b511ac86e1c4e258:74395"},
    { token: "0x34d85c9cdeb23fa97cb08333b511ac86e1c4e258:80443"},
  onProgress: (steps: Execute['steps']) => {
