获取兑换价格#
通过 DEX 聚合器获取最优报价。
请求地址#
GET https://web3.okx.com/api/v6/dex/aggregator/quote
请求参数#
| 参数 | 类型 | 必传 | 描述 |
|---|---|---|---|
| chainIndex | String | 是 | 链的唯一标识。 如 1: Ethereum，更多可查看这里。 |
| amount | String | 是 | 交易数量。 如果 swapMode 为 exactIn，代表卖出币种数量如果 swapMode 为 exactOut，代表买入币种数量。(数量需包含精度，如兑换 1.00 USDT 需输入 1000000，兑换 1.00 DAI 需输入 1000000000000000000)，币种精度可通过币种列表取得。 |
| swapMode | String | 是 | 交易模式。可选值为：exactIn 或 exactOut。默认值为： exactIn。当设为 exactOut 时，适用于需要获取确切输出金额的使用场景。注意： 1. ExactOut 功能目前仅支持 Ethereum、Base、BSC、Arbitrum 链。 2. ExactOut 功能目前仅支持 Uni v2 和 v3 协议。 3. 在此模式下，滑点设置作用于输入代币。 |
| fromTokenAddress | String | 是 | 卖出币种合约地址 (如0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee) |
| toTokenAddress | String | 是 | 买入币种合约地址 (如0xa892e1fef8b31acc44ce78e7db0a2dc610f92d00) |
| dexIds | String | 否 | 限定询价的流动性池 dexId , 多个组合按 , 分隔 (如 1,50,180 ，更多可查看流动性列表) |
| directRoute | Boolean | 否 | 默认设置为 false。启用后，将限制路由仅使用单一流动性池。当前，该功能仅适用于 Solana 兑换。 |
| priceImpactProtectionPercent | String | 否 | (可选，默认值为 90%) 允许的价格影响百分比 (介于 0 和 100 之间)。 当用户设置了 priceImpactProtectionPercent 后，如果估算的价格影响超过了指定的百分比，将会返回一个错误。例如，如果 priceImpactProtectionPercent = 25，任何价格影响高于 25% 的报价都将返回错误。 这是一个可选开启的功能，默认值为 90。当百分比被设置为 100 时，此功能将被禁用，也就是说，每一笔交易都会被允许通过。 注意：当我们无法计算价格影响时，我们会返回 null，并且价格影响保护也会被禁用。 |
| feePercent | String | 否 | 发送到分佣地址的询价或者目标币种数量百分比。最小百分比 > 0， Solana 链 最大百分比：10。 其他链最大百分比：3最多支持小数点后 9 位，系统将自动忽略超出的部分。 |
响应参数#
| 参数 | 类型 | 描述 |
|---|---|---|
| chainIndex | String | 链的唯一标识。 |
| dexRouterList | Array | 询价路径数据集合 |
| fromTokenAmount | String | 询价币种的兑换数量 (如500000000000000000000009) |
| toTokenAmount | String | 目标币种的兑换数量 (如168611907733361) |
| tradeFee | String | 询价路径预估消耗的网络费用 (USD 计价) |
| estimateGasFee | String | 预估消耗的 gas，各个链的最小单位返回，例如 wei |
| router | String | 币种兑换的一条路径 |
| dexProtocol | Array | 兑换路径中执行的 DEX 协议 (如Verse) |
| percent | String | 一条路径中单一 DEX 协议的兑换资产占所有 DEX 协议百分比 (如100) |
| dexName | String | DEX 协议名称 |
| fromToken | Object | 询价币种信息 |
| tokenContractAddress | String | 币种合约地址 (如0xa892e1fef8b31acc44ce78e7db0a2dc610f92d00) |
| tokenSymbol | String | 币种简称 (如WETH) |
| tokenUnitPrice | String | 该接口返回的币种单价是一个结合了链上、交易所以及其他第三方来源数据的综合美元价格。注：此价格仅为推荐价格，在一些特殊情况中，币种单价可能为 null |
| decimal | String | 币种精度定义了单个的该币种可以被分成多少份的最小单位。例如，如果一个币种的精度是 8，则表示单个的这种代币可以被分成 100,000,000 份的最小单位。注意：该参数仅供参考，币种精度会随着合约拥有者的设置改变等原因发生变化。 |
| isHoneyPot | Boolean | 代币是否为貔貅币。 是：true 否：false |
| taxRate | String | 代币卖出税率，适用于可设定税费机制的代币（如SafeMoon、SPL2022代币）。普通代币无税费时返回 0。取值为 最小：0 最大：1，0.01表示1%。 |
| toToken | Object | 路径中目标币种信息 |
| tokenContractAddress | String | 币种合约地址 (如0xa892e1fef8b31acc44ce78e7db0a2dc610f92d00) |
| tokenSymbol | String | 币种简称 (如WETH) |
| tokenUnitPrice | String | 该接口返回的币种单价是一个基于链上的实时美元价格。注：此价格仅为推荐价格，在一些特殊情况中，币种单价可能为 null |
| decimal | String | 币种精度定义了单个的该币种可以被分成多少份的最小单位。例如，如果一个币种的精度是 8，则表示单个的这种代币可以被分成 100,000,000 份的最小单位。注意：该参数仅供参考，币种精度会随着合约拥有者的设置改变等原因发生变化。 |
| isHoneyPot | Boolean | 代币是否为貔貅币。 是：true 否：false |
| taxRate | String | 代币买入税率，适用于可设定税费机制的代币（如SafeMoon、SPL2022代币）。普通代币无税费时返回 0。取值为 最小：0 最大：1，0.01表示1%。 |
| quoteCompareList | Array | 询价路径对比列表 |
| dexName | String | 询价路径 DEX 名称 |
| dexLogo | String | DEX 协议名称 |
| tradeFee | String | 询价路径预估消耗的网络费用 (USD 计价) |
| amountOut | String | 询价路径的接收数量 |
| priceImpactPercent | String | Percentage = (接收价值 – 支付价值) / 支付价值。因为当前兑换数量影响了流动性池深度，导致产生了价值差额。若接收价值大于支付价值，Percentage 有可能是正数。 |
