No designer. No developer. No animator. Just me and a few AI tools. It was our new <a href=\"https:\/\/coinstats.app\/api\/ethereum\/\">CoinStats Ethereum API<\/a> page, live that night.<\/p>\n\n<p>Here is what hit me after. The page was the easy part. AI can spin up a clean interface in an afternoon. The data behind it is the hard part.<\/p>\n\n<p>So I did the homework. I researched every Ethereum API I could find. Then I turned it into this guide. If you build on Ethereum, this should save you time.<\/p>\n\n<p>Below are my seven Ethereum API picks for 2026. CoinStats API is first, and I will be honest about why. I will also be fair to the rest.<\/p>\n\n<div style=\"background:#1A1B2E;border-radius:14px;padding:22px 26px;margin:24px 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',sans-serif;\"><div style=\"font-size:12px;font-weight:800;letter-spacing:1.4px;text-transform:uppercase;color:#FFFFFF;margin-bottom:10px;\">Our bias, up front<\/div><div style=\"font-size:15.5px;color:#FFFFFF;line-height:1.7;\">We make CoinStats API, so yes, we are biased.

New to this? Start with our primer on <a href=\"https:\/\/coinstats.app\/blog\/whats-is-ethereum-api\/\">what an Ethereum API is<\/a>.<\/p>\n\n<p>One is a node or RPC provider. It speaks raw JSON-RPC to an Ethereum node. You get blocks, calls, and gas, but no structure. The other is a data API. It returns clean, indexed answers. Balances, tokens, transfers, DeFi, prices.<\/p>\n\n<p>This guide focuses on the second kind. Most apps do not need a raw node. They need readable data, fast. The market has moved this way too.<\/p>\n\n<p>Ethereum is also no longer one chain. Users hold assets across Base, Arbitrum, Optimism, and Polygon. A good Ethereum API treats those EVM chains as one surface. You should not query each chain alone.<\/p>\n\n<svg viewBox=\"0 0 700 250\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" style=\"width:100%;height:auto;display:block;margin:24px 0;\" role=\"img\" aria-label=\"One call returns the whole Ethereum picture\">\n  <rect x=\"0\" y=\"0\" width=\"700\" height=\"250\" rx=\"14\" fill=\"#1A1B2E\"\/>\n  <defs>\n    <linearGradient id=\"apiPill\" x1=\"0\" y1=\"0\" x2=\"1\" y2=\"0\">\n      <stop offset=\"0\" stop-color=\"#C238E8\"\/>\n      <stop offset=\"1\" stop-color=\"#FF4F7C\"\/>\n    <\/linearGradient>\n    <marker id=\"ar\" markerWidth=\"8\" markerHeight=\"8\" refX=\"6\" refY=\"4\" orient=\"auto\"><path d=\"M0,0 L8,4 L0,8 Z\" fill=\"#A8A4B8\"\/><\/marker>\n  <\/defs>\n  <text x=\"26\" y=\"36\" fill=\"#FFFFFF\" font-family=\"-apple-system,sans-serif\" font-size=\"12\" font-weight=\"700\" letter-spacing=\"1.6\">ONE CALL, THE WHOLE ETHEREUM PICTURE<\/text>\n  <rect x=\"26\" y=\"92\" width=\"150\" height=\"66\" rx=\"8\" fill=\"#FFF9F5\"\/>\n  <text x=\"101\" y=\"120\" text-anchor=\"middle\" fill=\"#1A1B2E\" font-family=\"-apple-system,sans-serif\" font-size=\"13\" font-weight=\"700\">Wallet address<\/text>\n  <text x=\"101\" y=\"140\" text-anchor=\"middle\" fill=\"#888780\" font-family=\"-apple-system,sans-serif\" font-size=\"11.5\">0xab&#8230;f29 + EVM chains<\/text>\n  <line x1=\"176\" y1=\"125\" x2=\"262\" y2=\"125\" stroke=\"#A8A4B8\" stroke-width=\"1.5\" marker-end=\"url(#ar)\"\/>\n  <rect