Provides quote of a Logic, depending on the chain and protocol. See Networks & Protocols.

const getQuote = async (chainId, protocol, logicId, logicParams) => {
    const result = await client.post(`/v1/protocols/${chainId}/${protocol}/${logicId}/quote`, {
        body: logicParams,
    });
    return result.data;
}

const chainId = 1;
const protocol = "uniswap-v3";
const logicId = "swap-token";
const logicParams = {
    input: {
        token: USDC,
        amount: '1000'
    },
    tokenOut: WBTC,
    slippage: 100, // 1%
};

const swapQuote = await getQuote(chainId, protocol, logicId, logicParams);

Quote is used in fields of Logic data. It can be used after building Logic according to the following format:

const swapLogic = {
    rid: `${protocol}:${logicId}`,
    fields: swapQuote,
}

Logic Params (default)

// aave-v2: deposit, withdraw
// aave-v3: supply, withdraw
// uniswap-v3: swap-token (exact in)
// utility: wrapped-native-token
{
    input: {
        token: inputToken,
        amount: inputAmount
    },
    tokenOut: tokenOut,
    slippage: 100, // 1%
}

// uniswap-v3: swap-token (exact out)
{
    tokenIn: tokenIn,
    output: {
        token: inputToken,
        amount: inputAmount
    },
    slippage: 100, // 1%
}

The result contains a list of chains that looks the following:

{
    "tradeType": "exactOut",
    "input": {
        "token": {
            "chainId": 1,

            "decimals": 8,

            "name": "Wrapped BTC"

Compound Logics Params

// compound-v3: supply-base, withdraw-base
{
    marketId: marketId
    input: {
        token: inputToken,
        amount: inputAmount
    },
    tokenOut: tokenOut,
}

// compound-v3: repay
{
    marketId: marketId

    tokenIn: tokenIn,
}

// compound-v3: claim
{
    marketId: marketId
    borrower: USER_ADDRESS,
