Ethereum & EVM API for Token, Wallet & DeFi Data

An Ethereum API lets you read Ethereum and EVM data programmatically. With CoinStats you pass an address and get ERC-20 balances, native ETH, transaction history, DeFi positions, and token risk scores back as JSON, each priced in USD, without running a node or parsing raw chain data.

An Ethereum RPC is your gateway to a node: you read raw network state and submit transactions, and handle parsing and pricing yourself. A data API like CoinStats does that upstream and returns enriched, pre-priced data. Use an RPC to send transactions or read raw state; use CoinStats for readable, portfolio-ready data.

For wallet and portfolio data, yes. CoinStats returns ERC-20 and ETH balances, transaction history, DeFi positions, and prices for any Ethereum address through one API, with a free tier and credit-based pricing. It is a data API rather than a block explorer, so it does not host verified contract source, but for reading address balances, history, and value it is a common alternative.

No. CoinStats is a data API for reading on-chain and market data. It does not create wallets, hold keys, run RPC nodes, or submit transactions. Pair it with an RPC or wallet provider if you need those.

Alchemy is primarily RPC plus data APIs; Moralis is an EVM data API. Both offer balances, prices, and some DeFi data. CoinStats focuses on enriched, portfolio-ready output: balances pre-priced in one response, native token security via Hexens, portfolio analytics with P&L, and 120+ chains including non-EVM, in one schema. For raw node access or sending transactions, use an RPC provider.

Yes. The CoinStats MCP Server exposes wallet, DeFi, and portfolio tools, including Ethereum data, over the Model Context Protocol. It works with Claude, Cursor, Claude Code, VS Code, and N8N. The same API key works for REST and MCP.

Yes. Pass any Ethereum or EVM address and get all ERC-20 balances plus native ETH, with token metadata and live USD prices attached in one response.

Yes. Full transaction history: ERC-20 transfers, ETH movements, swaps, and contract interactions, each with timestamps, amounts, token identifiers, gas data, and USD value at the time of the transaction.

Yes. Staking, lending, LP shares, and yield positions across EVM protocols are auto-detected per wallet and resolved to USD values, with no protocol-by-protocol setup.

Yes. The Token Risks endpoint returns an overall risk score plus severity-ranked findings (honeypots, mint/blacklist controls, hidden fees, upgradeable proxies, and more) with plain-English notes, powered by Hexens' Glider engine across Ethereum and major EVM chains.

Ethereum plus every major EVM chain, including Polygon, Arbitrum, Base, Optimism, BNB Chain, and Avalanche, through one endpoint format. The same key also covers non-EVM chains like Solana and Bitcoin, 120+ in total.

Yes. Live USD prices, market caps, and volumes for Ethereum and EVM tokens, drawn from coverage of 100,000+ coins across chains. Balances come back already priced.

Yes. The CoinStats free tier includes 20,000 credits per month at 2 requests per second, no credit card required. It is the same data available on paid plans at a lower limit, enough to prototype and ship.

Credit-based. Each plan includes a monthly credit allowance, and each endpoint costs credits by complexity, not a flat request cap. Start free with 20,000 credits per month and upgrade for higher limits. Usage is visible live in the dashboard.

Create a free account, generate an API key from the dashboard, and make your first Ethereum request in minutes using the examples in the docs. The free tier is enough to build and test a full integration.