x=\"262\" y=\"96\" width=\"176\" height=\"58\" rx=\"26\" fill=\"url(#apiPill)\"\/>\n  <text x=\"350\" y=\"130\" text-anchor=\"middle\" fill=\"#FFFFFF\" font-family=\"-apple-system,sans-serif\" font-size=\"18\" font-weight=\"800\">Ethereum API<\/text>\n  <line x1=\"438\" y1=\"125\" x2=\"524\" y2=\"125\" stroke=\"#A8A4B8\" stroke-width=\"1.5\" marker-end=\"url(#ar)\"\/>\n  <rect x=\"524\" y=\"58\" width=\"150\" height=\"30\" rx=\"8\" fill=\"#FFF9F5\"\/><text x=\"599\" y=\"78\" text-anchor=\"middle\" fill=\"#1A1B2E\" font-family=\"-apple-system,sans-serif\" font-size=\"12.5\" font-weight=\"700\">Balances + tokens<\/text>\n  <rect x=\"524\" y=\"94\" width=\"150\" height=\"30\" rx=\"8\" fill=\"#FFF9F5\"\/><text x=\"599\" y=\"114\" text-anchor=\"middle\" fill=\"#1A1B2E\" font-family=\"-apple-system,sans-serif\" font-size=\"12.5\" font-weight=\"700\">DeFi positions<\/text>\n  <rect x=\"524\" y=\"130\" width=\"150\" height=\"30\" rx=\"8\" fill=\"#FFF9F5\"\/><text x=\"599\" y=\"150\" text-anchor=\"middle\" fill=\"#1A1B2E\" font-family=\"-apple-system,sans-serif\" font-size=\"12.5\" font-weight=\"700\">Live prices<\/text>\n  <rect x=\"524\" y=\"166\" width=\"150\" height=\"30\" rx=\"8\" fill=\"#FFF9F5\"\/><text x=\"599\" y=\"186\" text-anchor=\"middle\" fill=\"#1A1B2E\" font-family=\"-apple-system,sans-serif\" font-size=\"12.5\" font-weight=\"700\">Token risk<\/text>\n  <text x=\"26\" y=\"226\" fill=\"#A8A4B8\" font-family=\"-apple-system,sans-serif\" font-size=\"12.5\">Pass one address.

Five things matter most.<\/p>\n\n<ul>\n  <li><b>Coverage.<\/b> Does it return Ethereum plus the EVM chains you need?<\/li>\n  <li><b>Data depth.<\/b> Balances and tokens, but also DeFi, history, and prices.<\/li>\n  <li><b>Free tier.<\/b> Can you build and test before you pay?<\/li>\n  <li><b>AI readiness.<\/b> Does it ship an MCP server for agents?<\/li>\n  <li><b>Docs and limits.<\/b> Clear docs, and rate limits you can model.<\/li>\n<\/ul>\n\n<p>One note on AI readiness. MCP support is spreading fast. Most providers here now ship one. So it is becoming table stakes, not a tiebreaker. The real difference is the data underneath.<\/p>\n\n<h2 id=\"table\">The 7 best Ethereum APIs at a glance<\/h2>\n\n<div

Modeling custom onchain data? The Graph lets you shape it. Need deep history across many chains? Covalent is built for that.<\/p>\n\n<p>Want real-time streams into your database? Goldsky handles that. Need AI-ready data over REST and SQL? Chainbase fits. Want broad multichain coverage from one key? Tatum works. Just need free Ethereum token data? Ethplorer is enough.<\/p>\n\n<p>Then test before you commit. Run the free tier against your real endpoints. Check the response shape, the latency, and the rate limits. A homepage logo does not prove a chain is supported. The actual response does.<\/p>\n\n<div class=\"cs-ugc-reddit\">\n  <div class=\"cs-ugc-top\">\n    <span style=\"display:inline-flex;align-items:center;justify-content:center;width:22px;height:22px;border-radius:50%;background:#1A1B2E;color:#fff;font-weight:800;font-size:13px;\">r<\/span>\n    <span class=\"cs-ugc-sub\">r\/ethdev<\/span>\n    <span>&#183; the question that keeps coming up<\/span>\n  <\/div>\n  <div class=\"cs-ugc-body\">&#8220;I just want one endpoint for a wallet&#8217;s balances, DeFi, and prices on Ethereum.

