Every dashboard, wallet, and trading bot depends on it.<\/p>\n<p>But &#8220;DeFi API&#8221; is a loose label. It covers very different tools. Some APIs return protocol metrics like total value locked. Others read a single wallet&#8217;s DeFi positions. A few execute swaps directly on-chain. One layer just connects you to the blockchain itself.<\/p>\n<p>Choosing the wrong type costs weeks of integration work.

For protocol-level TVL and yields, DeFiLlama is the free standard. For on-chain swaps, 1inch leads.<\/div>\n<\/div>\n<h2>What Is a DeFi API?<\/h2>\n<p>A DeFi API is an interface for decentralized finance data and actions. It lets your code read on-chain information without running your own infrastructure. It can also help your app execute trades. New to the space? Our <a href=\"https:\/\/coinstats.app\/blog\/what-is-crypto-blockchain-api-understanding-crypto-api-a-beginners-guide\/\">beginner&#8217;s guide to crypto APIs<\/a> covers the fundamentals first.<\/p>\n<p>The label spans four distinct categories. Knowing them is half the decision when picking the <strong>best DeFi APIs<\/strong> for a project.<\/p>\n<p>The first category is market and protocol data. This covers total value locked, yields, fees, and stablecoin supply. The second is wallet and position data. This reads what a single address holds and where it is deployed. The third is swap and execution. This routes trades across decentralized exchanges. The fourth is node and RPC infrastructure. This is raw access to the chain itself.<\/p>\n<p>One distinction matters more than any other here. It separates two things that sound alike.<\/p>\n<div style=\"display:grid;grid-template-columns:1fr 1fr;gap:16px;margin:24px 0 28px 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',sans-serif;\">\n<div style=\"background:#FFF9F5;border:2px solid #F355BD;border-radius:14px;padding:22px;\">\n<div style=\"font-size:12px;font-weight:800;letter-spacing:1px;text-transform:uppercase;color:#F355BD;margin-bottom:12px;\">Token balances<\/div>\n<div style=\"font-size:16px;font-weight:700;color:#0E0E10;margin-bottom:10px;\">What a wallet holds<\/div>\n<div style=\"font-size:14px;color:#1F2024;line-height:1.65;\">A crypto token balance API returns native coins and tokens sitting in an address.

It detects per-wallet DeFi positions across protocols. That includes staking, lending, and liquidity pool stakes. It does this from a single wallet address.<\/p>\n<p>The coverage is broad. The API supports 120+ blockchains through one unified format. CoinStats API also tracks 100,000+ coins and 200+ exchanges. The same data powers the CoinStats app, used by 1M people each month.<\/p>\n<p>The response format stays identical across chains. Your code handles Solana the same way it handles Ethereum. Position detection spans more than 10,000 DeFi protocols. Portfolio analytics sit on top of the raw data.<\/p>\n<p>AI agents can reach all of this through CoinStats MCP Server. It exposes wallet, DeFi, and portfolio data through natural language. Most node and market-data APIs do not surface that layer.<\/p>\n<p>This is not a node provider.

A crypto wallet DeFi positions API returns funds deployed into protocols. It reads staking, lending, and liquidity pool stakes for an address. Balances alone miss all of that. For the wider wallet API landscape \u2014 not just DeFi positions \u2014 see our <a href=\"https:\/\/coinstats.app\/blog\/best-crypto-wallet-apis\/\">best crypto wallet APIs<\/a> roundup.<\/p>\n<p>Among the five, CoinStats Wallet API is built for this job. It detects positions per wallet across chains. The sections below show how that works on each major network. For the broader picture, see our <a href=\"https:\/\/coinstats.app\/blog\/best-multichain-crypto-portfolio-apis\/\">best multichain crypto portfolio APIs<\/a> guide.<\/p>\n<h3>EVM Wallet DeFi Positions API<\/h3>\n<p>EVM chains share one address format and token standard. That makes them a natural group. An <a href=\"https:\/\/coinstats.app\/api-docs\/wallet\/ethereum-evm\/\">EVM wallet DeFi positions API<\/a> reads holdings and deployed funds across them at once. For the EVM foundation in plain English, our <a href=\"https:\/\/coinstats.app\/blog\/whats-is-ethereum-api\/\">Ethereum API explainer<\/a> goes deeper. CoinStats covers the major EVM networks \u2014 Polygon, BNB Smart Chain, Arbitrum, Optimism, Base, and Avalanche \u2014 and one EVM token balance API call returns holdings per address. The same query surfaces positions staked or lent across protocols.<\/p>\n<h3>Crypto Wallet DeFi Positions API<\/h3>\n<p>EVM and Solana cover most of the volume. The long tail of crypto runs on dozens of other chains. A crypto wallet DeFi positions API has to handle them all without forcing a separate integration per network. <a href=\"https:\/\/coinstats.app\/api-docs\/wallet\/other-chains\/\">CoinStats Wallet API<\/a> supports 120+ blockchains through one unified format \u2014 including Cardano, Tron, Cosmos, Polkadot, Near, Algorand, Ripple, Hedera, Litecoin, Dogecoin, Stellar, and Bitcoin Cash, plus Layer 2 networks like StarkNet, zkSync Era, Polygon zkEVM, and Immutable X. The same endpoint format works across every chain, so adding a new network is one API call, not a new integration. For HD wallet tracking on Bitcoin specifically, our <a href=\"https:\/\/coinstats.app\/blog\/best-bitcoin-xpub-apis-in-2026-hd-wallet-tracking-compared\/\">best Bitcoin xPub APIs<\/a> comparison covers that niche in depth.<\/p>\n<h3>Solana Wallet DeFi Positions API<\/h3>\n<p>Solana uses a different account model from EVM chains. Its tokens and programs work their own way. A <a href=\"https:\/\/coinstats.app\/api-docs\/wallet\/solana\/\">Solana wallet DeFi positions API<\/a> has to handle that natively. CoinStats Solana API reads SPL token balances for an address and surfaces Solana DeFi positions in the same response. A Solana token positions API call returns both holdings and deployed funds \u2014 no separate Solana-only integration required.<\/p>\n<h2>Comparing the Top 5 DeFi APIs<\/h2>\n<p>The table sets the five side by side. Note that they sit in different categories. The right pick depends on the job, not on one winning row. For the wider market beyond DeFi, our <a href=\"https:\/\/coinstats.app\/blog\/top-5-best-crypto-data-apis\/\">best crypto data APIs<\/a> roundup is the next read.
