With Enso API, you can retrieve detailed information about DeFi protocols, tokens, and user balances. These endpoints enable you to build data-rich applications with comprehensive DeFi protocol information.

​
Protocol Information

The Protocol API endpoints provide access to DeFi protocol data, standards, and volume metrics.

​
Get Supported Protocols

Retrieve a list of all protocols supported by Enso, including names, logos, and supported chains. API Reference: GET /v1/protocols 
import { EnsoClient } from '@ensofinance/sdk';

// Initialize the client with your API key
const enso = new EnsoClient({
  apiKey: 'YOUR_API_KEY' // Replace with your actual API key
});

// Get all supported protocols
async function getAllProtocols() {
  try {
    const protocols = await enso.getProtocolData();
    console.log('Supported protocols:', protocols);
    return protocols;
  } catch (error) {
    console.error('Error fetching protocols:', error);
    throw error;
  }
}

getAllProtocols();

​
Get Protocol Standards and Actions

Access detailed information about protocols’ supported actions and standards. This helps you understand which operations can be performed with specific protocols. API Reference: GET /v1/standards 
// Get all available standards (protocols and their actions)
async function getProtocolStandards() {
  try {
    const response = await fetch('https://api.enso.finance/api/v1/standards', {

        'Authorization': `Bearer ${enso.apiKey}`,
        'Content-Type': 'application/json'
      }
    });
    const standards = await response.json();
    console.log('Protocol standards and actions:', standards);
    return standards;
  } catch (error) {
    console.error('Error fetching standards:', error);
    throw error;
  }
}

// Get specific protocol standard
async function getProtocolStandardBySlug(slug) {
  try {
    const response = await fetch(`https://api.enso.finance/api/v1/integration/${slug}`, {
      headers: {
        'Authorization': `Bearer ${enso.apiKey}`,
        'Content-Type': 'application/json'
      }
    });
    const standard = await response.json();
    console.log(`Standard for ${slug}:`, standard);
    return standard;
  } catch (error) {
    console.error(`Error fetching standard for ${slug}:`, error);
    throw error;
  }
}

getProtocolStandards();
getProtocolStandardBySlug('aave-v3');

​
Get Protocol Volume Data

Retrieve transaction volume on a given chain. API Reference: GET /volume/{chainId}

      }
    });
    const volumeData = await response.json();
    console.log(`Volume data for chain ${chainId}:`, volumeData);
    return volumeData;
  } catch (error) {
    console.error(`Error fetching volume data for chain ${chainId}:`, error);
    throw error;
  }
}

// Get volume data for Ethereum
getChainVolume(1);

​
Position Information

The Token API delivers data about DeFi assets including pricing, composition, and yield metrics. Filter tokens by protocol, chain, underlying assets, APY, or TVL to discover specific DeFi opportunities.

​
Filter Supported Tokens

Query tokens based on various criteria like protocol, underlying assets, or token type. This helps users discover specific DeFi opportunities. API Reference: GET /v1/tokens 
import { EnsoClient } from '@ensofinance/sdk';

// Initialize the client with your API key
const enso = new EnsoClient({
  apiKey: 'YOUR_API_KEY' // Replace with your actual API key
});

// Get Aave V3 DeFi tokens on Ethereum mainnet (chainId 1) with USDT as underlying
async function getAaveV3UsdtTokensOnEthereum() {
  try {
    const tokenData = await enso.getTokenData({
      chainId: 1, // Ethereum mainnet
      protocolSlug: 'aave-v3',
      type: 'defi',
      underlyingTokens: '0xdAC17F958D2ee523a2206206994597C13D831ec7', // USDT
      includeMetadata: true
    });
    
    console.log('Aave V3 DeFi tokens with USDT as underlying on Ethereum:', tokenData.data);
    return tokenData.data;
  } catch (error) {
    console.error('Error fetching tokens:', error);
    throw error;
  }
}

getAaveV3UsdtTokensOnEthereum();

​
Get Protocol TVL and APY Data

Access yield and total value locked (TVL) information for DeFi protocols. This data is crucial for comparing investment opportunities across the DeFi landscape. API Reference: GET /v1/tokens with APY filters 
import { EnsoClient } from '@ensofinance/sdk';

// Initialize the client with your API key
const enso = new EnsoClient({
  apiKey: 'YOUR_API_KEY' // Replace with your actual API key
});

// Get tokens with APY over 5% for a specific protocol
async function getHighYieldTokensForProtocol(protocolSlug: string, minApy: number = 5) {
  try {
    const tokenData = await enso.getTokenData({
      chainId: 1,
      protocolSlug: protocolSlug,
      type: 'defi',
      apyFrom: minApy,
      includeMetadata: true
    });

getHighYieldTokensForProtocol('yearn');

​
Get Token Prices

Retrieve current token prices with confidence scores, supporting decision-making around token swaps and valuations. API Reference: GET /prices/token-price 
import { EnsoClient } from '@ensofinance/sdk';

// Initialize the client with your API key
const enso = new EnsoClient({
  apiKey: 'YOUR_API_KEY' // Replace with your actual API key
});

// Get price data for a specific token
async function getTokenPrice(chainId: number, tokenAddress: string) {
  try {
    const priceData = await enso.getPriceData({
      chainId,
      address: tokenAddress
    });
    
    console.log(`Price data for ${tokenAddress} on chain ${chainId}:`, priceData);
    return priceData;
  } catch (error) {
    console.error('Error fetching token price:', error);
    throw error;
  }
}

// Get price for WETH on Ethereum
getTokenPrice(1, '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2');
I’ll add the token information use cases with the specified layout and examples:

const aaveTokens = await ensoClient.getTokenData({
  chainId: 1,
  protocolSlug: "aave-v3",
  includeMetadata: true
});

​
Filter by Token Type and Minimum TVL

Find specific token types with a minimum TVL (Total Value Locked) threshold to focus on well-established and liquid DeFi positions. API Reference: GET /v1/tokens 
// SDK Example
const ensoClient = new EnsoClient({
  apiKey: "your-api-key"
});

const defiTokens = await ensoClient.getTokenData({

  tvl: 1000000, // $1M minimum TVL
  includeMetadata: true
});