A broad community roundup.<\/a>\n<\/div>\n\n<h2 id=\"faq\">Frequently asked questions about Ethereum APIs<\/h2>\n<p>Common questions developers ask when choosing an Ethereum API.<\/p>\n\n<details class=\"cs-faq\"><summary>What is an Ethereum API?<span>+<\/span><\/summary><div class=\"a\">An Ethereum API is an HTTP endpoint that returns Ethereum data on request. You send a query. The server returns JSON. Data APIs give you clean answers like balances and prices. Node APIs give you raw JSON-RPC.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>What is the best Ethereum API?<span>+<\/span><\/summary><div class=\"a\">There is no single winner. The best one depends on your use case. CoinStats API fits wallet and portfolio apps. The Graph fits custom indexing. Covalent fits cross-chain history.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>Is there a free Ethereum API?<span>+<\/span><\/summary><div class=\"a\">Yes. Most providers here offer a free tier or trial. CoinStats API, The Graph, Tatum, and Ethplorer all have free access. Limits and rate caps vary, so check each plan.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>What is the difference between an Ethereum API and an Ethereum RPC?<span>+<\/span><\/summary><div class=\"a\">An RPC speaks raw JSON-RPC to a node. It returns blocks, calls, and gas, but no structure. A data API returns indexed answers. Balances, tokens, DeFi, and prices, ready to use.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>What is an EVM API?<span>+<\/span><\/summary><div class=\"a\">An EVM API returns data from Ethereum and EVM-compatible chains. Base, Arbitrum, Optimism, and Polygon all use the EVM. One EVM API can read them through a shared format.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>How do I get Ethereum wallet balances from an API?<span>+<\/span><\/summary><div class=\"a\">Call a wallet or token endpoint with the address. A data API like CoinStats API returns balances, tokens, and DeFi in one response. You can also read balances from a node API. But then you decode them yourself.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>Can I get Ethereum DeFi data from an API?<span>+<\/span><\/summary><div class=\"a\">Yes. Several APIs resolve DeFi positions like staking, lending, and LPs. CoinStats API returns them per wallet across chains. Covalent and Tatum also expose DeFi and protocol data.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>What is the best Ethereum API for developers?<span>+<\/span><\/summary><div class=\"a\">It depends on what you build. For aggregated wallet and market data, CoinStats API is a strong start. For real-time indexing pipelines, Goldsky fits. Test the free tier against your own endpoints first.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>Which Ethereum API works with AI agents and MCP?<span>+<\/span><\/summary><div class=\"a\">Most do, including CoinStats API, The Graph, Covalent, Tatum, Chainbase, and Goldsky. MCP is becoming a baseline feature. Focus on the data quality and coverage underneath.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>How many requests do free Ethereum APIs allow?<span>+<\/span><\/summary><div class=\"a\">It varies a lot. CoinStats API includes 20,000 credits a month. The Graph allows 100,000 free queries a month. Always model your daily call volume against the limit.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>What is the best Ethereum API for wallet and portfolio data?<span>+<\/span><\/summary><div class=\"a\">CoinStats API is built for this case. It returns balances, tokens, DeFi, and prices per wallet. It covers Ethereum and 74 EVM chains in one schema. That keeps portfolio code simple.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>Do Ethereum APIs support other EVM chains?<span>+<\/span><\/summary><div class=\"a\">Most do. Modern Ethereum APIs treat EVM chains as one surface. Base, Arbitrum, Optimism, and Polygon are usually included. Check the exact chain list before you build.<\/div><\/details>\n\n<details class=\"cs-faq\"><summary>How do I choose an Ethereum API?<span>+<\/span><\/summary><div class=\"a\">Match the API to your use case first. Then test the free tier on your real endpoints. Check coverage, data depth, latency, and rate limits. Pick the one that returns your data with the least glue code.<\/div><\/details>\n\n<div class=\"cs-cta\" style=\"margin:36px 0 16px 0;padding:36px 32px;background:linear-gradient(135deg,#F355BD 0%,#FF7E55 55%,#FF9332 100%);border-radius:14px;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',sans-serif;color:#FFFFFF;\">\n  <div style=\"font-size:22px;font-weight:800;margin-bottom:8px;\">Build on the complete Ethereum data layer<\/div>\n  <div style=\"font-size:15px;line-height:1.6;margin-bottom:20px;opacity:0.95;\">Wallet balances, DeFi, prices, and token risk across 120+ chains.
